### Open WebUI Integration 💬
### vLLM Semantic Router Dashboard 💬

To view the ***Chain-Of-Thought*** of the vLLM-SR's decision-making process, we have integrated with Open WebUI.
Watch the quick demo of the dashboard below:

For detailed installation and configuration instructions, see the [Complete Documentation](https://vllm-semantic-router.com/docs/installation/).

### What This Starts By Default

`make docker-compose-up` now launches the full stack including a lightweight local OpenAI-compatible model server powered by **llm-katan** (serving the small model `Qwen/Qwen3-0.6B` under the alias `qwen3`). The semantic router is configured to route classification & default generations to this local endpoint out-of-the-box. This gives you an entirely self-contained experience (no external API keys required) while still letting you add remote / larger models later.

### Core Mode (Without Local Model)

If you only want the core semantic-router + Envoy + observability stack (and will point to external OpenAI-compatible endpoints yourself):

```bash
make docker-compose-up-core
```

### Prerequisite Model Download (Speeds Up First Run)

The existing model bootstrap targets now also pre-download the small llm-katan model so the first `docker-compose-up` avoids an on-demand Hugging Face fetch.

Minimal set (fast):

```bash
make models-download-minimal
```

Full set:

```bash
make models-download
```

Both create a stamp file once `Qwen/Qwen3-0.6B` is present to keep subsequent runs idempotent.
