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.
SwarmUI
SwarmUI is a modular web interface for generating images with AI, with support for video and some audio models. Its listed image models include Krea 2, Stable Diffusion, and Flux; video examples include MiniMax H3, Wan, and LTX-2, and ACE-Step is listed for audio. A beginner-oriented Generate tab sits alongside a Comfy Workflow tab that exposes the raw graph for advanced work. SwarmUI can install ComfyUI and use it as a backend, or connect to AUTOMATIC1111. Its tools include an image editor, automatic workflow generation, and Grid Generator, and users can add extensions and custom node packs. By default, it runs on the user's own computer and says it collects no user data. Windows, Linux, and M-Series Mac are listed as compatible; a modern GPU is required, with Nvidia RTX 30xx or newer recommended. Cloud GPU options include a free Google Colab option and templates for Runpod and Vast.ai. SwarmUI is free and open source under the MIT License.
