DeepSeek V4 Pro 0813 leads with 71.1% among models released by Aug 2026

Best score per model as labs report them in their own cards. Labs pick their own settings, so these compare less cleanly than independent runs.

The newest model with a score here came out in Aug 2026, and nobody has reported a newer one. Among the 20 highest-ranked models on the capability index, these have no score yet:

  1. 1 DeepSeek V4 Pro 0813 71.1%
  2. 2 DeepSeek V4 Flash 0731 68.7%
  3. 3 DeepSeek-V4-Flash-Vision-Exp 63.6%
