Crisp Upscale vs Seedream 5.0 Lite: Faithful 2× vs 2K Repaint

TL;DR

• Need pixel-faithful 2× upscaling? Use recraft/crisp-upscale ($0.004 per image, content and lettering untouched). Need redrawn 2K/4K-grade detail? Use seedream-5.0-lite/image-to-image ($0.035 per image, it repaints the whole frame).
• The hardest number: $0.004 versus $0.035 — nearly 9×; 1,000 images cost $4.00 versus $35.00 (full Crisp pricing on the pricing page).
• Both are live on HiAPI: the Crisp Upscale page and the Seedream 5.0 Lite page, one shared /v1/tasks, 200 free credits on signup.

At a glance

	recraft/crisp-upscale	seedream-5.0-lite/image-to-image
Per image	$0.004	$0.035
What it does	Faithful upscale: 2× on both axes, crisper edges, content unchanged	Generative repaint: redraws per prompt; 2K / 4K at the same price, 2K default
Input	One image (image_url)	One image (image_urls) + prompt
Prompt	None	Required
Scale / resolution	Fixed 2×	resolution parameter (2K / 4K same price; 2K default)
Risk	Near zero: nothing changes	Repaints: text and details can drift
Best for	Upscaling product shots, lettered posters, design assets	"Repaint it sharper" cases

Same source image, both approaches, real outputs

Pair A: watch product shot (640×640 source)

Original 640×640	Crisp 2× $0.004	Seedream 2K repaint $0.035

Middle: recraft/crisp-upscale, 640×640 → 1280×1280, $0.004, dial text untouched. Right: seedream-5.0-lite/image-to-image, 2K repaint, $0.035, prompt "Same image, preserved composition and colors"; pixel sizes differ between the two.

The Seedream prompt (deliberately "keep it the same"):

Same image, preserved composition and colors, sharp fine detail, no artifacts

What you can see in pair A:

• Crisp enlarges the dial, steel, and the AUTOMATIC small print as-is — not a letter moved.
• Seedream repaints the dial detail even with a "keep it the same" prompt — close to the original but not the original; small-type letterforms can differ slightly on close inspection.

Pair B: lettered poster (427×640 source)

Original 427×640	Crisp 2× $0.004	Seedream 2K repaint $0.035

Middle: recraft/crisp-upscale, 427×640 → 854×1280, $0.004. Right: seedream-5.0-lite/image-to-image, 2K repaint, $0.035 (same prompt).

What you can see in pair B:

• Crisp keeps the headline letterforms and layout exactly, just clearer.
• Seedream's repainted headline is close but not identical — the delivery risk for lettered assets.

Choosing by scenario

• Product shots, lettered posters, finalized design assets: Crisp Upscale — $0.004 for faithful 2× with zero drift.
• Photo restoration, "repaint it finer" cases where detail may change: Seedream 2K.
• The budget gap compounds: 1,000 images cost $4.00 on Crisp versus $35.00 on Seedream.
• They chain well: Crisp first to hold the subject, then Seedream locally where repainting helps.
• Background on generative upscaling approaches: the resolution tutorial.

Switching cost: very different bodies

Mind the field names: Crisp takes image_url (a string); Seedream takes image_urls (an array) and requires a prompt.

FAQ

Does Crisp change the content?

No. Text, composition, and color stay as-is — the fundamental difference from repaint models.

Does Seedream repaint even with a "keep it the same" prompt?

Yes. High similarity, not pixel identity.

Are the output pixels the same?

No. Crisp doubles; Seedream outputs by resolution tier (2K / 4K same price; 2K default) — captions state it.

How big is the 1,000-image gap?

$4.00 versus $35.00 — nearly 9×.

Can I use both together?

Yes. A common chain: Crisp upscales everything to stay usable, and Seedream repaints only the few frames that need retouching.

Next: take one of your product shots and upscale it on the Crisp page ($0.004) to see the fidelity; try Seedream when you want repainted detail. Crisp usage is in the API guide; five original pairs are in the examples page.
