ABOUT

LangSmith is an all-in-one developer platform designed to streamline the development, debugging, testing, and monitoring of Large Language Model (LLM)-powered applications. Developed by LangChain, LangSmith offers tools for observability, evaluation, and prompt engineering, enabling developers to build production-grade LLM applications with confidence.

USE CASES

Application Debugging: Gain full visibility into the sequence of calls within your application to identify errors and performance bottlenecks in real-time.

Collaborative Development: Share chain traces with colleagues or clients to enhance explainability and facilitate collaboration between developers and subject matter experts.

Performance Evaluation: Construct datasets from production data, apply human feedback or AI-assisted evaluations, and conduct regression testing to ensure application quality over time.

Production Monitoring: Monitor cost, latency, and qualitative characteristics of live applications to promptly identify and address issues.

CORE FEATURES

Observability: Provides detailed traces of application workflows, allowing developers to debug and experiment with precision.

Collaboration Tools: Includes features like trace sharing, LangSmith Hub for prompt crafting and versioning, annotation queues for human labeling, and dataset management for evaluations and fine-tuning.

Evaluation Framework: Offers tools for constructing datasets, auto-evaluation using LLMs, regression testing, and online evaluation to continuously assess application performance.

Monitoring Dashboard: Enables tracking of user feedback, advanced filtering, cost analysis, error inspection, and latency monitoring to maintain application health.
