Image Inputs and Vision Workflows
Multimodal models may accept text and images in one request, but support and image handling differ by model and provider. Images can be resized or tiled internally, and high-resolution analysis may cost more. Use images only when they add task-relevant evidence; avoid sending unrelated or sensitive images.
For image workflows, validate content type and size, remove unnecessary metadata where appropriate, check user consent and access, and store files securely. The model may miss small text, exact counts, or subtle visual details. For exact measurements or identity-sensitive tasks, use dedicated deterministic or human-reviewed workflows as appropriate.

Image workflow
Upload -> authenticate -> validate type/size -> secure storage
-> create provider-compatible input
-> model analysis -> validate response
-> display answer with uncertainty💡 Do not trust a file extension alone to establish file type. Use server-side validation and limit the model to the image data required for the task.
Key Takeaways
- Validate uploads and minimize sensitive image exposure.
- Choose model/image settings based on task needs.
- Use human review for high-impact visual judgments.
