# MiCRo Expert Routing Visualizer (Gradio)

This demo visualizes how modular language models allocate computation across specialized experts—Language, Logic, Social, and World—when processing a given prompt.
Each expert corresponds to a cognitive domain inspired by human brain networks. Enter a prompt to see how tokens are dynamically routed across modules, revealing the model’s internal reasoning structure.

## How it works
- Choose a model (dropdown) or type a custom model id.
- Enter a *User prompt*. Optionally add an *Assistant prompt*; if provided, the app concatenates them as:

  ```
  User: <user text>
  Assistant: <assistant text>
  ```

- When the prompt fails, the demo falls back to "mock data", which generates deterministic, pseudo-random percentages from the prompt.  

### Backend contract
`get_expert_routing(model_id: str, prompt: str)` must return 4 values (percentages) for the experts in this fixed order:
`["Language", "Logic", "Social", "World"]`
or a dict with those exact keys.
