In March 2026, Liam Murphy focused on backend development for the phidatahq/phidata repository, addressing a critical bug in Azure OpenAI integration. He implemented an override of the __deepcopy__ method in Python to ensure that async client references were preserved during deep copies of Azure OpenAI models, preventing authentication errors in reasoning flows. This approach aligned with LiteLLM patterns and maintained compatibility with existing usage. Liam validated his changes using code formatting and validation scripts in a clean environment. His work improved the reliability of API integration and reduced downstream debugging for Azure OpenAI usage in production reasoning pipelines.
