Pros & cons
- +Only major open-source image generator — total control over the pipeline
- +Massive community of fine-tunes (Civitai etc.) for specialized styles
- +Self-hosting eliminates per-image costs at scale
- −Setup overhead is real — local hardware + Comfy/Automatic1111 learning curve
- −Baseline quality trails Midjourney for aesthetic-default work
- −Commercial licensing for fine-tunes gets murky
