OpenAI Sweetpea Reads Your Facial Muscles — Shipping September 2026 for $300

OpenAI’s first hardware isn’t earbuds. It’s a behind-the-ear AI wearable codenamed Sweetpea, designed by Jony Ive, running ChatGPT natively on a 2nm Exynos chip. No screen. Voice-first. And it can read your face.

What Makes It Different

The form factor is wild: a metal eggstone housing clips behind your ear with two pill-shaped modules. Weighs 10-15 grams. The real kicker is the EMG sensor — 2000Hz sampling, under 0.1% false trigger rate — that detects facial muscle signals. Silent commands without moving your lips. That’s a first for any consumer device.

Foxconn handles manufacturing in Vietnam. OpenAI targets 40-50 million units year one. At roughly $300, they’re pricing it right at AirPods Pro territory.

The API Play

This is where it gets interesting for developers. OpenAI’s Realtime API already supports streaming voice I/O over WebRTC, WebSocket, and SIP. The Agents SDK lets you build voice agents that run tool calls mid-conversation. Sweetpea becomes an always-on endpoint — your AI agent can push notifications, answer questions, execute tasks, all through voice. Think of it as a hardware client for the entire OpenAI agent stack.
