## Summary - Image attachments (PNG, JPEG, WebP, GIF) skip the document parser and go to a vision-capable Ollama model (`OLLAMA_MODEL_VISION`, default `gemma4:latest`). - The image is stored on the prompt. `PromptSerializer` returns `file_type` and base64 `image` so history can redraw it. - Unsupported image types and files over 8 MB return a websocket error and are not saved. - A later text turn does not reuse a previous image as a spreadsheet. Pairs with `chat_web_app` `feat/128-vision-image-prompt` ([#128](ai_ml_operations/chat_web_app#128)). ## Test plan - [ ] `manage.py test chat_backend.tests.test_vision chat_backend.tests.test_consumers.GraphNodeTestCase` - [ ] Send a prompt plus PNG over `ws/chat_again/` and confirm the vision model is called. - [ ] `GET conversation_details` includes `image` and `file_type` for that turn. - [ ] CSV upload still follows the document path.
