+### Choosing an OCR Model
+
+The **Model** selector (next to the Mode selector) chooses which backend runs the OCR:
+
+- **DeepSeek-OCR (local GPU)** — the default. Loaded lazily on first use. Supports
+  every mode including grounding/bounding-box modes (Find), plus the Advanced
+  Settings (base size, crop mode, etc.).
+- **Ollama models** — any vision model pulled on your Ollama host and listed in
+  `OLLAMA_MODELS` (e.g. `glm-ocr`, `llama3.2-vision`). These run remotely on the
+  Ollama server. They return **plain text only**: bounding boxes are not produced,
+  so grounding modes (Find) and the DeepSeek-specific Advanced Settings are ignored
+  / disabled when an Ollama model is selected.
+
+Setup for Ollama models:
+
+```bash
+# On the machine running Ollama
+ollama pull glm-ocr
+ollama pull llama3.2-vision
+
+# Point the backend at it (in .env), then restart
+OLLAMA_BASE_URL=http://host.docker.internal:11434
+OLLAMA_MODELS=glm-ocr,llama3.2-vision
+```
+
+`GET /api/models` returns the registered models and their capabilities; the UI
+populates the selector from it. The model used for each job is stored on the job
+record (`ocr_model`) and shown in the Browse Jobs view.
