Ori-Mnemos vs grafbase
Ori-Mnemos: Ori Mnemos is an open-source persistent memory infrastructure for AI agents that implements human cognition models on a knowledge graph. It uses ACT-R decay, spreading activation, and Hebbian learning to manage memory, and achieves state-of-the-art retrieval performance while being zero-infrastructure and portable.; grafbase: Grafbase is a self-hosted, Rust-powered GraphQL Federation Gateway for high-scale, mission-critical applications. It unifies diverse data sources and microservices into a single, performant GraphQL API, offering enterprise-grade security and flexible deployment options.
01
TL;DR
Choose Ori-Mnemos if…Multi-hop retrieval QA (e.g., HotpotQA)
Choose grafbase if…Unifying disparate microservices, legacy systems, and third-party APIs into a single federated GraphQL API.
