💡 Personal Tips
Stable Diffusion is unbeatable if you have a decent GPU (8GB+ VRAM) and want full control. ComfyUI is the best interface for power users. The community ecosystem is massive — CivitAI has thousands of fine-tuned models. Setup takes 30-60 minutes the first time, but then you get unlimited, free, private image generation forever.
