About
FLUX 3 Image Klein is an image-generation model from Black Forest Labs for developers and creative teams. It creates images from text prompts and supports instruction-based image editing, reference-image guidance with up to 10 images, and output at resolutions up to 4K. The 5.6-billion-parameter model is available through the Black Forest Labs API and as downloadable weights for local inference. Base and step-distilled variants support different workflows, with additional quantized formats for local deployment. Use it for creative production, design exploration, prototyping, and image-generation features in applications. Local and commercial use are subject to the model license. API usage is charged per generated image, with pricing varying by resolution.

About
Logen is a Windows and Linux desktop application for AI image generation on a local computer. It combines project-based chat, model management, workflow tools, image galleries and full-resolution viewing. Its setup prepares ComfyUI for image rendering and Ollama for local prompt assistance. Users can organize generated images by project, adjust generation options, and work with supported ComfyUI workflows. The free tier includes local image generation with FLUX.1-schnell. The one-time Pro upgrade adds batch generation, additional models and custom workflow presets. Logen is intended for creators who want to run image-generation workflows on their own computer rather than use a cloud image-generation service. Windows 10/11 x64 and Linux x64 are supported, and an NVIDIA GPU is recommended. Initial setup and model downloads require an internet connection; image generation runs locally after setup.
