How to disable langsmith tracing for a specific llm call site without disabling other concurrent calls?

[p-barman]

Currently usingos.environ['LANGCHAIN_TRACING_V2'] = 'false' to disable logging for an llm call.
However, I noticed that doing so also disables logging for the time framer - of the other concurrent llm calls happening in FastAPI server.

Any suggestions?

Mostly like this:

with tracing_context(enabled=False)
   ...

I can double check whether this is takes precedence if it's mid-trace but that seems to not be relevant here.

We have a few docs on this, one being:
https://docs.smith.langchain.com/observability/how_to_guides/tracing/trace_without_env_vars

Ya toggling global environment in a process is bad practice and we cache it anyway so it wouldn't work.

Appreciate the suggestion but did not resolve my issue:

wrapping the callsite with tracing_context(enabled=False): still logged my run to langsmith!

Open to any more suggestions/debugging tips!

If it's mid-langchain trace we don't support that
