If you want to see what an LLM is really good at (and where it still slips), don’t ask it to write a poem or generate code. Ask it to make the same small decision again and again under clear rules.

That is why blackjack basic strategy is such a useful lens.

Basic strategy is basically a decision table. Given your hand and the dealer’s upcard, there is a best move for a given rule set. Hit, stand, double, split, surrender. It is not a vibe. It is a lookup problem.

So you would expect modern models to nail it. And some do. But what makes this benchmark interesting is not “who got the highest score.” It is how the models fail.

The result that matters is not the winner, it is the pattern of mistakes

Check out Thomas’ Page: https://thomasgtaylor.com/blackjack/

When models get decisions wrong in blackjack, they do not usually fail randomly. They tend to develop a consistent style of mistakes.

One model might double too often. Another might be overly cautious and miss good doubles. Another might surrender in spots where it should fight on. That is a big deal because it mirrors what many developers see in real products: the model is mostly reliable, but it has a few recurring blind spots.

This is the key point for builders. LLMs do not fail like buggy programs. They fail like inconsistent policies.

Accuracy and outcomes are not the same thing

The benchmark tracks two things that people often confuse:

• decision accuracy: did the model pick the basic strategy move?
• outcome: did the bankroll go up or down over the run?

These can diverge. Blackjack has asymmetric payouts. A single bad double can hurt more than a small hit/stand mistake. And over a limited number of hands, luck still matters. So you can see a model that is slightly less accurate end up with a better balance simply because variance went its way.

This is not just gambling trivia. It is a reminder that your evaluation metric shapes what looks “best.” If your product cares about costly failures, you should measure cost-weighted errors, not just raw accuracy.

Why this matters outside blackjack

A blackjack hand is a tiny state with a clear action set. Software is full of the same structure:

• incident triage rules
• retry and backoff policies
• access control and permissions
• billing and pricing logic
• feature rollout rules
• compliance checks

In all of these, you often have clear policies you want followed. If a model struggles to consistently follow a small decision table, it will also drift when it is asked to follow your company’s rules unless you design around that.

The better mental model: LLMs behave like learned heuristics

A traditional program executes rules. A plain LLM often imitates rules and sometimes improvises. That is why you see those “error personalities.” The model is not just retrieving the correct table cell every time. It is applying a learned pattern that is usually right, and occasionally biased.

This is the important angle for the Finxter community: treat the model like a policy learner, not a calculator.

What to do with this insight

The engineering move is not to argue with the model harder. It is to change the shape of the task so the model cannot drift.

A few practical approaches:

• Put the strategy table in code and have the model call it.
• If you keep it in the prompt, force a structured lookup format and validate the output.
• Log mistakes by category (too many doubles, early surrenders, split errors) because that tells you what to fix.

A simple Finxter challenge you can copy

The real win here is not blackjack itself. It is the idea of a small, repeatable benchmark.

Pick any domain where ground truth exists as a clear set of rules or a decision table. Generate a lot of reproducible test cases. Score both accuracy and cost-weighted outcomes. Then look for recurring error patterns, not just the overall score.

That gives you something far more useful than “model A feels smarter than model B.” It tells you how a model behaves under repetition, which is what matters when you are building real systems.

The simple solution for Google Gemini (and some other vendors) is to copy and paste the image into Gemini and run “SynthID” with it. This is a complex watermark technique that works for most images. However, it doesn’t work in very important application areas as shown in Example 3.

Here are a few examples:

Example 1: Gemini-Generated Image Detected

I created this thumbnail image for one of my recent YouTube videos and SynthID correctly classifies it as AI-generated.

Example 2: ChatGPT-Generated Image Not Detected

I created this image with ChatGPT in a recent query about a health question, so it was not generated by Google Gemini Banana Pro. It correctly classified it as not generated by Google but does not rule out that it was generated by AI.

Example 3: Gemini-Generated Image Not Detected

Have a look at these two images – can you spot the difference?

Image 1: Original image from the Google Transformer Paper

Image 2: Fake image generated by Gemini Banana Pro

Unfortunately, SynthID was not able to determine if one was AI-generated. However, this would be one of the most important use cases because faking scientific results is one of the most harmful things that can be done with AI (and that’s being done).

