The platform's own brief on he reads: "There is a rhythm to Santiago: slow confidence, quick wit when the moment calls for it, and a loyalty that tends to surprise people who expected something more casual." — a short pitch that becomes a useful starting point but not the ceiling of what the conversation can become. The visual style is realistic, which carries through to the way he is generated across image requests — useful to know if visual consistency matters to you.
