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.
What viral AI launches share is the guide for it: model launches are the largest category in the directory and travel on the demo. Every launch we track in Frontier Lab is on that vertical's directory page.
