A newer LLM application framework just dropped, and of course I had to try it out. The reason I know about this is through the LinkedIn AI community, there was a lady who was giving HEAVY critique of the current libraries, Langchain/LlamaIndex/Haystack/etc...
This is an alpha release and I was actually pleasantly surprised. I would describe it as a middle ground between Instructor and DSPy. It gives you nice base classes and a nice way to compose what you create with those classes.
