Langfuse has developed a Q&A chatbot to assist users in navigating their documentation, leveraging technologies like OpenAI's GPT-3.5-turbo for generating responses and Supabase for managing embeddings and storage. The chatbot utilizes embeddings of markdown files to perform similarity searches and generate contextually relevant answers, with a GitHub Action workflow updating the embeddings regularly. Langfuse monitors the chatbot's performance, usage, and quality through their own platform, capturing user feedback and tracing response processes to improve the system. By offering this tool, they aim to enhance user experience and demonstrate Langfuse's capabilities in observability and analytics, while all code remains open source on GitHub for transparency and community engagement.
