Unmatched customization through LoRA fine-tuning, ControlNet, and custom model training
No content restrictions when self-hosted, giving artists full creative freedom
Massive community with thousands of pre-trained models, extensions, and tutorials

Default output quality is inconsistent without careful prompting and model selection
No built-in user-friendly interface - you need third-party tools like ComfyUI
Stability AI as a company has faced financial instability, raising concerns about future development
