# Supra-Router-51M

A Gradio demo for [SupraLabs/Supra-Router-51M](https://huggingface.co/SupraLabs/Supra-Router-51M), an ultra-lightweight (51.7M parameter) multi-task infrastructure routing model. Given a user prompt, it predicts whether the request should be handled locally by an edge SLM or offloaded to a cloud frontier model, along with a structured analysis of the prompt's domain, complexity, math/code flags, and a justification.

The model wraps the query as `Task: {prompt}\nAnalysis: ` and performs greedy decoding to emit a deterministic, pipe-separated decision string. This Space runs entirely on CPU — the model is small enough for fast local inference.
