Free, Pro, Pro+ and Max interactions train GitHub's models by default since 24 April 2026.\n\n**Muse Code.** Muse Code runs with approvals and an OS sandbox on by default, per-host network approval, an append-only event log and a headless mode with documented exit codes. It is the only route to Muse Wonder Full. It is closed source with undated release notes and no free route, and subscriptions allow training on code unless Contributor mode is turned off.\n\n## Before you call either\n\n### GitHub Copilot CLI\n\n1. Pass `--deny-tool` for anything destructive. It wins over `--allow-all-tools` and `--allow-tool`\n2. Turn on the sandbox with `/sandbox enable` or `--sandbox`. It's off unless you opt in\n3. Turn off model training in Copilot settings on Free, Pro, Pro+ and Max. It's on by default since 24 April 2026\n4. Run 1.0.88 or later where enterprise policy matters. Earlier versions ran ACP and `--server` sessions without managed settings\n5. Use a fine-grained token with only the Copilot Requests permission in `GH_TOKEN` for CI\n\n### Muse Code\n\n1. Set `META_API_KEY` for headless runs. Browser sign-in isn't available in CI or for Meta Managed Accounts\n2. Gate on your own test command, not the exit code. `muse exec` returns 0 when the turn completes even if tests still fail\n3. Pass `--max-model-steps` on unattended runs so a stuck task can't loop\n4. Prefer `--disable-approval` to `--yolo` in CI so the sandbox stays on. On Linux the runner needs a working bubblewrap and a non-musl build\n5. Turn Contributor mode off in `/settings` before a subscription session touches private code\n\n## Questions\n\n### Which is better for AI agents, GitHub Copilot CLI or Muse Code?\n\nMuse Code scores 61.3 (C) on agent readiness against GitHub Copilot CLI's 57.6 (C), and leads in 3 of 7 scored categories.
