LLM Inference on Edge: A Fun and Easy Guide to run LLMs via React Native on your Phone!

Honestly, running LLMs on-device via React Native is mostly a performance illusion right now. We're hitting massive memory constraints on mid-sized models; you can't just shove a 7B parameter model into a phone easily without heavy quantization, which kills quality. It's cool for demos, but production deployment is still a headache. You're trading speed for accuracy, and most of the real work is squeezing the model down to run efficiently without blowing up the battery.
