Design facile da implementare: architettura progettata per essere pratica per applicazioni reali, non solo per dimostrazioni di ricerca.
Sviluppo congiunto della comunità: collaborazione attiva con la più ampia comunità di intelligenza artificiale per miglioramenti e applicazioni dei modelli.

Impatto nel mondo reale
I modelli aperti di Stability hanno permesso un'esplosione di creatività e sviluppo di applicazioni che sarebbe stata impossibile con regimi di licenza chiusi. Dalle piattaforme di generazione artistica agli strumenti di progettazione fino ai flussi di lavoro di produzione multimediale, questi modelli sono stati integrati in migliaia di applicazioni al servizio di milioni di utenti.
Per i creatori, i modelli forniscono nuovi strumenti per l'espressione visiva senza richiedere una formazione artistica. Per gli sviluppatori, offrono elementi costitutivi per la creazione di applicazioni specializzate senza i limiti e i costi delle API chiuse. Questo si è rivelato particolarmente prezioso per le piccole imprese e i singoli creatori che altrimenti non avrebbero potuto accedere a tale tecnologia.
Emad Mostaque, fondatore di Stability AI, sottolinea questa filosofia: "Crediamo nei modelli aperti perché consentono un'innovazione che non possiamo prevedere. Quando si blocca la tecnologia dietro le API, si limita ciò che le persone possono creare a ciò di cui si prevede che abbiano bisogno".
