This is an optional instrumentation of the OpenAI SDK which simplifies getting started, tracking token counts, model parameters and streaming latencies.

Langfuse is not in the critical path, this just helps with instrumentation.

You can use the Langfuse Python SDK / Decorator to track any LLM (with some instrumentation code) or use one of the framework integrations.

Here is a fully-featured example using the Amazon Bedrock SDK: https://langfuse.com/docs/integrations/amazon-bedrock

Nice work but, Sorry but I don’t feel comfortable either proxying my llm calls through a 3rd party unless the 3rd party is a llm gateway like litellm or arch or storing my prompts in a SaaS. For tracing, I use OTEL libraries which is more than sufficient for my use case.
