Flux1-Hybrid: Blending Dev's Realism with Schnell's Speed and Improved Prompt Adherence

Introduction:

Introduce your new diffusion model, highlighting its unique combination of realism, speed, and prompt adherence. Emphasize the benefits of using this model compared to other popular options like Dev and Schnell. it is perfect for users with limited computational resources who want to generate high quality images quickly.

Key Features:

4-step generation: Produces high-quality images in a fraction of the time compared to many other models.

Enhanced prompt adherence: Accurately captures the nuances of your prompts, resulting in more relevant and creative outputs.

Photorealistic quality: Achieves a level of realism that rivals Dev, while maintaining the versatility of Schnell.

CFG sensitivity: Provides fine-grained control over image generation through the CFG scale.

Analysis:

Prompt adherence: Our hybrid model consistently generates images that closely align with the provided prompts, outperforming Dev in this regard.

Realism: While Dev excels in photorealism, our model offers a more balanced approach, combining realistic elements with artistic flair.

Efficiency: The 4-step generation process makes our model significantly faster than Dev, without compromising on quality.

Versatility: Our hybrid is capable of producing a wide range of styles, from photorealistic portraits to abstract art.

Inference Time: Intel I5, 32 RAM, Nvidia 3060 12Gb, 45s (same settings, dev, 2m42s). tested with SwarmUI working on ComfyUI.

Caveat: The time of generation of images is measured with the model preloaded. From the click on generate button until the image ends. The model first makes an initial image, which is then refined in 4 steps, the 4 steps last much less than the generation of the initial image.

How to Use:

Recommended settings: Random seed, CFG=1 (0.8-1.2) range, sampler: Euler, Scheduler: Normal/Simple, in the examples Resolution: 5:8 (768x1216).

Clip,T5 encoders and vae are incorporated with Kijai Flux1-FP8. It´s recommended to use --lowvram interface flag to pass the handle of encoders to CPU

Limitations: the range of CFG for non distorted images is narrow. Realistic images are affected by CFG, abstract and landscapes not the same, so for images without humans, in dark images you can raise CFG, and for shinny ones you can lower it a bit more CFG (0.6-1.4). There´s no FluxGuidance as in dev model. Text is an issue to solve.
