+Graphiti powers the core of [Zep's memory layer](https://www.getzep.com) for LLM-powered Assistants and Agents.
+
+Using Graphiti, we've demonstrated Zep is the [State of the Art in Agent Memory](https://blog.getzep.com/state-of-the-art-agent-memory/).

+Read our paper: [Zep: A Temporal Knowledge Graph Architecture for Agent Memory](https://arxiv.org/abs/2501.13956).

 Graphiti is under active development. We aim to maintain API stability while working on:
 
-- [x] Implementing node and edge CRUD operations
-- [ ] Improving performance and scalability
-- [ ] Achieving good performance with different LLM and embedding models
-- [x] Creating a dedicated embedder interface
 - [ ] Supporting custom graph schemas:
   - Allow developers to provide their own defined node and edge classes when ingesting episodes
   - Enable more flexible knowledge representation tailored to specific use cases
