Worked on the ml-explore/mlx-lm repository to enhance API reliability and developer experience by addressing a key documentation and type hint issue in the batch_generate function. Focused on backend development using Python, the work involved correcting the prompts parameter type to List[List[int]] and updating the corresponding pydoc to match the function signature. This targeted fix improved interface clarity, reduced integration risk, and streamlined onboarding for downstream users. By aligning documentation with actual code behavior, the update ensured more predictable API usage and minimized potential confusion for developers integrating with the system, reflecting a detail-oriented approach to API development and maintenance.