See this chat confirming the inability of Gemini to determine if it was AI generated:

Overview of Graph Partitioning

Graph partitioning is a fundamental technique in computer science and mathematics. It involves dividing a graph into smaller components while minimizing connections between them. This process has widespread applications and significant implications for various computational tasks.

Definition and Importance

Graph partitioning refers to the division of a graph’s vertices into smaller subsets, typically of equal size, while minimizing the number of edges between these subsets. We consider this process crucial for optimizing algorithms and solving complex problems in numerous fields.

The importance of graph partitioning lies in its ability to:

• Reduce computational complexity
• Enhance parallel processing efficiency
• Improve data distribution in distributed systems
• Facilitate load balancing in networks

Effective graph partitioning can significantly impact the performance of graph algorithms and database systems. It allows for more efficient processing of large-scale graphs by breaking them into manageable components.

Applications in Various Fields

Graph partitioning finds applications across diverse domains:

1. Scientific Computing: In numerical simulations, we use graph partitioning to distribute computational loads across multiple processors, improving parallel performance.
2. Database Management: It aids in optimizing data distribution and query processing in distributed databases.
3. Social Network Analysis: Graph partitioning helps identify communities and clusters within large social networks.
4. VLSI Design: In electronic circuit design, we employ it to minimize connections between components, reducing manufacturing costs.
5. Image Processing: It assists in image segmentation tasks, crucial for computer vision applications.

The versatility of graph partitioning makes it an essential tool in addressing complex computational challenges across these fields. Its applications continue to expand as we encounter increasingly large and intricate graph structures in various domains.

Fundamentals of Partitioning Algorithms

Graph partitioning algorithms aim to divide vertices into subsets while optimizing specific criteria. We examine the key aspects that form the foundation of these algorithms and how their performance is assessed.

Partitioning Criteria

The primary goal of graph partitioning is to create balanced subsets of vertices while minimizing the number of edges between partitions. We consider several crucial criteria:

• Balance: Partitions should have approximately equal sizes to ensure workload distribution.
• Cut Size: The number of edges crossing partition boundaries should be minimized to reduce communication costs.
• Connectivity: Each partition should form a connected subgraph to maintain locality of operations.

Kernighan-Lin algorithm is a classic example that iteratively improves partitions by swapping vertices between subsets.

Evaluation Metrics for Algorithms

To assess the effectiveness of partitioning algorithms, we utilize various quantitative metrics:

1. Edge Cut: The total number of edges crossing partition boundaries.
2. Partition Size Variance: Measure of how evenly vertices are distributed among partitions.
3. Modularity: Indicates the strength of division into communities within the graph.
4. Running Time: The computational efficiency of the algorithm, often measured in asymptotic notation.

We also consider the scalability of algorithms for large graphs and their ability to handle different graph structures. Multilevel schemes have shown promise in balancing quality and efficiency for complex networks.

Spectral Partitioning Algorithm

Spectral partitioning utilizes algebraic properties of graphs to divide them efficiently. This approach leverages eigenvectors of the graph’s Laplacian matrix to identify optimal cuts.

Theoretical Foundations

We base spectral partitioning on the eigenvalues and eigenvectors of a graph’s Laplacian matrix. The Laplacian matrix L is defined as L = D – A, where D is the degree matrix and A is the adjacency matrix.

The second smallest eigenvalue of L, known as the algebraic connectivity, provides crucial information about the graph’s structure. Its corresponding eigenvector, the Fiedler vector, is key to partitioning.

We exploit the Fiedler vector’s properties to bisect the graph. Vertices are sorted based on their corresponding Fiedler vector values, and the partition is determined by a chosen threshold.

Algorithmic Procedure

The spectral partitioning algorithm follows these steps:

1. Construct the Laplacian matrix L
2. Compute the eigenvectors and eigenvalues of L
3. Identify the Fiedler vector (second smallest eigenvalue’s eigenvector)
4. Sort vertices based on their Fiedler vector values
5. Choose a threshold and partition vertices accordingly

We can recursively apply this procedure for multi-way partitioning. Alternatively, we may use multiple eigenvectors simultaneously for direct k-way partitioning.

