About Phoenix
Phoenix is an open-source AI observability platform designed to help developers, MLOps engineers, and data scientists understand, evaluate, and improve their Large Language Model (LLM) applications. It provides comprehensive tools for visualizing LLM application traces, allowing users to inspect prompts, responses, and all intermediate steps within complex LLM chains. A core capability is its robust evaluation framework, which includes built-in metrics for assessing aspects like toxicity, sentiment, and hallucination, alongside support for custom evaluators to meet specific project needs. Phoenix also offers powerful monitoring features for production LLM applications, enabling teams to track performance, cost, and quality over time. Furthermore, it facilitates experimentation, allowing users to compare different LLM models, prompt engineering strategies, and configuration settings to optimize application behavior. The platform supports seamless integration with popular LLM frameworks and providers such as LangChain, LlamaIndex, OpenAI, Anthropic, and Hugging Face. Its open-source nature provides flexibility for self-hosting, while a managed cloud option is also available. Phoenix is crucial for debugging LLM applications, refining prompt engineering, ensuring model reliability, and driving continuous improvement in AI-powered products.
