vscode-unify-chat-provider

Why we included this project

VS Code users who are tired of paying for several separate AI subscriptions can point Copilot Chat at the providers they already have. The extension hooks into the editor's Language Model API and handles chat, code completion, and commit messages, so a Claude Code or OpenAI Codex quota can do the work instead of a fresh API key. Setup is mostly one click, with parameter presets for a couple hundred models, and there's a manual path for providers that aren't in the preset list. It also includes FIM and next-edit-prediction completion, which means it can replace the built-in autocomplete, not just the chat pane.
