[Bug] Anthropic API Error: Image dimensions exceed max size in multi-image requests

Resolved 💬 3 comments Opened Nov 9, 2025 by michiglueck Closed Nov 12, 2025

Bug Description
I get this error even when I just send a text message now, the images were not special either: ⎿ API Error: 400 {"type":"error","error":{"type":"invalid_request_error","message":"messages.18.content.1.image.source.base64.data: At least one of the
image dimensions exceed max allowed size for many-image requests: 2000 pixels"},"request_id":"req_011CUwN6c6rsPmwqeLiuEovd"}

In the next terminal it said my usage limit was reached and its switching models, maybe thats the reason.
Also please add an option to chose approval mode because whenever it asks me for the first time and I allow everything, that change request still fails.
