deepseek-v4-for-copilot

Why we included this project

If you already work inside GitHub Copilot Chat but want DeepSeek's pricing and 1M-token context without abandoning your usual setup, this extension is worth a look. It puts DeepSeek V4 Pro and Flash into the model picker you already use, so agent mode, tool calling, and the rest of Copilot's stack keep working on the new model. You bring your own API key and pay DeepSeek directly, with the key stored in the OS keychain rather than on disk. A nice touch is vision proxying: since DeepSeek V4 can't read images, the extension routes anything you drop into chat through another Copilot model you already have, then feeds the description back to DeepSeek. For individuals or small teams who want to test DeepSeek on real coding tasks without learning a new chat interface, it's a low-friction way to compare models mid-conversation while keeping history intact.
