Stay free if you only need download all models free and unlimited image generation. Upgrade if you need replicate, runpod, vast.ai hosting and different pricing models. Most solo builders can start free.
Why it matters: SD 3.5 Large requires 24GB VRAM ($2000+ GPU) for optimal local performance
Available from: Stability AI API
Why it matters: Installation and setup demands technical expertise—expect 2-4 hours troubleshooting on first attempt
Available from: Stability AI API
Why it matters: Image quality varies dramatically based on model choice, prompts, and parameter tuning
Available from: Stability AI API
Why it matters: Community models may have inconsistent licensing terms despite base model being open-source

Why it matters: Text rendering in images lags behind DALL-E 3 and Midjourney for typography-heavy designs

SD 3.5 Medium requires 10GB VRAM (RTX 4070/4060 Ti minimum). Large needs 24GB VRAM—only RTX 4090 or RTX 50 series handle it well locally. Cards with less VRAM will use system RAM, making generation extremely slow.
Midjourney costs $30/month for unlimited generation. SD API costs $0.04-$0.08/image—breaking even at 375-750 images monthly. Local hosting costs GPU hardware ($800-2000) but provides unlimited generation afterward.
The base SD 3.5 model is free for commercial use under Stability AI's license. However, community models on Civitai may have different licenses—check each model's specific terms before commercial deployment.
Plan 2-4 hours for first successful installation. Windows users need Python, Git, and proper CUDA drivers. Mac users require M-series specific builds. Linux typically works smoothest but still requires command-line comfort.
Choose Stable Diffusion for privacy-sensitive projects, high-volume generation (500+ images/month), or when you need specific style control through custom models. Pick Midjourney for casual use, consistent quality without technical setup, or when you need results immediately.
Start with the free plan — upgrade when you need more.
