The new GRPO stabilisation trick from Prime Intellect has just landed in TRL! To use it, install from main with pip install git+github.com/huggingface/tr… and then set `delta > 1 + epsilon` in GRPOConfig :)

What an incredible trajectory of performance improvements for the reasoning models since the original o1-preview ! 60%+ winrates are comparatively huge, and few model upgrades achieved this historically

we are going to take a little more time with our open-weights model, i.e. expect it later this summer but not june. our research team did something unexpected and quite amazing and we think it will be very very worth the wait, but needs a bit longer.

After all the comments around OpenAI possibly serving a new model or distilled model we retested the data to check tldr: no performance change was noticed We reran o3 against our original results in April and saw the same perf Price reduction is real!
