maximalize your AI ecosystem

Switch on the coding tools you already use, and maximal runs them on the models in your Copilot plan.

the tools you use
  • Claude Code
  • Codex
  • opencode
  • any Anthropic / OpenAI SDK
your Copilot models
  • Claude Opus 5
  • GPT-5.6
  • Gemini 3 Pro
  • …and more

Nothing new to set up. No second bill.

No new keys. Your tools think they're talking to Anthropic or OpenAI — your Copilot plan answers.

One plan covers every tool. Without maximal, each tool needs its own paid subscription — here, they all run on the Copilot plan you already have.