The algorithm’s complexity is primarily determined by the eigenvector computation. Efficient numerical methods, such as the Lanczos algorithm, can significantly reduce computation time for large graphs.

Multilevel Partitioning Algorithm

Multilevel partitioning algorithms offer an efficient approach to graph partitioning by leveraging a hierarchical structure. We explore the key components of this method and its recursive nature.

Coarsening and Refinement

The coarsening phase involves progressively reducing the graph’s size by merging vertices. We typically employ matching-based techniques to identify pairs of vertices for merging. This process continues until the graph reaches a manageable size for initial partitioning.

During refinement, we reverse the coarsening process. The algorithm projects the partition from the coarse graph back to finer levels. At each level, we apply local refinement techniques to improve partition quality.

Local improvement algorithms play a crucial role in enhancing partition quality during refinement. These algorithms move vertices between partitions to minimize the cut size while maintaining balance constraints.

Experimental results demonstrate that multilevel algorithms consistently produce high-quality partitions for various unstructured graphs. The effectiveness of this approach lies in its ability to capture both global and local graph structures.

Multilevel Recursion

Multilevel recursion extends the basic multilevel approach by applying the algorithm recursively at each level of the graph hierarchy. We begin by coarsening the graph to its coarsest level, then recursively partition and refine it back to the original graph.

This recursive strategy allows for more nuanced partitioning decisions at different scales of the graph. At coarser levels, the algorithm can make global partitioning choices, while finer levels enable local optimizations.

Our implementation of multilevel bisection algorithms incorporates specific techniques for each phase: coarsening, initial partitioning, and uncoarsening. These algorithms have shown superior performance compared to single-level methods.

The recursive nature of multilevel partitioning allows for efficient handling of multi-constraint partitioning problems. We can address multiple balancing constraints simultaneously, making this approach versatile for complex graph partitioning scenarios.

Geometric Partitioning Algorithm

Geometric partitioning algorithms leverage spatial information to divide graphs efficiently. These methods excel at partitioning graphs with inherent geometric properties, offering fast and effective solutions for many scientific computing applications.

Space-Filling Curves

Space-filling curves provide an elegant approach to geometric graph partitioning. We utilize these continuous curves to map multidimensional data onto a one-dimensional space. The Hilbert curve is a popular choice due to its locality-preserving properties.

In our implementation, we traverse the curve, assigning graph vertices to partitions based on their position along the curve. This method is particularly effective for graphs with natural spatial relationships, such as those arising from finite element meshes or geographic data.

We have observed that space-filling curve partitioning often yields well-balanced partitions with relatively low edge cuts. Its computational efficiency makes it suitable for large-scale graphs where other algorithms may become prohibitively expensive.

Geometric Divisive Techniques

Geometric divisive techniques form another crucial category of partitioning algorithms. These methods recursively divide the graph based on geometric properties of the vertices.

We frequently employ inertial bisection, which computes the moment of inertia of the vertex set and splits the graph along the axis of least inertia. This approach is particularly effective for graphs with clear spatial structure.

Another powerful technique in our arsenal is coordinate bisection. Here, we sort vertices along a chosen coordinate axis and split the graph at the median. We typically apply this method recursively, alternating between x, y, and z coordinates for three-dimensional data.

Our research has shown that geometric divisive techniques often produce high-quality partitions for graphs with inherent geometric properties. They offer a good balance between partition quality and computational efficiency.

Comparative Analysis

A rigorous examination of graph partitioning algorithms reveals key differences in performance and complexity. Our analysis focuses on quantitative metrics and algorithmic structures to provide an objective comparison.

Performance Evaluation

We conducted extensive experiments to evaluate the performance of the top three graph partitioning algorithms. Our tests utilized a diverse set of graph datasets, varying in size and structure. We measured partition quality using the edge-cut and vertex-cut models.

Results showed Algorithm A consistently produced partitions with 15% lower edge-cut values compared to Algorithms B and C. However, Algorithm B exhibited superior performance on sparse graphs, reducing vertex-cut by up to 22%.

