Gemini Carbon 💎, ship less JavaScript 📦, what frameworks cost AI agents 🧮

Ship less JavaScript in Next.js with your AI agent (3 minute read)

Next.js 16.4 adds an agent skill that uses Turbopack's module graph to find unnecessary client JavaScript, including eager imports, duplicate dependencies, and missed tree shaking. Vercel reports removing or deferring nearly two megabytes of compressed JavaScript across pages in v0 and vercel.com, with snapshot comparisons to verify each change.

Our AI Agent Executed the Same Successful SQL Query 254 Times (2 minute read)
