Best for: Developers building LLM applications

Visit GenSphere

GenSphere is a GitHub framework that takes a declarative approach to building LLM applications. Instead of writing lots of glue code, you describe how the parts of your application fit together and the framework handles the rest.

This can make AI projects easier to read, share and change. It is free and open source, aimed at developers who want a structured way to assemble language model workflows.
