Brilliant Labs Halo: The Only Fully Open-Source AI Smart Glasses — $349, 40g, All Processing On-Device

Every big tech company is shipping AI glasses right now. Meta, Google, Snap — all closed ecosystems where your camera feed goes straight to their cloud. Brilliant Labs took the opposite bet. Halo is fully open-source AI smart glasses — hardware design files, firmware, SDK, everything on GitHub — and with the new Alif Semiconductor partnership announced in March 2026, all AI inference runs locally on the Balletto B1 chip. Nothing leaves the device.

The Hardware

40g. Color micro-OLED display adjustable from +2 to -6 diopters. Dual bone conduction speakers, dual mics, IMU for gesture control, and a low-power optical sensor for visual AI. The Balletto B1 packs an Arm Cortex-M55 CPU plus Ethos-U55 NPU — enough to run real-time translation, conversational AI, and sensor fusion without cloud roundtrips. Battery lasts up to 14 hours. Noa, the built-in AI assistant, holds long-term memory of what you’ve seen and heard.

Why Developers Care: Fully Open SDK

This is what separates Halo from everything else. The entire stack is hackable. Brilliant SDK (Flutter, iOS/Android), ZephyrOS firmware with Lua API, and 20+ repos on GitHub under brilliantlabsAR. You can build custom agents, swap out Noa entirely, modify gesture responses, or write new Vibe Mode mini-apps — natural language prompts that generate on-demand AI workflows right on the glasses. If you’re building autonomous hardware agents or experimenting with on-device robotics, Halo is the most accessible wearable dev platform available today.
