GitHub Copilot is GitHub's AI pair programmer, built into VS Code and the JetBrains IDEs. Its bring-your-own-key support includes a Custom Endpoint provider that speaks both the OpenAI and Anthropic API formats, so chat and agent mode run on the model you choose while inline code completions stay on GitHub's own models. Point it at Opper's compatible gateway and you get 700+ models on one key with a choice of EU or US hosting, and in VS Code it works even without a Copilot plan.
GitHub CopilotoninPaste this into your coding agent (Claude Code, Cursor, Codex, and more) and it will set up and build with Opper for you.
Claude Fable 5.1 runs on the routes below. Route only to EU providers when your data has to stay in Europe.
