Platform developer GitHub has introduced far-reaching changes to its individual Copilot subscriptions due to rising usage and mounting pressure on its infrastructure. New subscriptions to the Pro, Pro+ and Student plans have been temporarily suspended, while existing users face stricter usage limits.
This decision stems from a sharp increase in the use of Copilot, particularly through agent-based workflows that run long-lasting and often concurrent tasks which require more computing power than initially anticipated. This heavy workload is putting additional strain on GitHub’s infrastructure and is leading to frequent limit breaches.
To ease this pressure, GitHub is temporarily restricting new subscriptions and enforcing existing limits more strictly. Pro subscribers can upgrade to Pro+ for higher limits. In addition, users receive notifications in Visual Studio Code and the Copilot CLI when they are approaching their usage limits, giving them greater insight into their consumption.
The availability of AI models is also changing. Certain Opus models are being removed from Pro subscriptions and partially restricted to Pro+, while older variants are being fully phased out, shifting functionality towards more expensive tiers.
GitHub acknowledges the impact these changes may have, but stresses the need to balance performance, cost and scalability. In some cases, individual requests exceed what users pay for their subscriptions, which jeopardises the quality of service. The measures are intended to prevent a deterioration in Copilot’s capabilities.
Challenges for the entire sector
According to The Register, broader industry trends are contributing to this situation. Demand for computing power is outstripping available capacity, with consequences for the entire AI sector. Earlier measures, such as ending free trial periods due to abuse, further underline these challenges.
The Register also points to a possible structural issue in Copilot’s pricing model. Some intensive AI requests cost GitHub more internally than users pay through their subscriptions, suggesting a need for adjustments towards usage-based pricing models.
GitHub has recently introduced weekly usage limits in addition to session limits. While session limits are designed to manage peak loads, weekly limits target total token consumption, which can quickly escalate with lengthy, complex tasks.
Users who exceed the limits can continue to use Copilot with adjustments, such as automatic model selection. Full access to specific models is restored once the usage period resets. Cancellation with a refund of recent charges is available to users who find the restrictions unacceptable.
