How Decart launched Lucy 2.5 on X

What this launch shows

From an account with 27K followers, this reached 176.9 times the account's own following. Accounts in the same band, 25K to 100K followers, reach a median of 20.9 times their following, so this travelled about 8.4 times further than usual for its size.

It ranks 33 of 264 launches from accounts that size. Against every launch in the directory it sits at 7 times the median of 688K views.

Every response ran below the directory's usual rate: 3K bookmarks, 410 replies, 365 quotes and 382 reposts against 4K likes.

The post was seen more than it was acted on, which is common for a launch that reaches past the people who care about the category. One bookmark for every 1 likes is a high ratio and usually means a product people intend to try.

The first line is “Meet Lucy 2.5, our most advanced Live AI model yet”. It carries a 39-second video against a directory median of 65 seconds.

Videos between 30 and 90 seconds have a median of 603K views in the directory. The copy runs 35 words, about the usual length for a launch post here, where the median is 41.

There is a link in the body, which costs a post some reach and buys it a place to send people. It went out on a Thursday. Launches posted on a Thursday have a median of 724K views in the directory, and Friday is the strongest day at 880K.

What viral AI launches share covers this: model launches are the largest category in the directory and travel on the demo. For the next one, read virality without conversion: reach that outruns response is the pattern this guide is about.

X analytics explained is the guide for it: what each of these numbers means, with benchmarks by account size. Every launch we track in Frontier Lab is on that vertical's directory page.
