## Frequently Asked Questions

### What does the Raw output mode do?

The Raw parameter switches the model from its default vibrant, high-contrast studio look to a documentary photographic style. When enabled, it renders organic skin textures, fine facial pores, soft volumetric lighting, and subtle filmic grain while preventing the plastic, over-smoothed appearance common in AI imagery.

### How does native 4MP resolution compare to using an upscaler?

Native 4-megapixel generation synthesizes full 2K resolution directly inside the rectified flow-matching transformer in approximately 10 seconds. This avoids the blur, texture repetition, and synthetic hallucination artifacts introduced by secondary upscaler pipelines.

### How do I generate accurate text and typography in images?

Enclose your exact target words in quotation marks within your descriptive prompt (for example, a sign reading \\"OPEN 24 HOURS\\"). The model excels at typographic layouts, storefront lettering, and poster titles when text is clearly delineated.

### When should I avoid using FLUX1.1 [pro] Ultra?

Avoid this model when you need rapid low-cost exploratory sketching, fine-tuned local LoRAs or ControlNets, or negative prompt steering. It can also produce anatomical inconsistencies during complex hand interactions like intertwined fingers or handshakes.

### Who created FLUX1.1 [pro] Ultra and when was it released?

FLUX1.1 [pro] Ultra was developed by Black Forest Labs and introduced in November 2024 as the high-resolution flagship tier of the FLUX1.1 family.
