Soon, your Copilot bill will tell you who burned the credits. It still doesn't show what they shipped with it. On June 1, 2026, GitHub switches every plan to usage-based AI Credits, with budget caps at the enterprise, cost centre, or user level. Useful. Stops at "which user." Copilot Budget fixes the next layer. Open source, MIT licensed. It reads what Copilot already logs locally and appends a receipt to every commit: feat: add OAuth2 login flow Copilot-Est-Cost: $0.41 Copilot-Model: claude_sonnet_4 1250/3800/1.00 The model line is `model input_tokens/output_tokens/premium_requests` — the exact units AI Credits will bill on after June 1. Already in your git history. `git log --grep="Copilot-Est-Cost"` across a branch = cost per feature. No external services, no telemetry. GitHub's budgets tell you WHO spent the credits. Commit trailers tell you WHAT FOR. Get both before the meter starts running. #OpenSource #DeveloperTools #FinOps #GitHubCopilot #AI
