Hidden Costs Breakdown

1

Credit Pricing Changes on Purchased Credits

high overage

Users who purchased credits upfront experienced retroactive price increases, with costs jumping from 5 credits for 4 images to 8 credits per image. This effectively devalued existing credit balances without warning or compensation.

trustpilot

Some time in August, I found myself burning through credits (8 per image) when I was used to being charged 5 credits for 4 images. This was because DreamStudio changed the pricing, including on previously purchased credits.

2

Unexpected Subscription Conversion

high addon

DreamStudio (Stability AI's hosted platform) has transitioned from a credit-based model to a subscription-only model, converting users mid-usage and billing for unused credits without refund.

trustpilot

Paid for "credits" to be able to generate images: the service worked fine for a couple days, then stopped working and started to ask for a $9/month subscription.

trustpilot

they are now going to a subscription-only model (you pay whether you use it or not) so I will not be doing anything further with them once I use up my credits.

3

Failed Generation Charges

medium overage

Users are charged credits even when the AI produces unusable or incorrect outputs. Every generation attempt costs money regardless of quality, with no refunds for failed results.

trustpilot

The prompt adherence is abysmal. A prompt to turn a model to show side profile creates a a model with no shirt on. Also you will burn through the credits. There is no feedback to correct the error.

trustpilot

Every mistake costs money. Even the videos it produces are completely absurd.

4

Continued Billing After Account Deletion

critical support

Multiple users report being charged even after canceling subscriptions or deleting their accounts, with no way to stop recurring payments through the platform.

trustpilot

They've charged me money after I've deleted account from there. Bunch of thieves, they've didn't reply for a mail with complaining about it.

trustpilot

I tried them for one month and then decided to go with a different provider... But they trying to charge me once a week... I blocked them on my credit card but I can still see the attempts.

5

Credits Lost Without Recourse

critical overage

Multiple users report purchasing credits that subsequently failed to work, with no response from customer support and no refund process available. Credits may show on account but API calls return negative balances.

trustpilot

Lost the money I paid, No answers from support more than month.... I paid again, I see the new credits on my account, but anyway APi call shows me "-0.5" credits on y balance and service doesn't work.

trustpilot

I paid for the Dream Studio image generator service a few times. It does work good, but recently I paid it again and the credits didn`t loaded, I had sent tickets with a screenshot of the payment to customer service but they hasn`t even repplied.

6

No Refunds for Failed or Poor-Quality Generations

medium support

Credits are consumed even when the model ignores prompts or produces unusable outputs. There is no mechanism to get credits back for failed or incorrect generations.

trustpilot

Stability.ai Dreamstudio charges you for images even when it totally disregards your instructions, and there is no way to get the credits refunded.

Every mistake costs money.
