The Challenges of Creating a Frontier-Level LLM

The recent release of Llama 4 [1] was far from perfect, but there is a lot that can be learned from this new generation of models. Put simply, Llama 4 is a massive pivot in Meta’s research direction. In response to increasing competition, Meta is reinventing the Llama series and clearly pushing to create a frontier-level LLM. Giv…

The State of Reinforcement Learning for LLM Reasoning

A lot has happened this month, especially with the releases of new flagship models like GPT-4.5 and Llama 4. But you might have noticed that reactions to these releases were relatively muted. Why?

What we learned from reading ~100 AI safety evaluations

In this blog, Conor Griffin and Julian Jacobs review a batch of AI safety evaluations that were published in 2024. We ask what we can learn from this body of work and make the case for scaling up this practice of ‘AI meta evaluation’. Like all the pieces you read here, it is written in a personal capacity. If you are doing work in this space, or have ideas, please …
