+## Disabling LLM Observability conversion
+
+If you'd only like your generative AI spans to remain in APM and not appear in LLM Observability, you can disable the automatic conversion by setting the `dd_llmobs_enabled` attribute to `false`. Setting this attribute on any span in a trace prevents the entire trace from being converted to LLM Observability.
+
+### Using environment variables
+
+Add the `dd_llmobs_enabled=false` attribute to your `OTEL_RESOURCE_ATTRIBUTES` environment variable:
+
+```
+OTEL_RESOURCE_ATTRIBUTES=dd_llmobs_enabled=false
+```
+
+### Using code
+
+You can also set the attribute programmatically on any span in your trace:
+
+```python
+from opentelemetry import trace
+
+tracer = trace.get_tracer(__name__)
+
+with tracer.start_as_current_span("my-span") as span:
+    # Disable LLM Observability conversion for this entire trace
+    span.set_attribute("dd_llmobs_enabled", False)
+```

+OpenTelemetry traces that have [generative AI attributes](https://opentelemetry.io/docs/specs/semconv/gen-ai/gen-ai-spans/) are automatically converted into LLM Observability traces. To disable this conversion, see [Disabling LLM Observability conversion][38].
