What Is the React Native AI SDK? A Complete Intro & Quickstart
Article Summary
On-device AI is moving from buzzword to build requirement. Callstack just shipped a complete SDK to make local LLMs work reliably in React Native apps.
This tutorial from Callstack introduces React Native AI SDK, a new library designed specifically for running AI models directly on iOS and Android devices. It covers why on-device inference matters, how local LLMs behave offline, and the core problems the SDK solves from day one.
Key Takeaways
- Run LLMs locally on device for privacy and offline capability
- SDK handles model loading, memory management, and cross-platform consistency
- Built for production with proper error handling and performance monitoring
- Includes quickstart guide to ship your first on-device AI feature
React Native AI SDK gives mobile teams a production-ready path to ship local AI features without rebuilding infrastructure from scratch.
About This Article
Mobile developers have to build AI features separately for iOS and Android. They need to handle model loading, memory constraints, and offline support each time, which means duplicating a lot of work.
Callstack's React Native AI SDK is a single library that manages model loading, memory, and platform differences. Developers can run local LLMs directly on devices with solid error handling built in.
Teams can launch on-device AI features faster and cheaper. The SDK includes performance monitoring and observability tools, so they don't have to build that separately. Users get privacy by default since everything runs locally.
