About Qwen3.5 Flash

Les modèles Flash de vision-langage natifs Qwen3.5 reposent sur une architecture hybride qui intègre un mécanisme d’attention linéaire à un modèle « mixture-of-experts » clairsemé, permettant ainsi d’atteindre une efficacité d’inférence supérieure. Par rapport à la série 3, ces modèles constituent un bond en avant en termes de performances, tant pour les tâches purement textuelles que pour les tâches multimodales, offrant des temps de réponse rapides tout en assurant un bon équilibre entre la vitesse d'inférence et les performances globales.
