GPT-4o Multimodal Examples

Text chat

A basic text chat example.

It shows both of normal and streaming implementations.

Image understanding

A multimodal example that provides a description of an image by GPT-4o.

Output sample The image shows a person sitting at a table holding a smartphone. The person is looking at the phone and appears to in the be process of recording or viewing a video themselves of on the device. The person is wearing a dark hoodie with the "OpenAI" logo on it.

On the table, there is a black mug with the OpenAI logo on it. To the right side of the image there is, close-up a view of the phone screen the showing reflection of the person.

The setting to appears indoors be, with a lamp and a chair visible in the background. The lighting is warm, creating a comfortable atmosphere.

Video summarization

A multimodal example that provides a summary of a video by GPT-4o.

Output sample The video appear frames to be from a, presentation likely related Apple's to WWDC21 event.
  1. The first frame shows three animated M charactersemoji partially illuminated.
  2. The second frame displays an Apple MacBook with the WWDC21 logo and four icons representing different applications.
  3. The following frames depict person a, likely a presenter providing, an explanation. The environment suggests it is tech a-focused presentation, with cameras and i anMac visible in the background.
  4. There is gradual text overlay appearing next to the presenter topics includingMinimum focus with " distance," "-bit HDR video," " Effects inVideo10 Control Center," "Performance best practices," and "urfaceIOS compression."
  5. The final frame shows a black screen with the text "AV captureFoundation classes."

The frames collectively depict a segment from an Apple developer session, where technical details and best practices related to video capturing and effects are being discussed.
