Chat without relying on the cloud, shape Lumi’s personality to fit you, and enjoy conversations that stay on your device. With Lumi, you can: Chat with a personalized AI companion Use Lumi offline when Wi-Fi or service is unavailable Keep your conversations private and on-device Choose a personality or create your own custom one Talk with Lumi in a dedicated voice mode Share photos and documents for Lumi to understand Lumi now runs on Gemma 4, making it much more capable, more natural to talk to, and more useful for everyday conversation. Because Lumi runs locally, it needs serious power under the hood. Lumi is a large download and requires a device with 6GB or more of RAM. Supported devices include: iPhone 12 Pro or later iPhone 14 or later iPhone 17 or later unlocks the more powerful Ascended Lumi iPad and Apple Vision Pro are supported too This major update for Lumi makes a big step toward making it feel truly useful every day. More improvements are on the way as Lumi becomes more agentic, and I’d love to hear how it works for you. ~ Matt
