In their own words
FLUX
FLUX is a set of AI models from Black Forest Labs for creating and editing images and video. FLUX 3 can make video with synchronized audio from text or images, or continue a clip, with a maximum length of 20 seconds. FLUX.2 generates and edits images up to 4 MP, with multi-reference editing, hex color control and text rendering. FLUX Tools add outpainting, object erasing, virtual try-on, video upscaling and deblurring. Access options include a browser playground, API and downloadable weights for self-hosting. Platforms listed are API, Linux, macOS, self-hosted, web and Windows. There is a free plan; the listed pay-as-you-go FLUX.2 [klein] 4B option is $0.01, paid once, with additional megapixel and reference-image charges. API use includes full commercial rights without a separate license; rights for open-weight models depend on their license. Submitted prompts, uploads, tasks and outputs may be used to train and improve models, with an email opt-out route.
Stable Diffusion WebUI Forge
Stable Diffusion WebUI Forge is a free, open-source platform built on Stable Diffusion WebUI for image generation and editing. It supports text-to-image creation, reference images, and image editing, with PNG, JPG, JPEG, WebP, AVIF, and GIF listed as output formats. The project aims to ease development, manage resources, speed inference, and explore experimental features. Its interface is based on Gradio, and the README offers a one-click installation package that includes Git and Python. Windows launch scripts, shell scripts, a macOS environment script, and source installation instructions are listed. Forge includes GPU memory management and components such as LoRAs, ControlNets, IP-Adapters, Instant-IDs, reference-only methods, and extensions. Several Flux BitsandBytes and GGUF variants are natively supported, with GPU weight and swap controls; some variants support LoRA. The README lists txt2img and img2img API endpoints as normal, while improved Flux support is pending. The project is described as under construction, so its documentation, interface, and functionality may change. Its license is AGPL-3.0.
