What this launch shows

Runway posted this from an account with 293K followers and reached about 40.4% of them. The median for over 100K followers is 2.4 times, so this one stayed closer to home than most.

It ranks 560 of 611 launches from accounts that size. Against every launch in the directory it is below the median of 688K views, at rank 1539 of 1981.

Quote posts led, 42 of them at 3.5 per 10,000 views against a median of 1.3.

People were adding their own take, which is how a launch gets argued about and carried into audiences the account does not have. Bookmarks: 234. Reposts: 55.

The first line is “Introducing Praxis-1, an open-weight World Action Model that turns our video pre-training expertise into real world control for…”, the same first word as 25% of launches in the directory.

It carries a 1:55 video against a directory median of 65 seconds. Videos over 90 seconds have a median of 651K views in the directory.

The copy runs 43 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 Wednesday. Launches posted on a Wednesday have a median of 721K views in the directory, and Friday is the strongest day at 880K.

Attributing signups to a launch covers this: a save rate this high is the number to follow into the product. For the next one, read giving people something to reply to: the conversation is what carried this one.

Why posts from large accounts under-reach is the guide for it: a post seen by fewer people than follow the account was held back by the ranking model. This launch sits in the Robotics and Frontier Lab directories.