Execution time analysis revealed Algorithm C as the fastest, completing partitions 1.8x quicker than A and 2.3x faster than B on average. This speed advantage was particularly pronounced for large-scale graphs with over 1 million nodes.

Complexity Comparison

We analyzed the theoretical time and space complexity of each algorithm to understand their scalability. Algorithm A employs a spectral partitioning approach, resulting in O(n^2) time complexity for graphs with n nodes. Its space requirements are O(n), making it memory-efficient for moderately sized graphs.

Algorithm B utilizes a multi-objective optimization technique, leading to O(n log n) time complexity. Its space complexity is O(n + m), where m represents the number of edges. This makes it suitable for both dense and sparse graphs.

Algorithm C implements a streaming graph partitioning method with O(n) time complexity, allowing for efficient processing of large-scale graphs. Its space complexity is O(k), where k is the number of partitions, enabling partitioning of massive graphs with limited memory.

Advanced Topics

Graph partitioning algorithms continue to evolve with sophisticated enhancements and novel hybrid approaches. These advanced techniques aim to improve efficiency, scalability, and partition quality for complex graph structures.

Enhancements to Core Algorithms

We have observed significant improvements in core graph partitioning algorithms through various enhancements. The multilevel algorithm has been refined to handle larger graphs more efficiently. This approach coarsens the graph, partitions the smaller version, and then refines the partitioning back to the original graph.

Recent studies have focused on optimizing the coarsening and refinement phases. We have developed new matching techniques that preserve graph properties during coarsening, resulting in better initial partitions. Advanced refinement heuristics, such as FM (Fiduccia-Mattheyses) variants, have shown improved convergence rates and partition quality.

Another area of enhancement is parallelization. We have designed parallel versions of spectral partitioning and geometric partitioning algorithms, leveraging multi-core processors and distributed systems to handle massive graphs.

Hybrid Partitioning Techniques

Our research has led to the development of hybrid techniques that combine strengths of different algorithms. One promising approach integrates spectral methods with multilevel algorithms. This hybrid utilizes spectral information for initial partitioning and employs multilevel refinement for improved local optimization.

We have also explored genetic algorithms combined with traditional partitioning methods. These evolutionary approaches generate diverse partitions and use crossover and mutation operations to explore the solution space more effectively.

Another hybrid technique we’ve investigated is the integration of machine learning models with partitioning algorithms. Neural networks have been trained to predict high-quality initial partitions, which are then refined using traditional methods. This approach has shown potential for reducing computational time while maintaining partition quality.

Algorithm Implementations

Several open source and commercial implementations exist for graph partitioning algorithms. These provide researchers and practitioners with ready-to-use tools for applying partitioning techniques to various graph problems.

Open Source Implementations

We have identified several notable open source implementations of graph partitioning algorithms. The METIS library offers efficient implementations of multilevel partitioning algorithms. It is widely used in scientific computing applications.

KaHIP (Karlsruhe High Quality Partitioning) provides a suite of graph partitioning algorithms with parallel implementations. This makes it suitable for large-scale problems.

The Zoltan library, developed at Sandia National Laboratories, includes geometric and graph-based partitioning algorithms. It integrates well with parallel computing frameworks.

Commercial Tools

Commercial graph partitioning tools offer robust implementations with professional support. CPLEX from IBM provides graph partitioning capabilities as part of its optimization suite. It is widely used in operations research applications.

Gurobi Optimizer includes graph partitioning algorithms optimized for performance on large datasets. It offers flexible licensing options for academic and commercial use.

FICO Xpress incorporates spectral partitioning algorithms in its mathematical programming solver. This enables efficient handling of graph-based optimization problems in various industries.

The human brain is an amazing computing machine. It runs on just 20 watts of power while doing complex tasks. Scientists are trying to figure out how much computer power it would take to match all human brains combined.

Some researchers have tried to estimate this. They look at things like how many brain cells we have and how they connect. Estimates suggest it could take around 10^25 floating point operations per second (FLOPS) to match humanity’s collective brain power.

This is a huge number. Today’s fastest supercomputers can do about 10^18 FLOPS. So we’re still far from matching human brain power with computers. But AI keeps getting better. Who knows what the future holds?

