Stability AI is the company behind Stable Diffusion: open, self-hostable image generation models (free under the Community License for revenue under $1M/year) plus a prepaid-credit API and enterprise Brand Studio for review/approval workflows.
Self-host free for qualifying commercial use. API: 25 free credits on signup, 1 credit = $0.01, images cost 2.5-6.5 credits depending on the SD3.5 tier (roughly $0.025-$0.065/image). Stable Audio 3 (May 2026) added stereo audio generation.
Developers and technical teams who want to self-host or fine-tune an open image model (via LoRA) rather than depend on a closed, hosted-only generator.
This is model infrastructure, not a polished consumer app: expect to use it via API or a self-hosted UI (like ComfyUI or Forge) rather than a simple web interface, unlike most other tools in this category.
