Iterating Towards LLM Reliability with Evaluation Driven Development

Dosu, an AI teammate designed to help develop, maintain, and support software, was created by Devin Stein, CEO of Dosu, to alleviate the burden on open source software maintainers and developers who often spend a significant portion of their time on non-coding tasks. Dosu uses Evaluation Driven Development (EDD) to ensure reliability and performance, continuously iterating on its logic and models to handle various scenarios effectively. As Dosu's usage grew, monitoring its activity and identifying failure modes became challenging, leading to the integration of LangSmith, a tool that provides enhanced monitoring capabilities through its SDK, allowing for detailed tracing and evaluation of Dosu's performance. LangSmith's features, such as customizable metadata tracking and advanced search functionalities, have enabled Dosu to identify and address unforeseen failure modes, thus improving its service. The collaboration between Dosu and LangChain, facilitated by LangSmith, creates a synergistic cycle where improvements to Dosu reduce maintenance burdens, allowing for more focus on feature development, ultimately enhancing both platforms.