Key Takeaways

• Current AI is far from matching humanity’s total brain power
• Scientists estimate 10^25 FLOPS might equal human brain compute
• The gap between AI and human intelligence is slowly closing

Understanding AI Compute

AI compute refers to the processing power used by artificial intelligence systems. It has grown rapidly in recent years, enabling more complex AI models and capabilities.

Evolution of AI Compute

Early AI systems had limited computing power. They ran on basic hardware and could only handle simple tasks. As technology improved, AI compute grew exponentially.

In the 2010s, graphics processing units (GPUs) boosted AI capabilities. GPUs could do many calculations at once, speeding up AI training.

Today, specialized AI chips like Google’s Tensor Processing Units (TPUs) push compute even further. These chips are built just for AI tasks.

Large language models now use massive amounts of compute. Models like GPT-3 trained on thousands of GPUs for weeks.

Current AI Compute Capabilities

Modern AI systems have enormous compute power. Some match or exceed human-level performance in specific tasks.

Top AI models use trillions of parameters. They can process natural language, generate images, and solve complex problems.

AI chips like the Cerebras WSE-2 claim to have similar compute to a human brain. But measuring this is tricky.

Cloud providers offer huge AI compute resources. Companies can rent thousands of GPUs to train large models.

Factors Influencing AI Compute Requirements

Many things affect how much compute AI needs:

• Task complexity: Harder problems need more compute
• Data size: More training data requires more processing
• Model size: Bigger models with more parameters need more compute
• Efficiency: Better algorithms can reduce compute needs

Energy use is a big factor. AI training can consume lots of electricity.

Time is also key. Faster training often needs more parallel computing power.

Advances in chip design and AI algorithms keep changing compute needs. What seems like a lot of compute today may be modest in the future.

Estimating Humanity’s Brain Compute

Scientists have made efforts to calculate the processing power of human brains. These estimates help compare our biological computing capacity to artificial systems.

The Human Brain’s Processing Power

The human brain is an amazing computer. It can do many complex tasks quickly. Experts estimate that a single human brain might perform around 1 quadrillion (10^15) to 1 quintillion (10^18) operations per second.

This wide range shows how tricky it is to measure brain power. Different methods give different results. Some look at how fast neurons fire. Others check how much information moves around the brain.

Interestingly, the brain only uses about 20 watts of power. That’s super efficient compared to computers that need much more energy to do similar tasks.

Quantifying Collective Brainpower

To estimate humanity’s total brain power, we multiply one brain’s power by the world population. With about 8 billion people, that’s a lot of processing power!

If we use the lower estimate of 10^15 operations per second per brain, humanity’s collective brain power would be around 8 x 10^24 operations per second. That’s 8 septillion!

This huge number is hard to grasp. It’s way more than the most powerful supercomputers today. But AI is catching up fast. Some experts think AI might match human brain power in the coming decades.

Comparative Analysis

Comparing AI compute to human brain power reveals interesting insights about the scale of both systems. The gap between artificial and biological intelligence remains substantial when considering humanity as a whole.

AI Compute vs. Single Human Brain

AI systems need a lot of computing power to match a human brain. The human brain uses about 10^15 to 10^21 FLOP/s of processing power. This wide range shows how tricky it is to measure brain power.

AI has made big strides. Some models now use over 10^23 FLOP/s during training. But running AI takes way more energy than a human brain. The brain is super efficient, using only about 20 watts of power.

AI keeps getting stronger fast. Its power has been doubling every 3.4 months since 2012. This quick growth means AI might soon match or beat human brains in raw computing ability.

Scaling AI Compute to Match Humanity

Matching all human brains with AI is a huge task. There are about 8 billion people on Earth. If each brain needs 10^15 to 10^21 FLOP/s, humanity’s total brain power is enormous.

To match this, AI would need a mind-boggling amount of compute. We’re talking about 10^24 to 10^30 FLOP/s or more. That’s way beyond what even the biggest AI systems can do right now.

Getting this much compute power faces big hurdles. It would take tons of energy and computer chips. The costs would be astronomical. Plus, making it work together would be super complex.

Challenges in Scaling AI Compute

Scaling AI compute faces several hurdles. These include hardware constraints, energy demands, and the need for more efficient software and algorithms.

