Frequently Asked Questions
Stable Diffusion models are free to download and run on your own hardware with no usage limits. Running locally requires a GPU with at least 4GB VRAM. DreamStudio, the official cloud platform by Stability AI, uses a credits system starting with free credits on sign-up.
Midjourney produces more consistently polished results with minimal effort — better for users who want great images without technical setup. Stable Diffusion gives more control, costs nothing to run locally and has no content restrictions — better for developers, artists with specific needs and power users. Midjourney for ease; Stable Diffusion for power and freedom.
For basic Stable Diffusion use, an NVIDIA GPU with 4GB+ VRAM works (RTX 3060 or similar). For SDXL and higher-resolution generation, 8GB+ VRAM is recommended. NVIDIA cards work best due to CUDA support — AMD cards work but require additional setup.
