The context window update to 128k looks correct and aligns with the DeepSeek API documentation. Consider adding a comment referencing the API docs URL (https://api-docs.deepseek.com/quick_start/pricing/) for future maintainers.

Also, this capability update might warrant a changelog entry so users know about the increased context window.
