Motivation & Context

Copying the public Message example raises AttributeError because it calls Content.from_image_uri, which does not exist. The example stops before its serialization demonstrations.

Description & Review Guide

• What are the major changes? Use the existing Content.from_uri constructor with a concrete PNG URL and its media type.
• What is the impact of these changes? The complete documented example runs successfully, including mixed-content construction and both serialization round trips. Only the docstring changes; the runtime AST is unchanged. The actual public example failed before the change and passed on Windows Python 3.11.17 and Linux Python 3.13.16 afterward. Normal scoped repository hooks passed without changing the patch.
• What do you want reviewers to focus on? The example uses the existing public URI constructor and still demonstrates an image alongside text.

Related Issue

N/A - trivial change. This corrects a nonexistent method in a public example; the intended constructor already exists.

Model: gpt-5.6-sol

Overview

The PR updates only the Message docstring example, replacing a nonexistent constructor with the existing public Content.from_uri API. The constructor accepts the example's HTTPS URI and explicit media type, and existing tests plus direct execution confirm mixed-content construction, text extraction, and serialization round trips without changing runtime behavior.

Reviewed the supplied pull-request change set across correctness, security/reliability, architecture, and failure behavior.
No publishable findings remained after source verification for this scope.
