 You can programmatically enable automatic tracing of LLM calls to a supported LLM model like OpenAI or a framework like LangChain by setting `integrations_enabled` to `true` in the `LLMOBs.enable()` function. In addition to capturing latency and errors, the integrations capture the input parameters, input and output messages, and token usage (when available) of each traced call.

+
+The OpenAI Agents integration converts the [built-in tracing][33] from the [OpenAI Agents SDK][34] into
+LLM Observability format and sends it to Datadog's LLM Observability product by adding a Datadog trace processor.

+The following operations are supported:
+- [`traces`][35]
+- [`agent`][36]
+- [`generation`][37] using Datadog's [OpenAI](#openai) integration
