The AI Pendant Bust — What Happened to Humane, Rabbit, and the "AI Hardware" Wave

In 2024, three products defined a supposed new category — standalone AI hardware — that was going to replace parts of the smartphone. Two years on, the honest accounting is that the category mostly didn't survive contact with reality.

Humane AI Pin: the clearest failure

Launched April 2024 at $699. Now fully discontinued: HP acquired Humane's assets and patents, and — critically — the cloud service the Pin depended on for its AI functionality shut down February 28, 2025. A Humane Pin still owned in 2026 is inert hardware, because its intelligence lived on Humane's servers, not on the device.

Rabbit R1: alive, but in real distress

Sold around 100,000 units on CES-driven hype in early 2024, then faced substantial returns once the "Large Action Model" pitched at launch didn't work as demonstrated. Tom's Guide and TechSpot both report employees unpaid for months, with a group on strike since October, even as the company teases new hardware.

What actually found product-market fit

Pendant-style voice recorders like Limitless, which narrowed ambition drastically: they record and summarize conversations rather than acting as a general AI agent. Meta acquired Limitless outright on December 5, 2025 — and immediately stopped selling the Pendant to new customers.

The pattern

Products that overpromised general-purpose AI agency on unproven hardware either died or are dying; the product that promised something narrow got acquired by a company big enough to actually ship it. The AI PC (Microsoft's Copilot+ spec) remains the closest thing to a mature, well-specified AI hardware category for consumers today.
