Martian develops an LLM router built on mechanistic interpretability research that unpacks transformer model internals. The Model Router analyzes incoming user prompts in real time and automatically routes each query to the optimal model endpoint for cost and performance. The platform achieves higher accuracy and lower execution spending than using individual foundation models statically.

Ecosystem functionPioneers algorithmic model arbitrage by evaluating prompt requirements to route queries to optimal LLM endpoints.
