Fair point and you're right I should have said largest commonly deployed in consumer companion apps rather than largest period. Behemoth at 123B exists but none of the platforms I tested are actually running that in production. Sloppy phrasing on my part, appreciate the correction.
Memory is the most marketed and least delivered feature in the AI companion space. Most platforms claim to remember you but either reset between sessions or just pull from a profile you filled in manually. After two years of testing the ones that actually carry real conversational context across weeks are rare.

After testing about 40 platforms the pattern is always the same. Memory is the most marketed and least delivered feature. Most apps claim to remember you but reset completely between sessions or just store what you typed in your profile manually. The ones that actually carry conversational context across weeks are rare and the difference in experience is significant. An AI that references something you mentioned three weeks ago without prompting feels qualitatively different from one treating every session like a first meeting.

Right? A year ago 70B felt massive and now it's basically mid-tier. The pace of this is genuinely hard to keep up with even when you're paying close attention to it.
