Frequently Asked Questions
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.
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.
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.
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.
