Klaatcode Routes Coding Tasks to Cheapest AI Model, Claims 82% Cost Reduction

Klaatcode is an open-source, terminal-based coding agent launched on July 17 that uses per-request model routing instead of locking users into a single AI model for an entire session. A small server-side router called Klaatu classifies each incoming request and dispatches it to one of five cost tiers — ranging from nano for trivial tasks to heavy for large refactors — escalating or de-escalating automatically based on complexity. The tool claims to deliver Claude Code-level accuracy at 82% lower cost, since only a fraction of coding tasks genuinely require frontier-model reasoning. Klaatcode also indexes project code into a knowledge graph with semantic search, which the developers say reduces token usage by 5 to 15 times compared to grep-based agents. Installed via npm, the agent requires no manual API key management and includes real-time cost transparency features that show users exactly how much the routing system is saving them.
