Arize Phoenix
Open-source RAG evaluation platform detecting hallucinations and measuring retrieval quality for financial pipelines.
Arize Phoenix is an open-source RAG evaluation and observability platform that detects hallucinations, measures retrieval quality, and tracks embedding drift in financial RAG pipelines. Hallucination detection is critical for financial RAG applications where incorrect answers about earnings, regulations, or investment data can have serious consequences. Its framework-agnostic design works with LangChain, LlamaIndex, and any other financial RAG stack without vendor lock-in. For finance teams, Phoenix provides free, self-hosted observability that ensures financial document retrieval quality without ongoing licensing costs — particularly valuable for budget-conscious fintech teams.
