# The Offline AI: On-Device LLMs in React Native With AI SDK

Learn how to run on-device LLMs in React Native using Vercel’s AI SDK from Michał Pierzchała's talk at DevAI by Data Science Summit.

_Talk · 12/5/2025 · Warsaw, Poland · Category: AI_

Organizer: DevAI

Speakers: Michał Pierzchala (Principal Engineer @ Callstack)

On-device LLMs, unlike remotely accessed models, unlock private-by-default, low-latency AI experiences that work anywhere, offline; ideal for mobile. In this talk, Michał will show how to run LLMs directly inside React Native apps using Vercel's AI SDK that provides a robust abstraction layer to simplify building AI applications. Same interface to run local and remote models. These capabilities are possible thanks to an open-source set of libraries we created. He'll dive deep into the provider architecture and demonstrate how we integrated it with the MLC LLM Engine and Apple’s Foundation Models available on their latest mobile devices.
