Exploring Next — Ep 447 w/ Justy & Cody — Introducing Apex: A Fast, Specialized Model for React Native
Cody and Justy dig into Callstack's Apex, a specialized React Native coding model built on Gemma 4. Cody pushes on the self-reported benchmarks, the 'private beta with our own engineers' problem, and whether 'specialized' is real or just branding. Justy defends the economic logic—GitHub Copilot's billing shift proves general models are expensive—and argues that React Native's genuine cross-platform constraints make it a real candidate for specialization. They find middle ground on where Apex might actually earn its place versus where the claims outpace the evidence.
