 1. [`add_trace_processor()`][agents.tracing.add_trace_processor] lets you add an **additional** trace processor that will receive traces and spans as they are ready. This lets you do your own processing in addition to sending traces to OpenAI's backend.
 2. [`set_trace_processors()`][agents.tracing.set_trace_processors] lets you **replace** the default processors with your own trace processors. This means traces will not be sent to the OpenAI backend unless you include a `TracingProcessor` that does so.

+## Tracing with Non-OpenAI LLMs
+
+You can use an OpenAI API key with non-OpenAI LLMs to enable free tracing on the Openai Traces dashboard without disabling tracing.
+
+```python
+from agents import set_tracing_export_api_key, Agent, Runner, AsyncOpenAI, OpenAIChatCompletionsModel
+from dotenv import load_dotenv
+load_dotenv()
+import os
+
+set_tracing_export_api_key(os.getenv("OPENAI_API_KEY"))
+gemini_api_key = os.getenv("GEMINI_API_KEY")
+
+external_client = AsyncOpenAI(
+    api_key=gemini_api_key,
+    base_url="https://generativelanguage.googleapis.com/v1beta"

+- Set OPENAI_API_KEY in a .env file.
