GitHub Deprecates GPT-4o in Copilot Chat, Recommends GPT-4.1
GitHub has phased out the GPT-4o model in its Copilot Chat feature as of August 6, 2025, shifting focus to GPT-4.1 for enhanced performance. The change affects ask, edit, and agent modes across IDEs, GitHub's website, and mobile apps, though GPT-4o remains active for code completions.
The transition, first hinted at in GitHub's May 8 changelog, reflects the company's push to integrate cutting-edge AI capabilities. Developers can discuss the update on GitHub Community, a hub for feedback and shared experiences.
This MOVE mirrors broader industry trends where AI advancements are rapidly adopted to maintain competitive edge. GitHub's decision underscores the relentless pace of innovation in developer tools.
