Discrepancy between the maximum number of images that can be attached to a chat and actual behavior

Converse API allows up to 20 image attachments, and it correctly displays an error when trying to attach more than 20 images on the chat screen.

> You can include up to 20 images. Each image's size, height, and width must be no more than 3.75 MB, 8,000 px, and 8,000 px, respectively.

While Claude is fine, Pixtral has a token-based limit rather than a limit on the number of images, Llama3.2 has a limit of 1 image (though this is not documented), and Llama 4 has an upper limit of 8 images, with an error being returned if this limit is exceeded.


(I haven't thought of a good idea about what to do.)

Start with packages/web/src/pages/ChatPage.tsx at the referenced line and compare its 20-image check with the Converse API behavior described in the issue. Review the linked Bedrock conversation-inference documentation and the reported Claude, Pixtral, Llama 3.2, and Llama 4 limits. Done means the chat behavior and displayed errors accurately reflect the applicable model limits.
