·2026.04.19 05:15

Key point

In Copilot CLI, auto automatically selects the most efficient model.

Details

Copilot auto model selection in GitHub Copilot CLI has moved to General Availability (GA).

  • Available on all Copilot plans.
  • Using auto, Copilot automatically picks the most efficient model according to your plan and policies.
  • Current routing targets include GPT-5.4, GPT-5.3-Codex, Sonnet 4.6, Haiku 4.5, and others.
  • You can check directly in Copilot CLI which model auto used.
  • You can switch between auto and a specific model at any time as needed.
  • Admin model settings are still respected.
  • Billing is based on the premium request multiplier of the model auto selects, currently limited to models with 0x~1x multipliers.
  • Paid subscribers get a 10% discount on the model multiplier when using auto. For example, if a 1x model is selected, 0.9 premium requests are deducted.
