DeepSeek-V4-Flash official API enters public beta with stronger agent skills

DeepSeek-V4-Flash 更新

The DeepSeek-V4-Flash official API is in public beta. The call method is unchanged, and setting the model name to deepseek-v4-flash uses the latest version. DeepSeek says its agent benchmark results far exceed V4-Pro-Preview, with Terminal Bench 2.1 at 82.7 and NL2Repo at 54.2. The model natively supports the Responses API and is specifically adapted for Codex.

Why it matters: DeepSeek-V4-Flash natively supports the Responses API and is adapted for Codex, while existing API calls stay the same.
