BrainAPI beats Mem0/Zep; bottleneck is infra, not models

shbong · reddit · 2026-08-30

The author released BrainAPI, claiming top scores on LoCoMo and BEAM1M benchmarks against Mem0, Zep, and Letta. However, the key insight is the shift in development velocity: using Cursor, arXiv MCP, and planning mode reduced research-to-implementation time from months to weeks. The author argues that agent failures in production are often infrastructure problems (retrieval, context structure, workflows), not model intelligence. BrainAPI uses an event-centric graph to enable multi-hop reasoning.
