GitHub Copilot CLI adds BYOK models

This is the kind of feature that quietly matters more than a flashy model launch: it makes Copilot CLI far more model-agnostic and easier to fit into real developer stacks.

• –Teams can swap providers without rewriting their terminal workflow, which lowers lock-in and makes experimentation much cheaper
• –OpenAI-compatible support is the big unlock, since it covers a wide range of hosted, self-hosted, and open-source model backends
• –Azure OpenAI and Anthropic support makes the CLI easier to adopt in regulated or vendor-standardized environments
• –Local model support signals that GitHub is treating terminal agents as infrastructure, not just a fixed hosted experience
• –For power users, this brings Copilot CLI closer to the broader “bring your own model” agent ecosystem that tools like OpenRouter and Ollama helped normalize
