OpenRSI Index

Not in model cards

Agents run autoresearch on real open-source model development projects with their original code, data and checkpoints, for 60 or more hours. Fixed verifiers score the result against the human recipe they started from.

Signature tasks, such as Qwen-122B RL and a Marin scaling-ladder optimizer, use 256 H100s and up to about 20,000 H100-hours per run. Public tasks need 1 to 8 H100s. Repo has 289 stars.
