The Model Is Not the Product: A Dual-Pillar Architecture for Local-First Psychological Coaching
Researchers have developed Psych LM, an iOS application designed for psychological coaching that prioritizes its architecture over the language model itself. This local-first application utilizes an on-device model and a novel memory corpus system to maintain persistent context, effectively simulating a near-infinite context window. The system's design emphasizes privacy, a structured memory component, a deterministic orchestration layer, and a benchmark framework for evaluating reliability under mobile constraints. AI
IMPACT Demonstrates how architectural innovation can enable sophisticated AI applications on mobile devices, prioritizing privacy and context.
