Vision for text-only harnesses: paste an image and get structured JSON evidence covering OCR, layout and semantics.
Use cases
Vision & OCR
Let text-only agents inspect images, screenshots, diagrams and scanned pages.
Vision plugins give a text-only model a way to look. The strongest implementations do not just describe an image, they return structured evidence the model can reason over: extracted text with positions, layout regions, colour values, and crop coordinates it can request next.
Prefer plugins that treat images as ordinary tool calls instead of a special turn type, and check whether the vision backend is local, free, or requires your own key. For screenshot-heavy work, confirm that long images are tiled rather than downscaled into illegibility.
