The first line is “Introducing AssemblyAI-TTS-1, our first text-to-speech model”, the same first word as 25% of launches in the directory. It carries a 1:30 video against a directory median of 66 seconds. Videos between 30 and 90 seconds have a median of 537K views in the directory.

The copy runs 37 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 622K views in the directory, and Friday is the strongest day at 647K.

Developer marketing strategy covers this: developers try before they read, so the post has to let them. For the next one, read X analytics explained: what each of these numbers means, with benchmarks by account size. Every launch we track in Developer Tool is on that vertical's directory page.
