    The DeepSeek API uses an API format compatible with OpenAI/Anthropic. By modifying the configuration, you can use the OpenAI/Anthropic SDK or softwares compatible with the OpenAI/Anthropic API to access the DeepSeek API. | PARAM | VALUE | | --- | --- | | base_url (OpenAI) | `https://api.deepseek.com` | | base_url (Anthropic) | `https://api.deepseek.com/anthropic` | | api_key | apply for an API key | | model(1) | `deepseek-v4-flash` `deepseek-v4-pro` | (1) The `deepseek-v4-flash` model has been updated to DeepSeek-V4-Flash-0731, and the `deepseek-v4-pro` model has been updated to DeepSeek-V4-Pro-0813. The calling method remains unchanged — simply use `deepseek-v4-flash` or `deepseek-v4-pro` to access the latest version. ## Integrate with Agent Tools​ The DeepSeek API is supported by many popular AI agent and coding assistant tools. If you use tools like Claude Code, GitHub Copilot, or OpenCode, you can use DeepSeek as the backend model directly — no code required. See the Agent Integrat

    DeepSeek V4 Pro 0813 quietly releasedHN

    To meet the demand for Codex, our API now supports the Responses API format, with the `base_url` being `https://api.deepseek.com`. With a simple configuration, you can use DeepSeek models in Codex. ## Integrating DeepSeek Models into Codex​ Please refer to Integrate with Codex. ## Calling DeepSeek Models via the Responses API​ `# Please install OpenAI SDK first: `pip3 install openai`from openai import OpenAIclient = OpenAI(api_key="<your DeepSeek API Key>", base_url="https://api.deepseek.com")response = client.responses.create( model="deepseek-v4-flash", instructions="You are a helpful assistant.", input="Hi, how are you?",)print(response.output_text)` ## Streaming​ Set `stream: true` to receive the response as a sequence of semantic server-sent events (SSE). Each event carries an `event` field indicating the event type, and a monotonically increasing `sequence_number`. The stream ends with a `response.completed` / `response.incomplete` / `response.failed` event — there is no `data: [D

    DeepSeek V4 Pro 0813 (on OpenRouter)

    DeepSeek V4 Pro 0813 (on OpenRouter) The latest DeepSeek Pro model is now available, via API only. I had to link to OpenRouter because DeepSeek don't have any obvious announcement page for their new model. I haven't been able to confirm if they plan to release the open weights, but given the weights are available for both April's deepseek-ai/DeepSeek-V4-Pro and July's deepseek-ai/DeepSeek-V4-Flash-0731 it seems likely. Interestingly I got very different looking pelicans for the three different reasoning levels of low, medium, and high. I've not noticed this kind of difference from any other model: Low: Medium: High: In terms of benchmarks... as far as I can tell those were released to the Official DeepSeek WeChat Group, then copied and pasted into a post on Reddit which was deleted by the moderators for being "low-effort", then copied into this ASCII-art table on Hacker News .

    刚刚，DeepSeek V4 Pro正式版发布！

    出乎所有人的预料。 周三晚间，DeepSeek 突然搬出了全世界都在期盼的 V4 Pro 大语言模型的正式版。 最先更新信息的是 DeepSeek API 文档，可见新模型被命名为 DeepSeek-V4-Pro-0813 。此外当前官方仍未调升 API 的使用价格。 文档链接：https://api-docs.deepseek.com/quick_start/pricing/ 在 AI 社区，已有一些正在使用大模型 API 的用户表示，调用的 V4 Pro 思维链风格已经出现变化。 同时，这张跑分图也开始在广为传播，可以看出，V4 Pro 在 Agent 相关评测表现上几乎可以与 Claude Fable 5 这些顶级模型媲美。 有意思的是，DeepSeek 这波上新，直接撞车了马斯克的 Grok 4.6！明天大家有的玩了！ 此前我们收到了一个坏消息：随着 DeepSeek V4 Flash 正式版的发布，全球用户大量使用，DeepSeek 官方 API 近期已经多次遭遇性能下降的问题。因为推理算力不足，DeepSeek 最近正在酝酿一波涨价。 不知 V4 Pro 正式版能否满足大家对于性价比的需求？ 另外，V4 Pro 已经发布！DeepSeek 的 Harness 还远吗？明天会不会有更多惊喜呢？期待一下吧。

    刚刚，DeepSeek V4 Pro正式版发布，多项对标Fable 5 Jay 2026-08-13 11:54:01 来源： 量子位 现在调用V4 Pro，能直接用上完全体 Jay 发自 凹非寺 量子位 | 公众号 QbitAI 家人们，火星撞地球了。 刚刚，DeepSeek V4 Pro正式版，发布了！！ 太离谱了，看了眼Benchmark，这是 直接要和Fable对标啊。。。 HLE、Terminal Bench、Cybergym、DeepSWE……Agent能力几乎全方位碾压Opus 4.8，无限逼近Fable 5，甚至有些榜单都反超了。 看到没，这就是后训练的威力！！！ DeepSeek V4 Pro正式版 可惜，官方博客还没发，不能继续一探究竟。 但API平台是先一步更新了，现在调用V4 Pro，能直接用上完全体， DeepSeek-V4-Pro-0813 。 价格这块依旧很能打，基本和之前的Pro预览版保持一致。 百万tokens输入 3元 ，命中缓存 0.025元 ，百万tokens输出则是 6元 。 我宣布，滑动变阻器再次进入「梁圣」周期。 但也不是没有坏消息。 网友实测后发现， CoT成山顶洞人了啊。。。 Need to identify as DeepSeek model. The system says You are DeepSeek, knowledge cutoff May 2025, current date Aug 2026. We need be honest. We are DeepSeek latest model? 虽然也能看懂啥意思，但反正也是彻底不言人语了，不影响意义传递的词全囫囵吞枣了。 这估计也是为了性能优化考虑，之前看过YouTube博主分析， GPT隐藏的思维链也是这个风格 ，说是「山顶洞语」可以大幅减少Token消耗。 但代价吧，就是写作估计是寄了。。。 这也是Agent狂飙时代的大趋势吧，一切能力都在优先为Coding让位。 但至少，在Coding方面，V4 Pro正式版完成了它该做的。 国产开源阵营，又出现了一个紧逼闭源的超级模型。 这一次，它来自DeepSeek。 One More Thing 说实话，好久没有看到这么激动人心的场景了。 深夜吭哧吭哧写完稿的我，如今仿佛看到原子弹爆炸，瘫软在椅，久久不能动
