1278If a single API request contains more than 20 images, a stricter per-image dimension limit applies to every image in that request. All `image` blocks in the request count toward this threshold, including images from earlier conversation turns that you resend and images nested inside `tool_result` content (for example, screenshots returned to the computer use tool). On Amazon Bedrock and Claude Models on Google Cloud (Google managed), document blocks such as PDFs also count toward this threshold. Images exceeding the stricter limit are rejected with an `invalid_request_error` whose message references “many-image requests” and states the current limit in pixels. To stay under the limit on all platforms, either resize each image so that neither dimension exceeds 3,000 px, or keep the request to 20 or fewer image and document blocks.
