Arize Phoenix: LLM and Agent Observability with - AI Build & Learn #11

Welcome to AI Build & Learn a weekly AI engineering stream where we pick a new topic and learn by building together. ​This event is about observability and evaluation for LLM and RAG applications with Arize Phoenix, an open-source AI observability platform for tracing, evaluating, and debugging LLM apps. ​We'll explore Phoenix tracing for LLM and agent workflows, running evals on captured spans (including Ragas metrics from last event), and how to use Phoenix to debug retrieval and generation issues in real applications. ​Some things to look up to get started: ​Arize Phoenix GitHub: https://github.com/Arize-ai/phoenix ​Phoenix docs: https://docs.arize.com/phoenix ​​​ Resources ​​​GitHub:…
