DeepSeek V4.1 Flash 3,471 leads since September 2026
In use

Model solves recent Codeforces contest problems. An Elo-style rating is computed from simulated contest performance.

No standard public harness. Each lab's rating method differs, so numbers are not comparable across cards.

DeepSeek V4.1 Flash leads with 3,471 among models released by September 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 September 2026, and nobody has reported a newer one. Among the 20 highest-ranked models on the capability index, these have no score yet:
