V4.1 Flash 开放 Search/Fetch API，每千次 0.75 美元
评论认为真正重点是 DeepSeek 开放第一方搜索与抓取 API，每千次 0.75 美元、与模型共用密钥，10 月 31 日前在 Harness/Claude Code/Codex 内免费，可能挤压 Tavily、Exa、Firecrawl 等中间层。
DeepSeek just shipped V4.1-Flash-1017 and everyone's staring at the 77.0 DeepSWE score beating Opus 5. wrong number. the real story is the other half of the announcement: DeepSeek opened its Search and Fetch APIs to everyone today. first-party web search + page fetch at $0.75 per 1k calls, behind the same API key as the model. free inside Harness / Claude Code / Codex until Oct 31. think about who that kills. Tavily, Exa, Firecrawl — the whole "we wrap a search engine for your agents" middleware layer. their entire moat was being the web plug agents reach for. now the cheapest frontier lab ships the web layer natively, at commodity pricing. the pattern: first DeepSeek ate the model margin. now it's eating the tooling margin. the agent stack keeps collapsing into whoever owns the model, and every middleware layer should be looking over its shoulder. (benchmarks are DeepSeek's own table, salt accordingly. the API pricing is real and it's live.)
