Worked on enhancing model metadata management in the BerriAI/litellm repository by implementing a feature that adds display_name, model_vendor, and model_version fields to the model schema. This update improved the clarity and organization of model information, supporting better discoverability and governance within the system. The approach focused on robust API design and thoughtful data modeling, using JSON to structure and manage the new metadata. By extending the metadata schema, the work laid a foundation for future analytics and downstream integrations, enabling more consistent UI display and vendor attribution. The contribution addressed catalog clarity without introducing bug fixes during the period.
