Diffusion4Mac Local Flux macOS App UI Mockup

Designed for Next-Gen Local AI

Experience the raw performance of a native Flux Klein Apple Silicon GUI combined with flexible cloud integrations.

Local Power

Achieve sub-second generations directly on your machine. Fully optimized for Apple Silicon GPUs and Neural Engines using FLUX.1-schnell and FLUX.2 [klein].

Hybrid Flexibility

Seamlessly transition between offline workflows and cloud-based models. Use the Gemini Studio tab for premium fallback to Google's Imagen 3 and prompt engineering.

Onboard Intelligence

Unleash local prompt enhancements and image assessments with the built-in, local Gemma-powered AI Assist and Prompt Designer. Run Gemma locally for purely local prompting and image assessment completely offline.

Advanced Control

Fine-tune your generations with multi-LoRA stacking. Import custom weights safely with automatic trigger word extraction and required keyword validation.

An All-in-One Desktop AI Studio

Diffusion4Mac packs high-performance capabilities into a clean, unified sidebar interface.

Text to image

Generate high-quality images from text descriptions locally using FLUX models.

Image to image

Transform existing images using structural guidance and prompt descriptions.

Inpainting

Add, remove, or modify objects within a specific region of your images seamlessly.

Upscaler

Increase the resolution and add fine detail to low-resolution generations locally.

Prompt Designer

Design complex, artistic FLUX prompts using local vision models.

LoRAs

Manage, validate, and apply custom fine-tuning weights with trigger word checks.

Gemini Studio

Access cloud-based frontier AI generation utilizing Imagen 3 and Gemini 2.5 Flash.

Engineered to Run Flux Locally on Mac

Diffusion4Mac is compiled natively to harness Metal Performance Shaders (MPS) and Apple Silicon’s unified memory architecture.

  • Fully Offline: Run Flux locally on Mac without internet requirements.
  • Zero Telemetry: Complete privacy. Your generations never leave your hardware.
  • Resource Optimized: Low RAM configurations enable FLUX on baseline Macs.
  • Model Formats: Supports .safetensors checkpoints, custom VAEs, and custom LoRA files.
