GitHub has announced new pricing and usage limits for its Copilot AI coding assistant, effective May 5, 2025. Users can now access 'premium requests' for advanced AI models like Anthropic’s 3.7 Sonnet, which will be capped based on subscription level. The Copilot Pro tier offers 300 premium requests per month for $20, while Business and Enterprise users will receive 300 and 1,000 requests, respectively. Additional requests can be purchased at $0.04 each. This move reflects rising computing costs but highlights Copilot's significant contribution to GitHub's revenue growth.
