GitHub has implemented monthly limits on its AI models, reflecting a broader industry trend towards monetization of AI services. Starting this week, users of GitHub Copilot face charges of $0.04 for excess requests. Copilot Pro users receive 300 monthly requests, while Business and Enterprise plans allow 300 and 1,000 requests, respectively. CEO Thomas Dohmke emphasized that this shift is necessary for sustainable AI business models, which could reshuffle budget strategies for enterprises.
