Otterflow

Otterflow is an intelligent LLM routing platform that uses a custom Bandit Reinforcement Learning algorithm to dynamically route queries to the best available language model at runtime.

Rather than always calling the most expensive model, Otterflow evaluates three axes — accuracy, cost, and latency — and learns over time which model performs best for which type of query. The result is dramatically lower inference costs with no sacrifice in quality.

The platform handles multi-provider orchestration (OpenAI, Anthropic, Gemini, local LLMs) and is designed to be drop-in replaceable with minimal configuration.
