## quick start
```bash
cupel
```
opens a browser at `localhost:8042`
ships with example data (8 models scored by Claude Opus 4.6 on 8 prompts) — the dashboard is populated on first launch
- **LLM-assisted authoring** — describe what you want to test, an LLM drafts the prompt and 0–3 rubric
- **local + cloud** — oMLX, Ollama, LM Studio, SGLang, OpenRouter, Anthropic, OpenAI
- **configurable judge** — any model can score responses on a 0–3 rubric with reasoning
- **thinking model support** — separates `` blocks from answers, only judges the response
- **multi-turn + tool calling** — multi-step conversations with injected tool results
- **speed tracking** — tok/s and response times per model
- **auto-discovery** — probes known ports for local inference servers
