GitHub Copilot now offers models from OpenAI, Anthropic, Google, xAI, Microsoft and Moonshot AI, and the list changes almost every month. This guide reflects GitHub's documentation as of October 21, 2026 (Beijing time) and will be updated as models are added or retired.
How Copilot charges for models
Copilot usage is billed in GitHub AI Credits, where 1 credit equals $0.01. Each interaction is priced by the tokens it consumes at the chosen model's per-token rate, so a heavier model or a larger context window uses more credits. Copilot Free, Pro, Pro+ and Max include a monthly credit allowance; Copilot Business and Copilot Enterprise include per-user allowances pooled across the organization. Usage beyond the allowance is billed at the per-token rates below. On the plans page, Pro costs $10 per month, Pro+ $39 and Max $100, and Max includes $100 a month in AI Credits.
Premium request multipliers still exist only for Pro and Pro+ subscribers on an existing annual plan who stayed on request-based billing after June 1, 2026. For those subscribers, GitHub lists these multipliers for models still offered: Claude Haiku 4.5 at 0.33, MAI-Code-1.1-Flash at 0.25, GPT-5.3-Codex at 6, Claude Sonnet 4.6 at 9 and Claude Opus 4.8 at 27. Copilot code review carries a multiplier of 13 on that legacy billing.

Claude Opus 4.8 will stay available to individual subscribers on annual plans. For Copilot Business and Copilot Enterprise, the suggested replacements are enabled automatically unless an administrator has turned off default model enablement.
