FAQ
Is there a free AI image generator?
Yes — Oakgen's free tier includes 1,000 credits (~40 FLUX Pro images or 120 Stable Diffusion runs) with no credit card. For unlimited free generation locally, run open-source Stable Diffusion 3.5 on a GPU with 8GB+ VRAM.
Can I use AI-generated images commercially?
Yes on every paid Oakgen plan. Generated images from FLUX, Imagen, Ideogram, and Stable Diffusion include commercial rights. Check each tool's standalone license if you use them outside Oakgen — terms vary.
