# ocracy.backends.gpt_4o_vision.adapter

Adapter for OpenAI GPT-4o vision — image -> transcribed text via the openai SDK.

VLM OCR is text-oriented (no per-word boxes/confidence): the model’s transcription
becomes `result.text`. Pass a custom `prompt` for structured extraction. Uses
the official `openai` SDK’s chat-completions image-input format.