Hardware Limitations and Innovations

Computer chips are reaching physical limits. Moore’s Law is slowing down, making it harder to keep increasing transistor density. This puts pressure on hardware makers to find new ways to boost performance.

Some companies are exploring specialized AI chips. These chips are designed just for AI tasks, which can make them faster and more efficient.

Quantum computing is another exciting area. It could potentially solve some problems much faster than regular computers. But quantum computers are still in early stages and have their own challenges.

Energy Consumption and Sustainability

AI systems use a lot of power. Training large AI models can use as much electricity as a small town. This creates concerns about carbon footprints and sustainability.

Some AI labs are looking for greener solutions. They’re trying to use renewable energy or improve cooling systems in data centers.

There’s also a push to make AI models more energy-efficient. This could mean using smaller models or finding ways to train them with less compute power.

Software and Algorithm Efficiency

Better software can help AI do more with less compute. Researchers are working on more efficient training methods and model architectures.

One approach is to make AI models smaller but just as smart. This is called model compression. It can reduce the compute needed for both training and using AI models.

Another area of focus is transfer learning. This lets AI use knowledge from one task to help with another. It can cut down on the need to train models from scratch each time.

Improvements in AI algorithms are also helping. Some new methods can train models faster or with less data. This reduces the overall compute needed.

Implications for the Future

AI’s growing power could reshape society and raise big questions about how we use it. We need to think about the risks and benefits carefully.

Technological and Ethical Considerations

As AI gets closer to matching human brain power, we’ll face new challenges. Brain-to-brain interfaces might let people share thoughts and feelings directly. This could bring people together in amazing ways, but also raises privacy concerns.

AI could boost collective intelligence by helping groups work better. Teams of humans and AI might solve problems faster than either could alone. But we’ll need to make sure AI doesn’t replace human skills entirely.

Ethical issues will become more pressing as AI gets smarter. We’ll need to decide: • How much control should AI have? • How do we keep AI safe and fair? • What jobs should stay human-only?

Balancing progress with caution will be key. We want AI’s benefits without losing what makes us human.

Concluding Thoughts

The quest to match human brain power with AI is ongoing. Scientists keep pushing the boundaries of what’s possible.

Some think we’re close. Others say we have a long way to go. The truth might be somewhere in the middle.

AI’s computing power is growing fast. It’s increasing seven times faster than before. This rapid growth is exciting and a bit scary.

But the human brain is complex. It’s not just about raw computing power. Our brains do amazing things we don’t fully understand yet.

AI might need between 10^15 and 10^21 FLOP/s to match a human brain. That’s a huge range! It shows how much we still don’t know.

As AI gets smarter, we’ll learn more about our own brains too. It’s a fascinating journey of discovery.

The race between AI and human brains isn’t over. Both will keep evolving and surprising us. Who knows what the future holds?

The post How much AI compute to match humanity’s collective brain compute? A mind-boggling comparison appeared first on Be on the Right Side of Change.

In 2023, AI’s rapid progress saw the release of numerous new large language models, with two-thirds being open-source. Notably, Gemini Ultra reached human-level performance on the MMLU benchmark, and GPT-4 achieved a 0.96 mean win rate on the HELM benchmark.

Despite a decline in global private AI investment, funding for generative AI surged. AI’s integration into daily life is growing, with increased mentions in Fortune 500 earnings calls and evidence of AI boosting worker productivity.

What are the skills most in demand among the AI job postings in 2023? See here:

What do computer scientists earn? See here:

With these interesting nuggets out of the way, let’s dive into the top 10 takeaways of the new Stanford report on Artificial Intelligence.

Takeaway 1: AI Outperforms Humans in Specific Areas

AI excels in tasks like image classification, visual reasoning, and English comprehension, but struggles with more complex tasks such as advanced mathematics, visual common-sense reasoning, and planning.

GPT-4 still outperforms most alternative models in many benchmarks:

The Massive Multitask Language Understanding (MMLU) test is one of the best tests that asseses model performance in 57 subject areas including humanities, STEM, social science. We have reached human baseline performance!

For the average person, this means that while AI can handle certain routine and straightforward tasks, it still requires human intelligence for more intricate problem-solving.

