What is Flux?
Flux is a new AI image generation model by Stability AI, designed as a successor to SDXL. It is not just an upgrade but an entirely new architecture that moves away from the latent diffusion model (LDM) used in SDXL. Flux is designed to be:
- Faster: It generates images in a single step or very few steps, unlike SDXL, which requires iterative denoising.
- Higher Quality: It can create more photorealistic and detailed images.
- More Efficient: Uses a different approach to image generation, likely inspired by diffusion transformers.
However, since Flux is still in early development, details about its exact architecture, local usage, and model weights remain unclear.
What is SDXL?
SDXL (Stable Diffusion XL) is the current best open-source image generation model by Stability AI. It uses a latent diffusion model (LDM), meaning it starts with noise and refines the image step by step. SDXL is:
- Highly Customizable: Can be fine-tuned with LoRAs, ControlNet, and other extensions.
- Works Locally: Runs on PCs using Fooocus, ComfyUI, A1111 (AUTOMATIC1111), etc.
- Supports Inpainting, Outpainting, and Text-to-Image Tasks.
Which One is Better?
- For Local Use Right Now → SDXL (because it is available and optimized for local generation).
- For Future Advancements → Flux (if it delivers on its promises of speed and quality).
If Stability AI releases local PC-compatible versions of Flux, then it might become a better choice over SDXL, but as of now, SDXL is the best open-source option.
Can You Use Flux Locally Like Fooocus (SDXL)?
- Right now, no. Flux has not been released for local use yet.
- In the future? Maybe. If Stability AI releases model weights for local inference, tools like Fooocus or ComfyUI might support it.
For now, if you need fast and high-quality AI image generation on your PC, Fooocus with SDXL is still your best option.
