Would you pay $20 a month for access to AI hardware you already own? That appears to be one of Meta’s next bets. This week, it quietly announced that your glasses’ Conversation Focus feature will soon be limited to three hours of use per month, unless you pay for a $19.99 Meta One Premium subscription.

In a help article, the company insists that it won’t require a subscription to use your glasses, period; it’s merely erecting a “rate limit” for certain AI features. Even premium subscribers will only get 15 hours of Conversation Focus per month under that “rate limit,” it claims.

Problem is, Meta’s rate limit is ridiculous. The Conversation Focus feature, which amplifies the voice of the person you’re speaking to so you can hear better in noisy environments, is not something that should plausibly be rate-limited, because it doesn’t use Meta’s servers. It runs on-device, using the chips inside the glasses that you’ve already purchased. I turned off my internet, and it kept working.

Here’s how the company introduced it last year: “[C]onversation focus uses your AI glasses’ open-ear speakers, beamforming technology, and real-time spatial processing to dynamically amplify the voice of the person you’re talking to.”

Not only does it avoid Meta’s servers, but Conversation Focus doesn’t technically require an internet connection at all. I double-checked by turning off my phone’s Wi-Fi and cellular, turning on Airplane Mode, and I was still able to use Conversation Focus just fine by tapping a button on my phone.

Does Meta have some secret licensing deal with another company that costs it money every time a person uses Conversation Focus? Failing that, the rate limit sounds utterly bogus.

We’ve asked if Meta can explain the move, and whether the company plans to put other on-device features behind a subscription. Meta didn’t immediately respond to a request for comment.
