Frequently asked questions

Can Stable Diffusion generate professional headshots?
Stable Diffusion can generate photorealistic portraits, but producing a headshot that looks like a specific person requires training a LoRA model on your face — a process that takes hours and requires technical knowledge. ThePortraitOS handles all of this automatically using 240+ facial landmarks.
Is Stable Diffusion free?
Self-hosted Stable Diffusion is free if you have the hardware. Cloud-based services cost $20+/month. ThePortraitOS is $29 one-time for 20 professional portraits with no GPU required.
Which is easier for a professional?
ThePortraitOS: upload one selfie. Stable Diffusion: install software, download models, train LoRA on your face, engineer prompts, iterate. For professional headshots, the choice is clear.
Is self-hosted Stable Diffusion private?
Self-hosted Stable Diffusion is as private as your hardware setup. ThePortraitOS is Swiss-hosted with guaranteed GDPR compliance — no self-hosting required.
