…onse IDs Addresses 4 critical OpenTelemetry span issues in LiteLLM: Issue #3: Remove redundant attributes from raw_gen_ai_request spans - Removed self.set_attributes() call that was duplicating all parent span attributes (gen_ai.*, metadata.*) onto the raw span - Raw span now only contains provider-specific llm.{provider}.* attributes - Reduces storage and eliminates search confusion from duplicate data Issue #4: Prevent attribute duplication on litellm_proxy_request parent span - When litellm_request child span exists, removed redundant set_attributes() call on the parent proxy span - Child span already carries all attributes; parent duplication doubles storage and complicates search Issue #5: Fix orphaned guardrail traces - Guardrail spans were created with context=None when no parent proxy span existed, resulting in orphaned root spans (separate trace_id) - Added _resolve_guardrail_context() helper to ensure guardrails always have a valid parent (litellm_request or proxy span) - Applied fix to both _handle_success and _handle_failure paths Issue #8: Add gen_ai.response.id for embeddings and image generation - EmbeddingResponse and ImageResponse types don't have provider response IDs - Added fallback to standard_logging_payload["id"] (litellm call ID) for correlation across LiteLLM UI, Phoenix traces, and provider logs - Completions still use provider ID (e.g. "chatcmpl-xxx") when available Tests added: - TestRawSpanAttributeIsolation: Verify raw span has no gen_ai/metadata attrs - TestNoParentSpanDuplication: Verify parent span doesn't get duplicated attrs - TestGuardrailSpanParenting: Verify guardrails are children (not orphaned) - TestResponseIdFallback: Verify response ID set for all call types All existing OTEL tests pass (73 passed, 14 pre-existing protocol failures).
