1. [Important] Perhaps we should not add the safety score in the public eval, and mention in practice we suggest prompt tuning these models and deploying them with safety filters. or something similar.
2. Perhaps add Claude 4.5 Haiku released today ?
3. Perhaps mention in practice we see far deeper agentic trajectories and this will be an area of focus for improvemen in the fture?
4. Perhaps make the winner of each category in the leaderboard bold?
5. GLM 4.6 missing explanation rate with tools.
6. Maybe add cost too ? SWE bench has a cost field.
7. For GLM / Qwen perhaps also mention inference stack + versions ?
