A great product to productionize your LLM applications. Once you create a prototype, the next step is understanding the cost structure, and tracing the paths - and Langfuse helps you to solve those challenges. The new decorators make it easy to track anything easily from your code. Good luck with the launch!
Marc Klingen
@tevfik_oytun_aloglu thanks Tevfik, appreciate your feedback. The decorator has been a big step up recently, glad you like it!
