OpenTelemetry GenAI Utils

The GenAI Utils package will include boilerplate and helpers to standardize instrumentation for Generative AI. This package will provide APIs and decorators to minimize the work needed to instrument genai libraries, while providing standardization for generating both types of otel, “spans and metrics” and “spans, metrics and events”

This package relies on environment variables to configure capturing of message content. By default, message content will not be captured. Set the environment variable OTEL_SEMCONV_STABILITY_OPT_IN to gen_ai_latest_experimental to enable experimental features. Set the environment variable OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT to one of: - NO_CONTENT: Do not capture message content (default). - SPAN_ONLY: Capture message content in spans only. - EVENT_ONLY: Capture message content in events only. - SPAN_AND_EVENT: Capture message content in both spans and events.

To control event emission, you can optionally set OTEL_INSTRUMENTATION_GENAI_EMIT_EVENT to true or false (case-insensitive). This variable controls whether to emit gen_ai.client.inference.operation.details events. If not explicitly set, the default value is automatically determined by OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT: - When NO_CONTENT or SPAN_ONLY is set: defaults to false - When EVENT_ONLY or SPAN_AND_EVENT is set: defaults to true If explicitly set, the user’s value takes precedence over the default.

This package provides these span attributes:

• gen_ai.provider.name: Str(openai)

• gen_ai.operation.name: Str(chat)

• gen_ai.request.model: Str(gpt-3.5-turbo)

• gen_ai.response.finish_reasons: Slice([“stop”])

• gen_ai.response.model: Str(gpt-3.5-turbo-0125)

• gen_ai.response.id: Str(chatcmpl-Bz8yrvPnydD9pObv625n2CGBPHS13)

• gen_ai.usage.input_tokens: Int(24)

• gen_ai.usage.output_tokens: Int(7)

• gen_ai.input.messages: Str(‘[{“role”: “Human”, “parts”: [{“content”: “hello world”, “type”: “text”}]}]’)

• gen_ai.output.messages: Str(‘[{“role”: “AI”, “parts”: [{“content”: “hello back”, “type”: “text”}], “finish_reason”: “stop”}]’)

• gen_ai.system_instructions: Str(‘[{“content”: “You are a helpful assistant.”, “type”: “text”}]’) (when system instruction is provided)

When EVENT_ONLY or SPAN_AND_EVENT mode is enabled and a LoggerProvider is configured, the package also emits gen_ai.client.inference.operation.details events with structured message content (as dictionaries instead of JSON strings). Note that when using EVENT_ONLY or SPAN_AND_EVENT, the OTEL_INSTRUMENTATION_GENAI_EMIT_EVENT environment variable defaults to true, so events will be emitted automatically unless explicitly set to false.
