What this launch shows
The post went out from an account with 20K followers and was seen by fewer people than follow the account. For 5K to 25K followers the usual multiple is 50.8, so the ranking model showed this to fewer strangers than it shows most launches.
It ranks 472 of 479 launches from accounts that size. Against every launch in the directory it is below the median of 688K views, at rank 1955 of 1981.
Likes led, 65 at 168 per 10,000 views against a median of 26.8, with the heavier signals closer to usual: 9 bookmarks, 5 replies, 0 quotes. A like is a reaction. The post was enjoyed more than it was kept.
It starts “GLM-5.3 is now live with vision, only on Baseten Model APIs”. It carries a 40-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 29 words, about the usual length for a launch post here, where the median is 41.
The body carries a link, so the post had somewhere to send the reader and paid a little reach for it. It went out on a Friday. Launches posted on a Friday have a median of 880K views in the directory, which makes it the strongest day.
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.
Developer marketing strategy is the guide for it: developers try before they read, so the post has to let them. Every launch we track in Developer Tool is on that vertical's directory page.
