TAI #125: Training Compute Scaling Saturating As Orion, Gemini 2.0, Grok 3, and Llama 4 Approach?

What happened this week in AI by Louie
This week, the potential plateauing of LLM training scaling laws has been a focus of debate in the AI community. The Information reported that OpenAI’s scaling of LLM training compute appears to be hitting a plateau, with more incremental gains in its latest model, Orion, than hoped relative to GPT-4. Reports of this slowing trend are not isolated to OpenAI. Google DeepMind, for instance, is expected to launch Gemini 2.0 in December, but reports have also suggested internal disappointment on improvements. Similarly, we recently discussed Anthropic’s delayed release of Opus 3.5, though CEO Dario Amodei has now confirmed they still plan to release it. Meanwhile, Meta’s LLaMA 4 and XAi’s Grok-3 are currently training on clusters of more than 100,000 H100 GPUs, with Grok-3 expected as soon as late 2024. Despite these investments, the anticipated performance gains across models may be smaller than the leap seen with previous generations, raising broader questions about the limits of traditional training compute “scaling laws.”
In May, OpenAI CEO Sam Altman expressed high hopes for Orion, the company’s upcoming flagship model, predicting it would be significantly more advanced than GPT-4. At the time, Orion’s training was reportedly only 20% complete, but it was already performing on par with GPT-4 in tasks and intelligence. However, as training progressed, Orion’s improvements have been more incremental, especially compared to the leap seen between GPT-3 and GPT-4, leading some within OpenAI to temper their expectations. As testing continues, OpenAI employees who have worked with Orion report that, while it shows notable progress on certain language tasks, its performance is inconsistent, particularly with more structured tasks like coding and complex problem-solving. For some applications, Orion’s capabilities don’t clearly surpass GPT-4. These mixed results have raised questions about whether Orion’s enhancements are enough to justify its increased operational costs.
OpenAI has yet to finish the final safety evaluations of Orion, which are expected to be publicly released early next year, with hints that it may depart from the traditional “GPT” branding to reflect its new direction. It is also possible that Orion is integrated into OpenAI’s new o1 reasoning model family to achieve further performance gains.
Why should you care?
Exactly what bottlenecks or dead ends will get in the way of continuing to improve LLM capabilities is a key factor in how quickly they will significantly transform the global economy and potentially even achieve AGI. While diminishing returns are natural to some extent — particularly after saturating many easier capabilities and benchmark tasks — LLMs still have a long way to go to match human performance on many tasks. We actually think current LLM capabilities are already enough for a huge global impact, but foundation LLMs need to be customized to specific tasks and companies to achieve the reliability and productivity gains needed for widescale adoption. This is currently bottlenecked by LLM Developer talent (we think many millions of LLM Developers will be needed, and we are trying to solve this with our Towards AI Academy), employee’s non-technical LLM education, and the time it takes to test and iterate these advanced LLM pipelines. Nevertheless, progress in foundation model capabilities can open up new use cases, and we would be very disappointed if progress stops here! However, we don’t think this is likely.
Despite recent press reports on disappointing gains from larger training compute budgets — Sam Altman and Dario Amoedi are both very optimistic in public statements (albeit with an incentive given fundraising needs!). Sam Altman, for example, said in a recent Reddit AMA he thinks AGI can be “achievable with current hardware.” Dario Amoedi meanwhile thinks “Powerful AI” will be achieved in 2026 or 2027. Recent newsflow from leading cloud providers lining up nuclear power for the energy needs of next-generation training clusters also contradicts the saturating returns narrative. Nevertheless, we think there have likely been disappointing results from training runs this year as companies have scaled to 50k+ H100 GPU clusters. Most likely, this is due to a bottleneck in diverse training data after saturating data that is easily scrapable from the internet. New data (real or synthetic) and new architectures may be needed to make the most of larger clusters. Training compute is not the only path to progress. However, we think huge progress has been made this year in both inference cost, and the underappreciated new inference compute scaling paradigm.
Foundation LLM capability improvement comes broadly from six sources: 1) Increased training compute budget (which is from more GPUs/TPUs, better GPUs, or longer training runs and can be spent on more parameters, more training data, or more FLOPs per forward/backward pass). 2) Increased utilization of this training compute (higher Maximum FLOPS Utilization, less downtime), 3) Higher quality training data, 4) More training compute efficient algorithms (e.g., MoE, new attention mechanisms), 5) Better mid-training/post-training performance unlocks and enhancement (e.g., RLHF, instruction tuning, monte carlo tree search) and 6) more recently Inference or Test Time compute scaling (increasing “thinking time/tokens” to solve harder problems). We think right now inference compute scaling is the most effective path to progress, so we would not be surprised to see the focus shift here from scaling training compute. We also think there is still a lot of room to experiment with new or modified model architectures. However, we think larger and larger training budgets will still be justified in parallel, given that even incremental gains relative to other techniques can still unlock huge economic value.
