Recraft Crisp Upscale
Recraft Crisp Upscale: a sharp 2× upscale that does not invent new details.

Prices and parameters come from the same catalog as the price above; this is not a benchmark, it is comparable billing terms.
Limits
Pricing is flat — $0.0034 per image, regardless of prompt length.
There is no subscription: every successful request is billed at the price above, and a failed one is not billed at all. That price is already 15% below the vendor's official one — the official price is shown struck through next to it so it can be checked. No Recraft account of your own is needed, and no VPN: requests go to api.altrouter.ai and we make the upstream call.
Rate limiting is shared across models and counted per key: 600 requests per minute by default, and a 429 with retry-after: 60 above it. An individual key can get its own limit and a spending cap per day, week, month or lifetime in the dashboard.
When to pick Recraft Crisp Upscale, and when a neighbour
The dearer neighbour is Recraft Remove Background: $0.0085 per image, or 2.5× the price. On catalog parameters it offers the same capabilities and the same order of context, so the premium is only justified if Recraft Crisp Upscale falls short on your own task.
Guessing is more expensive than checking: the table above is prices and parameters, not a benchmark, and it cannot tell you which model does better on your own prompt. Switching costs one line — the model id in the request changes, the base_url and the key stay — so running both on your own data takes minutes.
