Build AI agents that ship to production. User-scoped execution, rich UI components, and quota management built-in.
TruLens for LLMs
TruLens instruments your AI agent with OpenTelemetry, scores every step with benchmarked LLM judges, and tells you which version to ship.
About TruLens for LLMs
TruLens for LLMs provides tracing and evaluation for AI agents, including RAG workflows, MCP apps and summarization. It uses OpenTelemetry instrumentation and records per-step latency, inputs, outputs, tokens and cost, then applies LLM judges that explain their scores.
It can track multi-turn conversations, allow judges to be adjusted with rubrics, examples and score ranges, and compare app versions by average metric values to review quality and cost differences. Instrumentation is described for plain Python, LangGraph and LlamaIndex.
Key features
- Trace agent steps with latency, inputs, outputs, tokens and cost
- Score each step with LLM judges that include explanations
- Track and evaluate complete multi-turn conversations
- Customize judges with rubrics, examples and score ranges
- Compare app versions by average metric values in leaderboard
- Auto-instrument LangGraph and LlamaIndex or instrument plain Python
Best for: Developers building and iterating on agents, RAG systems, MCP apps and summarization workflows who need step-level traces and scores.
Good for
- Records per-step latency, inputs, outputs, tokens and cost
- Judge scores include explanations that point to the cause
