DeepSeek Documents GitHub Copilot Chat for V4

Checked on June 14, 2026: DeepSeek's official GitHub Copilot integration page now documents a VS Code extension that adds DeepSeek V4 Pro and Flash to Copilot Chat, keeps agent mode, tool calling, skills, and MCP, and adds an optional vision proxy path.

What we verified on June 14, 2026

  • DeepSeek now has an official GitHub Copilot integration page in its API docs for a VS Code extension called DeepSeek V4 for Copilot Chat.
  • That official page says the extension adds DeepSeek V4 Pro and DeepSeek V4 Flash directly into the GitHub Copilot Chat model picker.
  • The same official page says users keep Copilot's agent mode, tool calling, skills, and MCP while routing model work to DeepSeek.
  • DeepSeek also documents optional thinking-effort controls with None, High, and Max choices inside the model picker.
  • The same page documents an optional vision-proxy path: when a screenshot is dropped into chat, another installed Copilot model can describe the image before forwarding text to DeepSeek, because DeepSeek V4 itself is text-only.
  • DeepSeek's English homepage still points its public social anchor to @deepseek_ai, which remains the safest official X-account confirmation even though the X page itself is not safely crawlable here.
