GitHub is making changes to its Copilot Individual plans, including pausing new sign-ups, tightening usage limits, and adjusting model availability, to ensure a reliable and predictable experience for existing customers. The changes are due to increased compute demands from agentic workflows, which have led to service quality degradation. Existing customers who are affected by the changes can cancel their subscription and request a refund. The changes include a new 7.5x multiplier for Opus 4.7 model usage.
