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.
Based on the README, here's a deeper technical summary: Core to WilmerAI is a **node-based workflow engine** defined in JSON that performs conversational-context-aware routing by analyzing entire message histories rather than isolated prompts. Workflows are composable and multi-layered—each routing decision can trigger specialized sub-workflows that orchestrate multiple LLMs, external APIs, custom scripts, and tool calls in sequence, with the entire multi-step process appearing as a single API call to the client. Recent updates enable single-instance multi-user deployments with request queuing, per-user/per-API-key file isolation with optional Fernet encryption, and automatic memory condensation for long conversations.
