GitHub Copilot
GitHub Copilot coding extension — the world's most widely used AI coding assistant, native to VS Code; usage-based AI Credits billing across all plans since June 2026
Core models
OpenAI's flagship and the most powerful GPT variant in Copilot—suited to complex multi-step reasoning, large-scale refactors, and long debug chains; uses long-context pricing beyond 272K input tokens.
Versatile flagship balancing speed and capability; handles the vast majority of everyday coding scenarios within 272K context—a strong cost-effective pick for chat and agent workflows.
A faster, lighter variant of GPT-5.4 with lower Credits cost—recommended for quick Q&A, completion-linked interactions, and high-frequency small tasks where latency matters.
The lightest GPT model in Copilot—minimal Credits per request, suited to high-volume low-complexity code comprehension and text generation so lightweight calls don't drain your premium-model budget.
The flagship Codex successor optimized for coding—strong on code generation, function comprehension, and API-call patterns; Copilot's go-to pick for intensive code-centric workflows.
Additional core model names still appear above, with full details on the latest official page.

Quota
Notes
- 1 AI Credit = $0.01 USD; base credits are fixed 1:1 to your subscription price, while the flex allotment is a variable add-on that adjusts over time; usage beyond the full allowance bills automatically at per-token model rates.
- Monthly Pro/Pro+ subscribers migrated automatically to usage-based billing on June 1, 2026; annual subscribers stay on PRU-based billing until expiry and then move to Free, or can convert to a monthly plan before expiry with prorated credit for the remaining annual value.
- Business ($19/seat) and Enterprise ($39/seat) pool their credits at the organization or enterprise level rather than isolating per individual; admins can set a budget cap and monitor usage in real time via the dashboard.
