Pull Request Overview

This PR updates documentation to use a new cross-reference linking syntax (@[...]) for Python API references.

• Migration of hardcoded API links to the new automated linking system
• Update of Anthropic model references throughout documentation

This code example shows both the new and deprecated approaches in a single block without clear separation. Consider splitting this into a 'before/after' comparison or adding clearer inline comments to distinguish which pattern is correct versus deprecated.
