This new AI image generator just broke reality

Key Concepts

• Flux Crea Dev: An open-source AI image generator, an upgrade to the original Flux model, designed to generate more realistic and less "plasticky" images.
• Flux Dev: The original Flux model, noted for generating images that can appear overly polished and artificial.
• ComfyUI: A node-based interface for creating and running Stable Diffusion workflows, utilized here for local installation and customization of Flux Crea Dev.
• VRAM: Video RAM, the memory on a graphics card, important for running AI models like Flux Crea Dev. Lower VRAM options (FP8, GGUF) are discussed.
• Non-commercial License: A license restricting commercial use of Flux Crea Dev, but allowing free use for personal projects.
• FP8, GGUF: Compressed model formats for Flux Crea Dev that reduce VRAM requirements, enabling use on systems with less powerful GPUs.
• Positive Prompt: A text description guiding the AI to generate specific elements in the image. Flux Crea Dev does not utilize negative prompts.
• Steps (in KSampler): The number of denoising iterations the AI performs, affecting image quality and processing time.
• CFG Scale: Determines how strictly the AI adheres to the prompt. Higher values lead to more literal interpretations.
• Seed: A starting point for image generation. Using the same seed and settings will reproduce the same image.
• One 2.2: An open-source video model that is also very good at generating images.

Flux Crea Dev: A Realistic Open-Source Image Generator

Overview

The video introduces Flux Crea Dev, a new open-source AI image generator that aims to produce more realistic images compared to its predecessor, Flux Dev. Flux Crea Dev addresses the "plasticky" and overly polished look often associated with AI-generated images by introducing imperfections and a more natural aesthetic.

Comparison with Flux Dev: Examples

The video showcases several examples comparing image generations from Flux Crea Dev and Flux Dev, using identical prompts. The key differences highlighted are:

• Amateur Photo of a Woman: Flux Crea Dev generates a grainy, noisy, and slightly blurry image, resembling a real amateur photo. Flux Dev produces an overly polished image with plasticky skin and professional-looking background blur.
• Amateur Photo of a Nerdy Woman: Flux Crea Dev creates a more realistic depiction, including freckles and messy hair. Flux Dev struggled to generate a realistic image and failed to include braces as specified in the prompt.
• Woman Riding a Bus: Flux Crea Dev produces an image with chromatic aberration and imperfections, resembling a real photo. Flux Dev's image is too perfect, with saturated colors and plasticky skin.
• Yearbook Page: Flux Crea Dev's output looks more like an actual yearbook page, while Flux Dev's image has overly saturated colors.
• People Dancing at a Nightclub: Flux Crea Dev's image appears natural and realistic, with only minor anomalies like extra fingers. Flux Dev's image looks too perfect and artificial.
• Urban Rooftop Garden: Flux Crea Dev generates a realistic image of a cat and succulents. Flux Dev's image has a plasticky appearance.
• Street Vendor in Vietnam: Flux Crea Dev's output looks like a genuine photo, while Flux Dev's colors are too saturated and the image lacks realism.
• Elderly Women Playing Chess: Flux Crea Dev produces a highly realistic image, except for some inaccuracies in the chess pieces. Flux Dev's image has a plasticky vibe.
• Skateboarder: Flux Crea Dev generates a more realistic image compared to the original model.
• Cars Racing: Flux Crea Dev accurately renders the car models mentioned. Flux Dev could not consistently generate all the cars listed.
• Teenage Woman Holding a Note: Flux Crea Dev generates a realistic low-quality selfie, while Flux Dev produces an overly perfect image.
• Grizzly Bear Catching Salmon: Flux Crea Dev's image is more detailed and realistic, while Flux Dev's looks cartoony.
• Spectral Tarsciers: Both models failed to accurately generate images of spectral tarsciers.
• Dogs Dressed as World Leaders: Flux Crea Dev lacks ethnic diversity.
• Snowy Mountain Peak: Flux Dev's colors look too saturated and too blue.
• Security Camera Footage: Flux Dev performs surprisingly well in this scenario.
• Ballerina: Flux Crea Dev understood most of the long prompt, but the elephant was levitating. Flux Dev was missing multiple elements from the prompt.
• Movie Posters: Both models are good at generating movie posters, but it is a tie.
• YouTube Video Search: Flux Crea Dev correctly showed the search results, unlike Flux Dev.
• Long Snippets of Text: Flux Crea Dev could generate more text, unlike Flux Dev.
• Handstand: Neither model can generate this very well.
• Palms and Soles of Feet: Flux Crea Dev performs well, but is missing a toe.
• Hands Making a Star Shape: Neither model could generate this well.
• Marketplace in 3D Pixar Animation: Flux Crea Dev looks slightly nicer and more detailed.
• Anime at McDonald's: Flux Crea Dev understood most of the anime characters, but had flaws with some fingers.
• Manet Style Impressionist Painting: Flux Crea Dev is closer to this style than Flux Dev.
• Pencil Sketch: Both models perform well here.
• Whale Swimming Through Clouds: Flux Crea Dev's image is more realistic.

The video includes a sponsored segment for Loveart, an AI design agent. Loveart automates the design process, creating images, videos, and audio for various purposes. It can generate posters, media kits, app designs, and video commercials. Examples include:

• Creating posters from a speaker's image.
• Generating a full brand kit (logos, color palettes, typography, packaging, website) from an image.
• Creating a commercial video and marketing materials from images.
• Designing a Vogue poster from a photo.

Local Installation with ComfyUI (Step-by-Step)

The video provides a step-by-step guide for installing and running Flux Crea Dev locally using ComfyUI, focusing on a method that accommodates lower VRAM GPUs.

1. Install ComfyUI: Assumes ComfyUI is already installed. Recommends checking a previous video for a full ComfyUI tutorial.
2. Download Models:
   • Flux Crea Dev Model: Choose between the full .safetensors file (for sufficient VRAM) or the FP8 scaled version (recommended for lower VRAM, under 12 GB). Also mentions GGUF models for even lower VRAM (as low as 6 GB), but notes a potential quality sacrifice due to compression. Place in ComfyUI/models/diffusion_models.
   • Clip L File: Download and place in ComfyUI/models/text_encoders.
   • T5XXL File: Choose the FP8 version (recommended for GPUs with less than 32 GB VRAM). Place in ComfyUI/models/text_encoders.
   • AE.safetensors File: Download and place in ComfyUI/models/VAE.
3. Update ComfyUI: Open ComfyUI, click "Manager," and update ComfyUI to ensure the latest components. Restart ComfyUI after the update.
4. Download Workflow: Download the official Flux Crea Dev workflow file and drag and drop it onto the ComfyUI interface.
5. Select Models in Workflow: In the ComfyUI workflow, select the downloaded models in the appropriate dropdown menus for each component (Flux Crea Dev FP8, clip L, T5XXL FP8, AE.safe tensors).
6. Configure Settings: Adjust width, height, and batch size as desired.
7. Adjust KSampler Settings: Adjust seed, steps, CFG Scale, and Sampler name as desired.
8. Enter Prompt: Enter a positive prompt in the designated area. There is no negative prompt for Flux Crea Dev.
9. Run Workflow: Click "Run" to generate the image.
10. Locate Output: The generated images are saved in ComfyUI/output/Flux Crea.

Flux Crea Dev vs. One 2.2

The video mentions One 2.2, primarily a video model, as another potentially superior open-source image generation option. While One 2.2 shows promise, the video notes a lack of consensus on optimal settings for image generation, delaying a full review until a more standardized approach emerges.

Conclusion
