DeepSeek upgrades V4.1-Flash and keeps the same API price
On Oct. 17, 2026 DeepSeek upgraded V4.1-Flash to V4.1-Flash-1017 on its website, app, and API. Callers still use the name deepseek-flash, and DeepSeek says the price is unchanged. The company says the checkpoint improves reasoning, coding, agent, and visual benchmarks while shortening task time and output length, and it posted MIT-licensed weights. Its own table lists Terminal-Bench 4.0 at 42.3, up from 31.2, and DeepSWE v1.1 at 77.0, up from 74.2.
