Viewing LLM Model Temperature in UI Trace/Span

Yes, Phoenix traces capture LLM parameters such as temperature, and you can inspect these parameters—including temperature—in the trace details within the UI. This allows you to validate and debug the configuration used for each LLM call, as described in the documentation and shown in trace attribute examples (source, source, source).To view the temperature, open a trace in the Phoenix UI, select the relevant LLM span, and look for the llm.invocation_parameters or similar attribute, which will include the temperature value used for that call.
