PSA: Check your Langfuse traces. Their SDK intercepts other tools' traces by default and charges you for them.

If you use Langfuse alongside evaluation tools like DeepEval or local runners, check your usage dashboard. You might be paying for thousands of traces you never meant to send them. What's happening: Instead of only tracking what you explicitly tell it to, their SDK attaches to the global TracerProvider. By default, it greedily intercepts and uploads any span in your application that has gen_ai.* attributes or known LLM scopes - even from completely unrelated tools running in the same process.
