What this launch shows
The post went out from an account with 157K followers and was seen by fewer people than follow the account. For over 100K followers the usual multiple is 2.2, so the ranking model showed this to fewer strangers than it shows most launches.
It ranks 675 of 678 launches from accounts that size. Against every launch in the directory it is below the median of 603K views, at rank 2230 of 2314.
Replies led. 5 of them, 5.7 per 10,000 views against a median of 2.5.
The post started a conversation, and the ranking model pays for conversation with reach in the hours after. Bookmarks came in at 11, reposts at 5.
It starts “AssemblyAI-TTS-1 is now live on OpenRouter”. It carries no media, which leaves the ranking model nothing to hold a reader with past the first line. The copy runs 40 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 Wednesday. Launches posted on a Wednesday have a median of 622K views in the directory, and Friday is the strongest day at 647K.
Giving people something to reply to covers this: the conversation is what carried this one. For the next one, read why posts from large accounts under-reach: a post seen by fewer people than follow the account was held back by the ranking model.
Whether a launch needs a video is the guide for it: 99% of the launches in the directory carry one, and the guide is about when the 1% is the right call. Every launch we track in Developer Tool is on that vertical's directory page.
