respan-instrumentation-google-genai

Respan instrumentation plugin for the official Google Gen AI SDK.

The package patches google.genai.models.Models and AsyncModels generation methods and emits canonical Respan chat spans through the active OTEL pipeline. It captures sync calls, async calls, streaming calls, prompt and completion content, token usage, tool definitions, and model function calls.
