What's included

DeepSeek API is the OpenAI-compatible inference API from DeepSeek (platform.deepseek.com) exposing the DeepSeek-V4 family. Current models (verified in api-docs.deepseek.com, Aug 2026): deepseek-v4-flash (updated to DeepSeek-V4-Flash-0731) and deepseek-v4-pro (updated to DeepSeek-V4-Pro-0813); invoke by the alias and you hit the latest version. Endpoints: OpenAI-compatible at https://api.deepseek.com and Anthropic-compatible at https://api.deepseek.com/anthropic. Use the developer API key from platform.deepseek.com. This is the ChatGPT API / Claude API competitor for developers building on DeepSeek models (it is distinct from the DeepSeek Chat web assistant).
