v0.4.0 · 1mo ago
A routing layer that selects or combines LLMs and compute backends per request based on configurable policy, exposed behind one OpenAI-style API.
Why you might care
Useful if you run agents or apps across several models or backends (local, private, cloud) and want a policy to pick the model per call for quality, latency, cost, or data-location constraints. It sits in front of existing inference endpoints, so the agent harness keeps its own loop and tools.
