About Stability AI Upscale Conservative
Upscale Conservative is Stability AI's enlargement service that stays close to the source picture. It raises resolution and adds modest enhancement without reinterpreting the content. Stability's service group also includes Fast and Creative upscalers; the conservative one is meant for cases where the original must remain recognisably the same. It accepts a prompt, which helps steer the added detail.
Where it works well
- It aims to keep the original content intact, which matters for product shots and portraits that must stay faithful.
- A prompt can describe the subject to guide the extra detail.
- Gives more careful enhancement than a plain enlargement step.
When to choose another model
- It will not repair a badly damaged image or invent missing content; the Creative upscaler is the one that reinterprets.
- For routine batches with no prompt, Upscale Fast is the simpler option.

FAQ
What is Stability Upscale Conservative?
An image enlargement service from Stability AI that emphasises keeping the source content. It adds resolution and modest enhancement without a substantial creative reinterpretation, which makes it the faithful option among Stability's upscalers.
Does it take a prompt?
Yes. You send an input image plus a prompt that describes the subject, and the prompt steers the detail that gets added. The source content is kept; this is not a way to change what the picture shows.
How does it differ from Upscale Fast?
Fast is a straightforward enlargement step that takes no prompt. Conservative accepts a prompt and does more careful enhancement while staying faithful to the source.
When should I use a Creative upscaler instead?
When the input is very low quality or you want the model to reimagine textures and details. Conservative is for results that must stay faithful to the original, such as product photos, portraits, and scans of existing artwork.
Does it work on text prompts alone?
No. It requires an input image to enlarge. It is an image-to-image step with no text-to-image capability, so generate the picture first with another model and then pass it here for resolution.
How much does Stability AI Upscale Conservative cost?
On TokenLab, Stability AI Upscale Conservative costs $0.40 per image. The pricing table above shows the full breakdown. Rates depend on the billing unit, specification, and usage. Compare matching conditions in the model's detailed pricing; a single rate does not determine the total cost.
