GitHub Copilot 新模式：按量計費懲罰重度用戶

github officially transitioned copilot billing to a consumption-based model on june 1, 2026, charging users per credit (1 cent) based on variable token rates for models like chatgpt-5.2 ($14/million output tokens) and claude sonnet 4.6. while monthly subscription tiers remain ($19-$39), users report exhausting monthly allocations rapidly; one user noted nearly half a 7,000-credit allowance vanished in a single day. this pricing structure replaces the previous unlimited usage 'loss leader' model with a scheme that directly passes on high inference and compute costs to customers. enterprises must now implement strict usage governance or negotiate custom enterprise agreements to prevent budget overruns on coding assistants.
