When enabled, OpenTelemetry spans are emitted for agent CRUD, response generation (chat/invoke_agent), and streaming operations with GenAI semantic convention attributes, token usage metrics, and optional content recording gated by the `OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT` environment variable. - Added protocol-style methods on `ResponsesClient` and `ResponsesAsyncClient` that accept a raw JSON request body (`BinaryData`) and a `com.openai.core.RequestOptions`, and return the openai-java raw HTTP response. These mirror the existing `createAzureResponse` and `createStreamingAzureResponse` typed surface: `createResponseWithResponse` (returns `HttpResponseFor`) and `createResponseStreamWithResponse` (returns `HttpResponseFor>`). They delegate to the underlying openai-java `ResponseService.withRawResponse()` surface and continue to flow through the Azure HTTP pipeline. ### Other Changes diff --git a/sdk/ai/azure-ai-agents/README.md b/sdk/ai/azure-ai-agents/README.md index a52231658900..c5211c5dbd22 100644 --- a/sdk/ai/azure-ai-agents/README.md +++ b/sdk/ai/azure-ai-agents/README.md @@ -740,6 +740,46 @@ If there are significant differences, API calls may fail due to incompatibility.
