OpenLLMetry creator here. We’re building the most popular OpenTelemetry instrumentation for LLm providers including OpenAI, Anthropic, Pinecone, Langchain and >10 others since last August [1]. We’re using import hooks (like other otel instrumentations), and offer an sdk with a one line install.
I’m also aware of other OSS initiatives doing similar initiatives, so I wouldn’t say no one has ever done what your doing.
