An open, programmable decision layer for models and compute.

Route LLM requests to the best model for the task at hand.

LLMRouter: An Open-Source Library for LLM Routing

WilmerAI is one of the oldest LLM semantic routers. It uses multi-layer prompt routing and complex workflows to allow you to not only create practical chatbots, but to extend any kind of application that connects to an LLM via REST API. Wilmer sits between your app and your many LLM APIs, so that you can manipulate prompts as needed.

The minimal interpretable model router that learns & adapts to your agent workflows

Simple CLI tool for deterministic routing of queries between local and hosted LLM models

Production focused Self-harnessed LM runtime (RLM) that allows the LM to call its sub-lm with DSPy signatures. Define your inputs, outputs, and tools — the model handles its own control flow. Get fully interpretable trajectories and performance that scales directly with model improvements. Without context rot.

Harness LLMs with Multi-Agent Programming

brick is a smart AI Models router, based on complexity & capabilities extraction from the query to the models via proprietary spatial embedding algorythm
