This is an excerpt from our longer guidance tutorial. As it is a frequently asked question, we wanted to help make it easier to find:

Has this ever happened to you?

nope, this isn’t normal. but it’s a common issue and an easy fix


When garbled faces appear, it either means (1) the AI model doesn’t have enough information on the topic (2)  it found the prompt confusing or (3) needs lower guidance or (4) all of the above. Luckily, it’s a quick fix.

Now’s a good time to teach you Guidance. It’s a hidden parameter of /brew and /render, and it has a number range from -50 to 50. A typical range is 6-10. Guidance tells the AI how much freedom is has to follow your instructions.  So the quick fix is to make sure our prompt is as clean as possible to understand, and to lower guidance.  Use this template:

The visual model also matters. Concepts like Real vision 1.3, Deliberate, Hassansblend, Analog and some others are great at celebrities from past years. If someone is recently famous, you’re better off uploading a photo of them and using a strong remix prompt if the AI models have no idea who they are yet.

Trouble prompt:

/render /size:800×600 full body shot of (Kate Bush 21 years old) wearing a wet blue (sku-mizu) swimsuit, doe eyes, studio lighting, (crouching on a bed) <realvis3>

This says it MUST be a 21 year old photo of Kate. Let’s decouple that. We can emphasize the person and be more flexible on other aspects, and lower the guidance, so it has more wiggle room to create the image.


/render /portrait /guidance:4 full body photograph of ((Kate Bush)) young 21 years old wearing a wet blue (sku-mizu) swimsuit, doe eyes, studio lighting, (crouching, on a bed, bedroom scene, indoors) <realvis13>

Tada! She’s perfect.

But remember, AI doesn’t always get anatomy right. After you get your guidance down right, use a style like the one in the realistic people tutorial.

Then use /facelift to AI upscale the pixels 4x, which also smoothens lines

And upscaled once to x1024

And upscaled again to x2048

Greater detail is possible by starting at a higher resolution, and making the prompt more specific about skin imperfections, shadows, and so on.
