## Summary

Artificial Analysis says it worked with the CritPt authors to finalize the CritPt v2 grading server, which will be available through its API tomorrow. The authors' robustness fixes were incorporated as v5.0.1 of the Artificial Analysis Intelligence Index. After regrading all models, most scores rose slightly, but frontier model rankings are unchanged and no score moved by more than 1 point.

## Post

We’ve worked with the CritPt authors to finalize the CritPt v2 grading server and will be making this available to the community via Artificial Analysis’ API tomorrow. As part of this process the authors made robustness improvements to the grading server logic, which we have incorporated as v5.0.1 of the Artificial Analysis Intelligence Index

We regraded every model and observe small score increases for most models. Intelligence Index rankings are unchanged among frontier models, with scores moving by at most 1 point.

Thanks to @MiniHui_zhu, @MinyangTian1 and the rest of the CritPt team for their ongoing collaboration
