GenAI Engineer Session 13 Tracing, Monitoring and Evaluation with LangSmith and LangWatch
Buraq ai
With AI agents powering more systems in 2025, selecting the right evaluation and observability platform is a strategic choice. This video walks through four leading platforms and helps you understand how they compare across feature sets, deployment styles, and use cases: Maxim AI (https://getmax.im/Max1m) – Built for end-to-end workflows: simulation, evaluation, prompt versioning and production monitoring. Its strengths lie in enterprise readiness, integrated architecture and advanced evaluation capabilities. Arize Phoenix – An open-source observability framework designed for tracing and evaluating LLM-based systems, particularly useful for development and experimentation phases. Langfuse – Also open source, with strong tracing, prompt management, usage metrics and self-hosting flexibility. A good fit when you value customization and full control. LangSmith – Designed for users working within the LangChain ecosystem. Supports prompt/debug workflows and trace logging, especially in LangChain-centric projects. Key comparisons include: Observability & tracing (distributed spans, tool-calls, alerts) Evaluation workflows (single turn vs multi-turn agents, human vs automated) Prompt management and version control Deployment modalities (SaaS, self-host, enterprise compliance) Pricing and total cost of ownership Why this matters: If your AI agent architecture is simple, a lightweight tool may suffice. But for complex, agentic systems with tool-calls, memory, branching workflows and production traffic, you’ll want a platform that supports evaluation, observability and iteration end-to-end.
