12 What is fine-tuning in Stable Diffusion?

Fine-tuning trains Stable Diffusion on your images to generate specific styles, characters, or products. Methods include LoRA, DreamBooth, and textual inversion. Requires some technical knowledge but enables unique capabilities.

13 Can I still use a pay-per-image credit system with Stable Diffusion?

For the official DreamStudio platform, Stability AI has shifted to a subscription-only model according to user reports from September 2026. However, you can still use Stable Diffusion without subscriptions by running the Open Source (Self-Hosted) version for free, or through the Stability AI API which uses pay-per-use pricing. The DreamStudio subscription costs $10/month based on current pricing.

14 What happens to my purchased credits if DreamStudio changes pricing?

Multiple users report that Stability AI retroactively changed the credit cost per image from 1.25 credits per image (5 credits for 4 images) to 8 credits per image in August 2026. This effectively devalued existing credit balances by approximately 60% without compensation or advance notice.

15 How do I cancel my Stable Diffusion subscription?

Users report significant difficulties canceling subscriptions, with some experiencing continued charges even after account deletion. There appears to be no self-service cancellation option in the dashboard. Multiple users had to contact their credit card companies to block charges, as support requests went unanswered for weeks. If you need to cancel, document your cancellation request via email and be prepared to dispute charges with your bank.

16 Do I get charged if Stable Diffusion produces a bad image?

Yes. Users report that credits are consumed for every generation attempt regardless of output quality. If the AI produces an unusable result, incorrect content, or fails to follow your prompt, you still lose the credits with no refund option. Users report this can waste 10-30% of purchased credits on failed attempts.
