What GitHub Copilot's Usage-Based Billing Means for Zed Users

GitHub is transitioning Copilot Chat from a request-based billing model to a token-based billing system using GitHub AI Credits, which will impact users of Copilot Chat in the Zed IDE by metering their usage differently. While this change does not affect edit predictions like code completions and Next Edit suggestions, it does apply to various Copilot Chat model activities such as agent turns, inline assists, and commit-message generation. Users who frequently use Copilot Chat, particularly with agents, may see an increase in costs. GitHub provides a preview tool for users to estimate their potential expenses under the new pricing structure and advises team managers to set budgets to prevent overages. Zed users have the flexibility to switch to other model providers if needed, as Zed supports multiple options including hosted models, subscription services like ChatGPT, personal API keys, and local models.
