KEY INSIGHT
Scale for local AI products means different things than cloud scale. You're not scaling API calls—you're scaling the diversity of hardware configurations your product runs on, the efficiency of model distribution, and the reliability of offline-first architecture.
True scale planning for local AI: model compression techniques that expand your reachable market, efficient update mechanisms that work on limited bandwidth, and fallback strategies when constraints are extreme.

Scale planning reveals product architecture decisions. If your model sizes require 30GB downloads, you've segmented out mobile professionals. Compression investments directly expand market reach.
