R2R: The Most Advanced AI Retrieval System (V3 API Release)

Hey HN,

We've just released R2R V3 with a completely RESTful API that covers everything you need for production RAG applications. The biggest change is our Git-like knowledge graph architecture, but we've also unified all the core objects you need to build real applications.

Check our [API](https://r2r-docs.sciphi.ai/api-and-sdks/introduction) or join our [Discord](https://discord.gg/p6KqD2kjtB) if you want to dive deeper. We'd love feedback from folks building in production!
