Worked on the openai/openai-cookbook repository to update the function calling examples for compatibility with the latest GPT models, specifically gpt-5 and gpt-4.1. Focused on enhancing developer onboarding by revising code samples and documentation in Jupyter Notebook and Python, ensuring that examples accurately reflected current model capabilities. Centralized updates across key sections of the cookbook to maintain consistency and reduce confusion for developers integrating with OpenAI APIs. Emphasized clear documentation and robust API integration practices, resulting in a more maintainable and accessible resource that supports developers in leveraging new AI/ML features with up-to-date guidance and examples.
