Tom Pakeman developed advanced function calling and real-time evaluation frameworks for the openai/openai-cookbook repository over a three-month period. He built example notebooks and documentation to demonstrate reasoning-powered function calls, integrating external data sources and web search, and provided guidance on sequential and parallel tool usage. Using Python, Jupyter Notebooks, and Streamlit, Tom implemented robust error handling, persistent result storage, and interactive data visualization for API evaluation metrics. His work included a Streamlit-based results viewer for real-time metric comparison, improving feedback cycles and reliability. The deliverables provided production-ready references that accelerated onboarding and enabled data-driven API tuning for developers.
March 2026: Delivered a real-time evaluation framework for OpenAI API evaluations, including a Streamlit-based results viewer to compare metrics and inspect individual runs in real time. Implemented robust error handling, persistent result storage, and plotting capabilities for evaluation metrics. This work, supported by realtime evals types tooling and a dedicated results viewer (both co-authored), reduces feedback cycles, improves reliability, and enables data-driven API tuning. Key technologies include Python, Streamlit, data visualization, and collaborative tooling.
