Think LLMs are too big to run on-device? Think again 📲
In this hands-on session, Callstack engineers show how they made *local* large language model execution possible in React Native—without relying on the cloud.
You’ll learn how the team combined the MLC LLM Engine with a new React Native package—`react-native-ai`—to run real-time text generation *on your phone*. From model switching with Vercel’s AI SDK to powering offline-first apps, this is what edge AI looks like in practice.
What you'll see
🛠️ Running LLMs locally on iOS and Android using `react-native-ai`
🛠️ How MLC enables high-performance, on-device inference
🛠️ Model switching in action with Vercel’s AI SDK
🛠️ Implementation trade-offs, developer gotchas, and upcoming improvements
🛠️ Why this matters for performance, privacy, and offline resilience
