Google's Gemini 4 Argon autonomously optimizes 200K-line codebase

By PulseAugur Editorial · [1 sources] ·

Google utilized its Agent Development Kit with Gemini 4 Argon to autonomously optimize a substantial 200,000-line codebase over an 11-hour period. The AI agent successfully merged two pull requests, resulting in approximately 40% reduction in session overhead and a 21% decrease in cold imports. However, four other pull requests were rejected due to concerns regarding reliability and maintainability. AI
