Introducing Mem0

Mem0's September 2024 launch post from founder Taranjeet Singh. The product thesis is hybrid storage — vector for semantic similarity, graph for relationships between entities, key-value for fast fact retrieval — wrapped in an extract-store-retrieve pipeline that runs automatically on chat history instead of making developers write memory logic by hand. Later benchmark claims against OpenAI's built-in memory: 26% higher accuracy, 91% lower latency, 90% token savings. Numbers aside, Mem0 is worth reading because it's the cleanest articulation of the hybrid school's position: you don't pick one index, you compose three, and the integration layer is the product.
