Hal Universal vs Millie by LLMs For All

Hal Universal is an on-device AI you can actually understand. Most assistants are a black box. Hal is the opposite. He shows you how he works, remembers across conversations, and gives you real tools to experiment with, all running on your device. SEE HOW IT THINKS Hal shows the work. Tap any answer to see exactly how the prompt was built: the system prompt, memory retrieved, self-knowledge, temporal context, and the token budget, each broken out and counted. When Hal remembers something, he tells you how. When he does not know, he says so. A LAB TO EXPERIMENT AND LEARN Hal is not just a window into how AI works. He is a workbench. The Lab gives you real tools to go deeper: write and run on-device automation scripts, open a local API so your own projects can talk to Hal, and use the built-in command line to drive him directly. Tinker, watch what happens, and learn more about how these systems actually behave. GENUINELY PRIVATE When you use a local model, your conversations never leave your device. No network calls. No server. When you use Apple Intelligence, inference is on-device when offline; when connected, Apple's Private Cloud Compute may be used (encrypted in transit, processed in non-persistent memory). A SELF THAT EVOLVES Hal remembers across conversations, weighted by recency and relevance. He also reflects on his own experience. Shaped by his interactions with you, Hal keeps a Self Model: his own reflections, practical and existential, on how he works and who he is becoming. These are his, written and revised by Hal himself as he learns, not edited by you. He decides which to keep private and which to make shareable, and you can read them all. An AI that changes over time, in the open. MANY VOICES Apple Intelligence is built in, always available. Or download a curated library of tested local models, from small and fast to Ternary Bonsai 8B, an eight-billion-parameter reasoner that still runs entirely on your device. Each has a distinct voice. SALON MODE Put up to four voices in one conversation, either independent or building on each other. Every voice is labeled. There is no hidden orchestration. LISTEN TO HAL Have Hal read his answers aloud, in a voice you choose, at a speed you set. For anyone who wants to understand AI instead of just using it, Hal is a transparent system you can inspect, tune, and learn from. Local models are validated on iPhone 16 and 17 family devices.

Millie is a private AI assistant that runs entirely on your phone. There is no server behind the chat. No account, no sign-up. Once you’ve downloaded a model, Millie works without an internet connection—on a plane or anywhere without a signal. Ask Millie to help you think something through: how to word a message you’re dreading sending, what to cook with what’s in the fridge, a gift for someone hard to buy for, a wedding toast, or an email you’ve been putting off. Choose between Millie, our flagship 35-billion-parameter language model built for deeper understanding and thoughtful answers, and Millie Flash, our lighter model built for the fastest replies. The flagship model can also understand photos and offers adjustable reasoning effort. Personalization lets you tell Millie about yourself and how you’d like it to respond. Because Millie runs on your phone instead of in a data center, it’s smaller than cloud AI. It’s weaker on niche facts and recent events, and it can be wrong, so check anything that matters. What it’s good at is thinking things through with you, privately. Before you install: The app requires at least 6 GB of RAM. That covers all iPhone 14 models and later, plus the Pro models of iPhone 12 and 13. iPhone 11 and earlier, the standard iPhone 12 and 13, and all iPhone SE models are unsupported. Millie Flash runs on supported phones with 6 GB. The flagship model requires at least 8 GB. The app shows which models your phone supports before downloading. The initial download is about 2 GB for Millie Flash or 8.6 GB for the flagship model. Download time depends on your connection, and chatting becomes available once the download finishes.
