Summary: GitHub Copilot transitioned all plans from flat-rate premium-request billing to token-metered GitHub AI Credits on 2026-06-01. Each plan includes a monthly allotment: Pro 1,500 credits ($15), Pro+ 7,000 credits ($70), Max 20,000 credits ($200). Code completions and Next Edit Suggestions remain outside credit metering. Agentic sessions and agent-mode interactions consume credits based on actual token throughput; developers report single agentic sessions exhausting $30 to $40 in credits, and Pro+ monthly bills jumping from $39 to $750 or higher. The fallback to a cheaper model on credit exhaustion was removed. Microsoft confirmed no plans to revert the billing model.
Why it matters: Teams budgeting under the previous flat-rate model face unpredictable cost increases; organizations should configure GitHub credit spending limits and audit per-developer consumption before the next billing cycle.
