DeepSeek releases V4.1-Flash, says it outperforms flagship V4-Pro

DeepSeek released DeepSeek-V4.1-Flash and says it beats its larger DeepSeek-V4-Pro on performance, cost, speed, and total runtime. Starting Sept. 14, V4-Pro API requests will be served by V4.1-Flash and billed at Flash’s rates until V4.1-Pro launches, while V4-Flash and the August experimental vision model are retired. The change shifts default routing and pricing to the smaller mixture-of-experts model, with V4-Pro becoming a temporary backend rather than the billed endpoint.
