Hello and welcome to Sync #493!

This week, we will take a closer look at the leaks emerging from leading AI labs, suggesting that researchers are hitting a wall, and explore what can be done to overcome it.

Elsewhere in AI, OpenAI is reportedly planning to release a new AI agent capable of controlling users’ computers. Meanwhile, Anthropic has teamed up with Palantir and AWS to sell its AI models to defence customers, X is testing a free version of its AI chatbot Grok, and AI Granny is wasting scammers’ time.

In robotics, Waymo One is now available to everyone in LA, Agility Robotics’ Digit has found a new job, and a drone has successfully delivered blood samples between two hospitals in London.

Additionally, AlphaFold3 is now open source (at least the code is), one researcher has demonstrated how a cluster of human brain cells learned to control a virtual butterfly, and YouTube’s chief mad biologist has found a way to turn shrimps into fabric.

Enjoy!

Cracks in the Scaling Laws

If someone were to write a history book about generative AI and large language models, two milestones in AI research would probably get their own chapters. The first milestone happened in 2017 when eight Google Brain researchers published a paper titled Attention Is All You Need. It was a landmark paper which introduced the concept of transformer, the bedrock of all modern large language models. The second chapter would be dedicated to a pair of events—the launch of ChatGPT in November 2022 and the release of GPT-4 in March 2023. That’s when the idea of large language models entered the global scene and kickstarted the AI revolution we are in today.

However, between these two milestones, there was another event that bridged them. That event was the publication of a paper from OpenAI titled Scaling Laws for Neural Language Models, published in January 2020. Essentially, what researchers have found is that the performance of a large language model scales up predictably depending on the allocated compute power, training dataset size or model’s parameters.

Later follow-up papers from OpenAI and DeepMind confirmed the original results and expanded upon them. For OpenAI, the discovery of scaling laws was a green light for fully committing to large language models. If the scaling laws hold, then with enough computing power, a big enough training dataset and with big enough model, a highly capable, nearing human-level performance AI model is within reach.

And OpenAI went full-on with large language models. Five months after the Scaling Laws for Neural Language Models paper was published, in May 2020, Microsoft agreed to build what was at that time one of the largest supercomputers, containing 10,000 GPUs, just for OpenAI to train massive models. That set off the AI industry on the path it is now—building more and more powerful supercomputers, fed with ever-increasing amounts of data to train larger and larger, and more capable, models.

That trend, of increasing resources thrown at the model and getting better results, held on. We’ve seen significant leaps in performance with each new generation of large language models. This fueled optimism and raised expectations for the next generation of AI models—GPT-5, Gemini 2, and Claude 4—which are now anticipated to reach entirely new levels of performance, massively surpassing their predecessors.

That, however, seems to not be the case. According to a report from The Information, OpenAI’s new model, codenamed Orion, shows better performance than GPT-4 but not as much as expected. Reportedly, the jump in performance is smaller than from GPT-3 to GPT-4. And OpenAI is not the only company experiencing this slowdown in the rate of improvements—The Verge reports that a similar thing is happening at Google DeepMind, too, saying that Gemini 2 “isn’t showing the performance gains the Demis Hassabis-led team had hoped for.”

That puts leading AI companies—OpenAI, Google DeepMind, Anthropic—in a tricky spot. Over the last two years, these companies have consistently delivered groundbreaking performance with each new model release. However, the reported gains are now said to be smaller than before. If the leaks are accurate, GPT-5 and Gemini 2 will be better than their predecessors but they won’t live up to the hype coming from being the next major upgrade.

The report from The Information suggests that OpenAI is looking into finding new ways of improving the performance of its next-generation model in the face of a dwindling supply of new training data. This involves new strategies such as using synthetic data produced by AI models or new ways to improve model post-training.

But there is also another path forward—adding new functionalities instead of massively improving the performance of next-generation models. That way AI companies can deliver new value to their customers without delivering a new level of raw performance. We already see this strategy in action. In September, OpenAI released o1, their first reasoning model. In October, Anthropic revealed Computer use which allows Claude to take control of user’s computer and perform actions on their behalf. OpenAI and Google are rumoured to introduce a similar feature, too, very soon.

Either way, the leading AI companies have to now justify the billions of dollars poured into them. One way or another, they have to find a way to overcome the wall they are facing.

Newest Google and Nvidia Chips Speed AI Training
This article details the latest test results of the MLPerf v4.1 benchmark, which evaluates AI hardware performance across six AI tasks: recommendation systems, GPT-3 and BERT-large pre-training, Llama 2 70B fine-tuning, object detection, graph node classification, and image generation. The benchmark featured the first results for Nvidia’s next-generation Blackwell architecture. The B200 GPU demonstrated double the performance of the H100 for GPT-3 training and LLM fine-tuning, along with a 64% improvement in recommendation systems and a 62% improvement in image generation. The benchmark also included Google’s latest AI accelerator, Trillium, which achieved up to a 3.8-fold performance improvement over the v5e TPU, an 8% improvement in GPT-3 training over the v5p TPU, and a two-minute reduction in training time. Overall, the results show that AI training performance is improving at twice the rate of Moore’s Law and advances in software and network scaling enable near-linear scaling with larger systems. However, energy consumption is a growing concern, as this is the first time MLPerf starting to track power usage.

‘AI Granny’ is happy to talk with phone scammers all day

This is one of the most beautiful uses of AI I’ve seen in recent months. O2 has released dAIsy, an AI Granny with infinite patience whose only job is to waste scammers’ time by being the most polite and annoying for scammers artificial grandma it can be. It would be interesting to see a follow-up in a few months to check if dAIsy has been effective or if this is simply a PR stunt to raise awareness about AI-powered phone scams.

Google DeepMind has a new way to look inside an AI’s “mind”
One area of AI research is mechanistic interpretability, which focuses on reverse-engineering how neural networks make decisions by analysing their internal workings. This article highlights work done by researchers at Google DeepMind to better understand the inner workings of AI. Using sparse autoencoders, which examine neural network layers, researchers can identify features (data categories representing broader concepts) and track their progression from input to output. Mechanistic interpretability could help ensure AI systems align with human intentions and values, paving the way for more trustworthy and safer AI by enabling precise control over their operations.

Oasis: A Universe in a Transformer
This is a very interesting project. Oasis is a video game in which every frame is generated by an AI model. There is an online playable demo, and the model and its weights are available for download to run the AI-generated version of Minecraft on your computer. I tried it and although it looks and feels like Minecraft, the model didn’t fully replicate Minecraft and the game was a little bit off. Nevertheless, Oasis is impressive and could offer a glimpse into how games of the future might be created. It also shows the potential generative AI has to generate whole virtual worlds not only for gaming but also for simulations and training robots.

Researchers use imitation learning to train surgical robots
Researchers have successfully trained a surgical robot to execute procedures as skillfully as human surgeons by using hundreds of surgical videos as training data. The robot learned to perform three fundamental surgical tasks: manipulating a needle, lifting body tissue, and suturing. It also demonstrated adaptability, such as picking up a dropped needle without specific instructions. This approach eliminates the need to program each step manually, though there is still a long way to go before autonomous surgical robots become a reality.
