The GPT Vision API (GPT-4o, GPT-4V) is a multimodal engine: It processes images, documents, and charts, delivering advanced visual reasoning via the Chat Completions endpoint.

This is your direct path to multimodal AI: The GPT Vision API, powered by models like GPT-4o, integrates image understanding into the familiar Chat Completions API. You send visual inputs (PNG, JPEG, or Base64 data) alongside your text prompt, and the model analyzes them. Use cases are broad: object detection, complex chart and dashboard analysis, OCR for document parsing, and interpreting UI flows. This capability streamlines image-to-text tasks, eliminating the need for separate computer vision pipelines, all within a single, powerful API call.

### [FINN – Parsing complex invoices with Vision API and GPT4](https://munich.aitinkerers.org/talks/rsvp_9d12SMNubpU)

FINN has 20.000 cars on the road that all want to be serviced and inspected. This happens in hundreds of different workshops all across the country. Every month, we receive more than 1,000 invoices that tell us what car was serviced, at which mileage, at which date, and with which costs. All invoices must be read out for this data. Because we have hundreds of different invoice layouts, conventional invoice parsing software failed. With the GPT Vision API preview and GPT 4, however, we were able to extract this unstructured data with ~85% accuracy automatically, saving us 15-20 working hours a month.
