🚀 @GoogleAI's Gemini 4 Argon is now generally available in GitHub Copilot.
What we learned from early testing ⬇️
• It solved more tasks than previous Gemini models on every coding benchmark, with its largest gains in Copilot CLI.
• It checks its work thoroughly, testing edge cases before it finishes.
Use Gemini 4 Argon for complex coding, agentic, and reasoning tasks. Find it in the GitHub Copilot app, CLI, and @code.
