 **Want a clean slate**
 `make super-clean` stops everything and **deletes all volumes** database, uploads, and downloaded model weights. Only use it when you intend to wipe all local data.
 
+## AI Model Selection
+
+FireForm allows you to choose which AI model to run during form extraction directly from the dropdown in the frontend "Fill Form" UI.
+
+The supported recommended models are:
+- `qwen2.5:1.5b` (default, lightweight)
+- `qwen2.5:3b`
+- `qwen2.5:7b`
+- `llama3.2:3b`
+- `mistral:7b`
+
+If you select a model that is not yet installed (pulled) in your local Ollama instance, the app will automatically request the backend to download it via the `POST /api/v1/forms/pull` endpoint. During installation, form submission is temporarily disabled, and status progress is displayed. Once downloaded, the model is cached in Ollama's Docker volume for future use.
