Notes
- Request uses
POST /api/v1/chat/completionswithmodalities: ["image","text"]. - Images are returned as base64 data URLs in the assistant message; the script decodes and writes to disk.
- For edits/inpainting, include
messageswith both text and image-URL content parts — the script currently supports text-only prompts.
