À Propos de LiberaGPT

LiberaGPT est un assistant IA pour iPhone qui fonctionne entièrement sur l'appareil. Aucune connexion internet n'est requise pour aucune partie de ses fonctionnalités principales. Aucune donnée n'est transmise, stockée à distance ou partagée avec des tiers.

L'application est livrée avec un modèle performant préinstallé et permet aux utilisateurs de télécharger des modèles supplémentaires à la demande. Tout le traitement se fait sur le téléphone grâce au Neural Engine et au GPU des puces A18 et A19 Pro.

"Libera" est le latin pour libre. Le nom reflète à la fois l'absence de frais d'abonnement et le principe que l'intelligence devrait être disponible sans dépendance à une infrastructure externe.

LiberaGPT est développé et publié par 5N6 LTD, une société britannique de logiciels enregistrée en Angleterre et au Pays de Galles.
