Local, on-device LLMs unlock private-by-default, low-latency AI experiences that work offline, which is ideal for mobile. In this talk, Szymon will show how to run LLMs directly inside React Native apps using an AI SDK that provides a powerful abstraction layer to simplify building AI applications. Join him as he explores `react-native-ai`, a library that enables local LLM execution. He'll dive into the provider architecture, integrations with MLC LLM Engine and Apple's foundation models, and what's new: improved debugging experiences, tool calling support, and agent pipelines for building AI workflows that run entirely on-device.