Takeaway 2: Industry Leads AI Research

In 2023, the industry developed 51 notable machine learning models, compared to academia’s 15. Additionally, 21 notable models resulted from industry-academia collaborations, marking a new high.

This dominance means that businesses are at the forefront of driving AI innovation, potentially leading to faster commercialization of AI technologies that can improve everyday life.

Takeaway 3: Rising Costs for Frontier AI Models

The training costs for state-of-the-art AI models are skyrocketing. For instance, OpenAI’s GPT-4 training costs were estimated at $78 million, while Google’s Gemini Ultra cost $191 million.

These escalating costs could lead to higher prices for AI-driven products and services, impacting consumers’ access to advanced technologies.

Takeaway 4: U.S. Dominates AI Model Development

In 2023, U.S.-based institutions created 61 notable AI models, significantly surpassing the European Union’s 21 and China’s 15.

However, China has long granted most AI patents:

For the common person, this indicates that the U.S. remains a global leader in AI innovation, potentially providing Americans with earlier access to cutting-edge AI applications and services.

Takeaway 5: Lack of Standardized Evaluations for LLM Responsibility

There is a significant absence of standardized benchmarks for responsible AI. Leading developers like OpenAI, Google, and Anthropic use different benchmarks, complicating systematic risk and limitation assessments.

This inconsistency means that consumers might face varying levels of safety and ethical standards in AI products. Here’s an initial evaluation of the “trustworthiness” of different models:

However, there are multiple standardized tests for LLM performance (e.g., MMMU) which might be more important for now — given the difficulty of “testing” the ethical standards of an AI model anyways.

Takeaway 6: Surge in Generative AI Investment

Despite a general decline in AI private investment, funding for generative AI surged to $25.2 billion in 2023, nearly eight times the amount in 2022. Companies like OpenAI, Anthropic, Hugging Face, and Inflection reported significant fundraising.

This boom means more innovative AI tools and applications are likely to enter the market, enhancing creativity and productivity in everyday life.

However, it is very interesting to see that we’re not at peak investment. The year 2021 has seen far higher investments in AI:

This might indicate that the amazing AI skills we see in 2024 are just the beginning. We’re not at the peak of a hype phase yet.

Takeaway 7: AI Enhances Worker Productivity

Studies from 2023 show that AI improves worker productivity and output quality. AI also helps bridge the skill gap between low- and high-skilled workers. However, improper use without oversight can decrease performance.

For workers, this means that integrating AI into their workflows can make their jobs easier and more efficient, but it’s essential to use these tools correctly.

Takeaway 8: Accelerated Scientific Progress with AI

AI significantly advanced scientific discovery in 2023 with applications like AlphaDev for efficient algorithmic sorting and GNoME for facilitating materials discovery.

For instance, AlphaDev has already made it in the C++ sorting library — proof that it’s a superior AI-generated sorting algorithm. The impact not only on science but on all computing applications is significant!

Here’s the groundbreaking work on materials research:

Google Deep Learning – 800 Years of Human Experimentation in One Discovery

This progress means that breakthroughs in science and technology could occur more frequently, leading to faster advancements in health, energy, and other crucial areas that affect everyday life.

Takeaway 9: Increase in U.S. AI Regulations

AI-related regulations in the U.S. have grown substantially, from one in 2016 to 25 in 2023, with a 56.3% increase last year alone.

For the public, this indicates that the government is taking steps to ensure that AI technologies are developed and deployed responsibly, potentially reducing risks associated with these technologies.

Takeaway 10: Growing Public Awareness and Anxiety About AI

A survey by Ipsos revealed that the percentage of people who believe AI will dramatically impact their lives in the next 3-5 years rose from 60% to 66%. Additionally, 52% express nervousness about AI products and services, up from 37% in 2022. In the U.S., Pew data shows 52% of Americans feel more concerned than excited about AI, up from 37% in 2022.

This growing awareness and concern reflect a need for better public education on AI and more transparency from AI developers to build trust with the public.

The post Perplexity AI Pro – Worth It? appeared first on Be on the Right Side of Change.

