What’s actually happening when you rate images in Midjourney?

1. Style Assessment > Personal Profiling

When you rate images, you're helping Midjourney’s algorithm understand aesthetic preferences — not learning your identity or personal data. It's not building a psychological profile of you; it's trying to tune the model to better reflect your visual taste.

2. How Does It Work?

Midjourney uses a proprietary image ranking and fine-tuning system, likely leveraging:

CLIP models (Contrastive Language-Image Pretraining): to match text prompts with image outputs.
Reinforcement learning from human feedback (RLHF)-style mechanisms: where your upvotes/downvotes influence future outputs globally or in small clusters of user preferences.

3. Your Ratings Are Not Just for You

The system doesn’t yet personalize images only for your account in a highly individualized way (like Netflix or Spotify). Ratings:

Help guide overall model improvements.
Might influence some user-specific stylization, especially with /prefer settings or style tuner features.
But it’s still mostly focused on improving how prompts translate to images across the board.

4. Does Midjourney “Learn You” Personally?

Not really — at least not in a deep AI/psychological way:

It doesn’t track or analyze your entire behavior history to build a profile.
It doesn’t store or fine-tune a custom model just for you.
However, when you use the Style Tuner, it does offer a more tailored "vibe" setting that reflects what you've chosen or rated — kind of like choosing a color palette or mood board for future outputs.

TL;DR: Rating images in Midjourney helps the system learn aesthetic preferences, not personal identity. It’s style-aligned optimization, not behavioral profiling. Think of it like training a visual taste buddy, not a spy.
