Toggle tracing on and off

note

This section is only relevant for users who are

• Using @traceable/traceable
• Wrapping the OpenAI client
• Using the trace environment variable
• Using LangChain

If you've decided you no longer want to trace your runs, you can unset the LANGCHAIN_TRACING_V2 environment variable. Traces will no longer be logged to LangSmith. Note that this currently does not affect the RunTree objects or API users, as these are meant to be low-level and not affected by the tracing toggle.