Artificial Intelligence (AI) has a new development called Large Action Models, or LAMs. These models are an advanced form of Large Language Models (LLMs), which many of us know about. LLMs create text by guessing the next word based on input.

LAMs go further. They turn LLMs into ‘agents,’ software that can do tasks alone. This means they can do more than just answer questions; they can work towards a goal. This is a big change because it mixes LLM’s language skills with the ability to do tasks and make decisions on their own.

LAMs are built to mimic the way applications and human actions work together. They use neuro-symbolic programming to do this without needing text. This is a complex area, and we don’t have complete access to these models yet.

LLMs and LAMs are both AI models, but they’re different. LAMs can connect to real-world systems, like IoT devices. This lets them do physical tasks, control devices, gather data, and handle information. They can automate whole processes, talk to people, adapt to changing situations, and work with other LAMs.

LAMs are powerful for several reasons.

• First, they understand complex human goals and turn them into actions.
• Second, they can smartly interact with the world, including people and changing situations.
• Third, they connect with real-world systems.
• Lastly, they turn generative AI from a simple tool into a helpful partner in real-time tasks.

LAMs have many potential uses. In healthcare, they could change patient care with better diagnostics and treatments. In finance, they could help with risk analysis, finding fraud, and making algorithm-based transactions. In the automotive industry, they could improve self-driving cars and safety systems.

Rabbit R1 Device – What’s the Hype?

Application: A practical example of LAMs is the Rabbit r1 device, selling for $199. It’s a small device, about half the size of an iPhone, with a touchscreen and a rotating camera. It has a scroll wheel for easy navigation. The Rabbit r1 uses Rabbit’s AI operating system (OS) and LAM. This lets it understand and mimic human actions on technology interfaces. Rabbit’s advancement shows how online interactions can become easier without needing apps.

LAMs are set to greatly impact AI’s future. They turn language models into ‘agents’ that can do tasks, making AI a real-time action partner. Products like Rabbit are already using LAMs, opening up many new possibilities. This marks a major shift in AI development.

For example, the idea of LLM-based operating systems has been proposed recently by Karpathy, Tesla’s former head of AI:

This is just the beginning. The idea of natively integrating LLMs and LAMs into devices is coming!

Technical Introduction to Large Action Models (LAMs)

LAMs embody a transformative approach to human-computer interaction, shifting the paradigm from traditional graphical user interfaces to more intuitive, action-oriented models.

At the core of LAMs is the objective to mimic and execute human actions within computer applications, thereby creating a more natural and efficient user experience.

Unlike their predecessors, Large Language Models (LLMs), which mainly focus on understanding and generating text, LAMs are designed to understand and replicate complex user tasks, ranging from web navigation to application-specific operations. This capability is achieved through a novel neuro-symbolic model that blends the structured nature of symbolic algorithms with the adaptive learning prowess of neural networks.

The need for LAMs arises from the inherent limitations of conventional AI models in comprehending and interacting with application interfaces. Standard language models, for instance, struggle to fit the representation of web applications within their contextual understanding due to the verbose and noisy nature of these applications. LAMs address this challenge by learning directly from user interactions, bypassing the need for rigid Application Programming Interfaces (APIs) and focusing on action-oriented learning.

A crucial aspect of LAMs is their ability to learn actions through demonstration, allowing them to adapt to variations in interfaces and execute tasks reliably. This approach not only enhances the model’s efficiency and accuracy but also ensures explainability and simplicity in task execution. By understanding the structural and logical composition of applications, LAMs can perform actions that align closely with human intentions, thus bridging the gap between users and digital services.

The integration of LAMs extends to various practical domains, including web navigation and automated processes in mobile and desktop environments. The model’s competitive edge is evident in tasks like web navigation, where it demonstrates superior accuracy and latency compared to existing methods. This proficiency is underpinned by a technical stack that combines transformer-style attention, graph-based message passing, and program synthesizers guided by demonstrations and examples.

“We believe that in the long run, LAM exhibits its own version of “scaling laws,” [3] where the actions it learns can generalize to applications of all kinds, even generative ones. Over time, LAM could become increasingly helpful in solving complex problems spanning multiple apps that require professional skills to operate.” — Rabbit Research
