The models
It was built with six generations of Claude Opus, from Opus 4.5 in January 2026 to Opus 5.5 in October, together with Sonnet, Haiku and Fable models.
Honestly
A person still decides what matters. One founder sets the direction and reviews the work almost every day; Zefana does the engineering.
