DeepSeek V4.1 Flash 1017 vs GPT-6 Astra: Same Score for 9 Cents a Test
DeepSeek updated V4.1 Flash on 17 October, so I ran the 1017 snapshot through OpenRouter at high effort on release day. It scored 7.50 on eight tests, second of 18 models, 0.01 behind GPT-6 Astra and ahead of Opus 5.5 and Sonnet 5.5. All eight tests cost 71 cents on my OpenRouter bill, about 9 cents a test, against about $3.77 for Astra and $5.18 for Opus on the same tests. Visually, Opus and Sonnet are still ahead.
The results
The same scores as the leaderboard: a test that failed is left out of its run's score, not counted as zero. Time, tokens and cost cover each whole run, wildcards included.
Ranking
Quality v1 over measured non-wildcard pages. Different workloads: browse the outputs and coverage before comparing models.
Score against output tokens
Quality v1 against full-run tokens. Different workloads and hardware affect this comparison.
Output tokens include the model's thinking. Like the time, tokens and cost table, it counts every test the model took, wildcards included. A hollow dot is not an exact count: some tests reported none, or the count was worked out from the length of the output. The score axis is zoomed to the data.
Score against time
Quality v1 against full-run time. Different workloads and hardware affect this comparison.
Time is how long the model took to answer, added up over its tests; judging is not counted. Like the time, tokens and cost table, it counts every test the model took, wildcards included. A hollow dot is a lower bound: some tests have no time recorded. The score axis is zoomed to the data.
Where each model is strong and weak
One row per model, one column per test and per scoring criterion.
