{"library":"langsmith","type":"library","category":null,"description":"Official Python SDK for LangSmith — LangChain's observability, tracing, and evaluation platform. Instruments LLM calls, chains, agents, and arbitrary functions with the @traceable decorator or wrap_openai(). Traces are sent asynchronously to LangSmith cloud (or self-hosted). Also provides dataset management and evaluation (evaluate()) APIs. Usable standalone without LangChain. Releases multiple times per week. SECURITY NOTE: CVE-2026-25528 — SSRF via baggage header injection, fixed in 0.6.3. Any version 0.4.10–0.6.2 is vulnerable.","language":"python","status":"active","version":"0.7.7","tags":["langsmith","tracing","observability","langchain","evaluation","llm-monitoring","traceable","evals"],"last_verified":"Tue Jun 09","install":[{"cmd":"pip install langsmith","imports":["from langsmith import traceable","from langsmith.wrappers import wrap_openai","from langsmith import Client"]},{"cmd":"pip install 'langsmith[otel]'","imports":[]},{"cmd":"pip install 'langsmith[pytest]'","imports":[]}],"homepage":"https://smith.langchain.com/","github":"https://github.com/langchain-ai/langsmith-sdk","docs":"https://docs.smith.langchain.com/","changelog":null,"pypi":"https://pypi.org/project/langsmith/","npm":null,"openapi_spec":null,"status_page":null,"smithery":null,"compatibility":{"summary":{"python_range":"3.10–3.9","success_rate":100,"avg_install_s":7,"avg_import_s":1.44,"wheel_type":"wheel"},"url":"https://checklist.day/v1/registry/langsmith/compatibility"}}
