We took @karpathy's advice and released MLGym, a gym environment for solving ML tasks. MLGym makes it easy to add new tasks so we hope the OSS community will help us scale it up. x.com/robertarail/st…

For friends of open source: imo the highest leverage thing you can do is help construct a high diversity of RL environments that help elicit LLM cognitive strategies. To build a gym of sorts. This is a highly parallelizable task, which favors a large community of collaborators.

Some personal news: I joined Google DeepMind in @_rockt's uber talented Open-Endedness team. I couldn’t be more excited for what we’re cooking. AI is the least open-ended it will ever be. Meta, it’s been a blast, an honor, and a privilege. I’m very grateful for the freedom and

We’ve been optimising LLM reasoning with RL before it was cool with @Dahoas1 @d_yuqing @tesatory @pabbeel @erichammy @sharathraparthy & co. But we never got to scale it. What other works did something similar before o1? Would love to trace the history of o1 and understand why
