We have just finalized the Chat and Language Model APIs that allow extensions to extend GitHub Copilot in VS Code.

We recently had a session at Microsoft Build on this topic:

If you have any questions feel free to comment and I will be happy answer questions.

In case you are using our provided language models, I suggest to start using GPT-4o, should be faster and better. Here’s the code snippet

const MODEL_SELECTOR: vscode.LanguageModelChatSelector = { vendor: 'copilot', family: 'gpt-4o' };
const [model] = await vscode.lm.selectChatModels(MODEL_SELECTOR);
