Code Mode revolutionizes how you use tools with your LLM in your apps. It's faster, uses less context, and is more accurate. What's not to like?

TanStack AI Code Mode is a new approach to LLM tool calling that replaces multiple round-trip tool invocations with generated TypeScript code executed in an isolate (QuickJS, Node, or Cloudflare Workers). Instead of 4 LLM round trips and 9.8KB of context for a simple query, Code Mode achieves the same result in 2 calls with 1.7KB of context and 3x faster execution. An additional 'skills' layer lets the LLM persist and reuse generated TypeScript functions, reducing subsequent calls further. The system also supports connecting directly to databases and dynamically generating UI components via code.
