Comment fonctionne la generation d'images par IA
Concepts cles de la creation d'images par IA.
Processus de diffusion
Les generateurs d'images IA partent d'un bruit aleatoire et le reduisent progressivement pour former une image coherente, guidee par votre prompt textuel. Ce processus prend generalement de 3 a 30 secondes selon le modele.
Texte vers image (T2I)
Decrivez une image en langage naturel et l'IA la genere. Les modeles modernes comprennent la composition, l'eclairage, le style et les concepts abstraits a partir du texte seul.
Controle du style
Generez des images dans n'importe quel style visuel : photorealiste, peinture a l'huile, anime, rendu 3D, aquarelle ou pixel art. Le style est controle par des mots-cles dans le prompt ou les parametres du modele.
Haute resolution
Les meilleurs modeles produisent des images en 1024x1024 ou plus. Midjourney v7 prend en charge la sortie en ultra haute resolution, et Flux 2 excelle dans le rendu precis de texte dans les images.
Inpainting et edition
Modifiez des zones specifiques des images generees. Supprimez des objets, changez les arriere-plans ou ajustez des details tout en preservant le reste de l'image.
Options open source
Flux 2 (Apache 2.0) et Stable Diffusion (poids ouverts) peuvent etre auto-heberges gratuitement. L'acces API coute a partir de 0,003 $ par image via des fournisseurs tiers.
