Midjourney offers a Personalization feature, introduced as a default element of V7 (April 2025), that learns a user's visual preferences by having them rate images and then subtly adjusts future AI-generated images to match their individual aesthetic taste. Users can turn this feature on or off at any time.

To unlock Personalization, users rate approximately 200 image pairs (taking roughly five minutes), building a 'Personalization Profile.' Once active, the --p parameter is appended automatically to prompts, and the AI generation model adjusts its outputs toward the aesthetic patterns the user selected. Multiple custom profiles can be created for different style preferences. Personalization is compatible with model versions V6, V7, and V8.1. According to Midjourney's official announcement when V7 became the default model in June 2025, personalization profiles are preferred by 85% of users over non-personalized outputs. Liking images from other users on the community Explore page also influences a user's global profile.
