Installation
Usage
The LangWatch API key is configured by default via the
LANGWATCH_API_KEY environment variable.autotrack_openai_calls() to automatically capture all OpenAI calls made with a specific client instance within a trace.
@langwatch.trace() decorator creates a parent trace, and autotrack_openai_calls() enables automatic tracking of all calls made with the specified client instance for the duration of that trace.
Check it worked
Run the example. Then open your project in LangWatch: a new trace named “OpenAI Chat Completion” appears in the traces list within a few seconds. Open it to see the OpenAI chat completion nested inside it, with its input and output. If no trace appears, check thatLANGWATCH_API_KEY is set in the environment the script runs in.
