Proton<\/a>, l’entreprise technologique genevoise sp\u00e9cialis\u00e9e dans les services ax\u00e9s sur la protection de la vie priv\u00e9e, int\u00e8gre Apertus<\/a> 1.5 \u00e0 son assistant IA Lumo<\/a>, mettant le mod\u00e8le \u00e0 disposition, en option, de dizaines de millions d’utilisateurs. Dans le cadre de ce partenariat, Proton partagera les retours des utilisateurs avec l’\u00e9quipe de recherche d’Apertus afin de contribuer \u00e0 l’am\u00e9lioration du mod\u00e8le.<\/p>\n\n\n\n

Apertus a \u00e9t\u00e9 cr\u00e9\u00e9 par des chercheurs de l’EPFL<\/a> et de l’ETH Zurich<\/a> avec des institutions partenaires, et a \u00e9t\u00e9 lanc\u00e9 en septembre 2025<\/a> en tant que mod\u00e8le multilingue enti\u00e8rement ouvert. Entra\u00een\u00e9 sur le supercalculateur Alps du Centre Suisse de Calcul Scientifique (CSCS<\/a>) et publi\u00e9 sous licence open source Apache 2.0, il documente de mani\u00e8re transparente ses donn\u00e9es d’entra\u00eenement, son code source et son processus de d\u00e9veloppement, permettant aux chercheurs, aux institutions publiques et aux entreprises de l’examiner, de l’adapter et de le d\u00e9velopper. Le mod\u00e8le a \u00e9t\u00e9 entra\u00een\u00e9 sur des donn\u00e9es publiquement accessibles, respecte les refus de collecte des sites web, y compris de mani\u00e8re r\u00e9troactive, et est con\u00e7u pour retirer \u00e0 grande \u00e9chelle les donn\u00e9es personnelles de ses donn\u00e9es d’entra\u00eenement.<\/p>\n\n\n\n

Des retours issus de l’usage r\u00e9el<\/h4>\n\n\n\n

Les retours de millions d’utilisateurs constituent l’une des principales ressources sur lesquelles s’appuient les grandes entreprises d’IA pour am\u00e9liorer leurs mod\u00e8les, alors que les mod\u00e8les ouverts d\u00e9velopp\u00e9s en milieu acad\u00e9mique b\u00e9n\u00e9ficient rarement de contributions comparables. Gr\u00e2ce \u00e0 l’int\u00e9gration dans Lumo, l’\u00e9quipe d’Apertus aura pour la premi\u00e8re fois acc\u00e8s \u00e0 des retours volontaires issus d’un d\u00e9ploiement r\u00e9el, fournis par des utilisateurs ayant donn\u00e9 leur consentement \u00e9clair\u00e9.<\/p>\n\n\n\n

Comme toutes les conversations dans Lumo, les \u00e9changes avec Apertus 1.5 sont prot\u00e9g\u00e9s par un chiffrement \u00e0 acc\u00e8s z\u00e9ro et restent priv\u00e9s. Les utilisateurs peuvent choisir de transmettre des retours anonymis\u00e9s sur les r\u00e9ponses du mod\u00e8le, qui peuvent ensuite \u00eatre partag\u00e9s avec l’\u00e9quipe de recherche pour soutenir son d\u00e9veloppement.<\/p>\n\n\n\n

Depuis son lancement, Apertus est de plus en plus pass\u00e9 de la recherche au d\u00e9ploiement concret. Parmi les organisations qui ont d\u00e9ploy\u00e9 Apertus 1.5 ou l’ont int\u00e9gr\u00e9 \u00e0 leurs offres figurent Swisscom, Infomaniak, OnPrem.ai, Stepping Stone, Safe Swiss Cloud, Mono.chat, Helvetra, Featherless.ai, Public AI et AI Potluck.<\/p>\n","protected":false},"excerpt":{"rendered":"
