Topaz API pricing: $0.05 to $0.10 per image

According to APITariff, the Topaz API costs $0.05 to $0.10 per upscaled image across 4 routes on 2026-09-24, and the cheapest route depends on the output size. At 1,000 images a month, images up to 2K cost $50 through kie.ai against $80 on fal.ai, and 4K images cost $80 on fal.ai against $100 through kie.ai. Topaz Labs sells its own API in credits: 1 credit upscales one image up to 24 megapixels, at $0.10 on the $50-a-month Developer plan or $0.08 on the $240-a-month Scale plan. kie.ai, a reseller, charges $0.05 per image up to 2K and $0.10 per 4K image. fal.ai charges $0.08 per started 24 megapixels of output. Replicate’s page prints two prices for the same Topaz model: $0.08 per unit in its price box and $0.05 per unit in its size table. We compared the 4 pricing pages and computed the bill at 100, 1,000 and 3,000 images a month.

Topaz API pricing per image, side by side

kie.ai is the lowest listed price up to 2K, at $0.05, tied with Replicate’s size table. At 4K it costs $0.10, 25% more than fal.ai and the Topaz Scale plan at $0.08, and double Replicate’s table price of $0.05.

Route	Up to 2K	4K (8.3 MP)	Up to 24 MP	Fee
kie.ai Topaz Image Upscaler	$0.05	$0.10	no price row	prepaid credits
fal.ai Topaz Upscale Precision	$0.08	$0.08	$0.08	per request
Replicate topazlabs/image-upscale	$0.05 or $0.08	$0.05 or $0.08	$0.05 or $0.08	per unit
Topaz Labs, Scale plan	$0.08	$0.08	$0.08	$240 a month, 3,000 credits
Topaz Labs, Developer plan	$0.10	$0.10	$0.10	$50 a month, 500 credits
Topaz Labs, Starter plan	$0.12	$0.12	$0.12	$0 a month, “COMING SOON”

USD per upscaled image. Sources: topazlabs.com/api, kie.ai pricing API and kie.ai/topaz-image-upscale, fal.ai and Replicate model pages, all read 2026-09-24. 4K means 3,840 by 2,160 pixels, 8.3 megapixels, which is one credit or one unit on every route that bills by megapixels. Replicate: $0.08 is the price box our daily fetch reads, $0.05 is the size table on the same page; the section on Replicate below explains the gap.

Cost at three volumes

At 100 images a month the Topaz Developer plan works out to $0.50 per image, because the $50 fee buys 500 credits whether you use them or not. At 3,000 images a month the Scale plan and fal.ai tie at $240.

Images a month	kie.ai	fal.ai	Replicate	Topaz Developer	Topaz Scale
100 at 4K	$10	$8	$5 or $8	$50	$240
1,000 at 4K	$100	$80	$50 or $80	$100	$240
3,000 at 4K	$300	$240	$150 or $240	$300	$240
1,000 up to 2K	$50	$80	$50 or $80	$100	$240

Computed 2026-09-24 from the per-image prices above. Topaz Developer beyond 500 credits assumes the auto-reload Topaz describes, “at the current per-credit price”, $0.10.

Where kie.ai loses

Four cases favour another route on the prices read 2026-09-24.

1. At 4K, kie.ai’s $0.10 is 25% above fal.ai and the Topaz Scale plan at $0.08, and double Replicate’s table price of $0.05.
2. Above 4K, kie.ai’s pricing API has no price row. Its model page mentions ”~$0.18 per 8K image” after a top-up bonus, and Topaz direct bills 2 credits for a 32 MP output.
3. For video, fal.ai bills $0.01 per second at 720p and $0.02 at 1080p, against $0.04 per second on kie.ai at 1x or 2x. A 60-second clip costs $1.20 on fal.ai at 1080p and $2.40 on kie.ai at 1x or 2x, whose output resolution kie.ai does not state.
4. kie.ai does not say what “2K” measures, and does not name the Topaz enhance model it runs. fal.ai and Replicate both list Standard V2, High Fidelity, Low Resolution, CGI and Text Refine.

Where kie.ai wins

Up to 2K output, kie.ai’s Topaz Image Upscaler costs $0.05 per image on its pricing API, read 2026-09-24. That is 50% under the $0.10 Topaz Developer plan rate and 37.5% under the $0.08 charged by fal.ai and the Topaz Scale plan, and it ties the $0.05 in Replicate’s size table. kie.ai bills from prepaid credits with no monthly plan, so 100 small images cost $5 on kie.ai, against the $50 a month the Topaz Developer plan charges before the first image. At 1,000 small images a month the gap is $50 on kie.ai against $80 on fal.ai and $100 on the Topaz Developer plan. The kie.ai pricing comparison shows the same reseller discount on 31 text models.

How much does the Topaz Labs API cost?

Topaz Labs lists 3 API plans on topazlabs.com/api, read 2026-09-24: Developer at $50 a month for 500 credits ($0.10 each), Scale at $240 a month for 3,000 credits ($0.08 each), and Starter at $0 a month with credits at $0.12, marked “COMING SOON”.

According to the Topaz Labs API page, one credit covers one Enhance request up to 24 megapixels of output, such as 6,000 by 4,000 pixels. Larger outputs cost more: 2 credits at 32 MP, 3 at 48 MP and 16 at 512 MP. Enterprise pricing is by contact. Topaz takes monthly card payments through Stripe.

Do Topaz API credits expire?

No. Topaz Labs states on its API page, read 2026-09-24: “All unused credits roll over each month and never expire.” The balance is capped at 5 times the monthly credit volume, so the Scale plan’s 3,000 credits a month allow a balance of 15,000 while the plan stays active. When credits run out, Topaz reloads 25% of the plan “at the current per-credit price” to avoid an interruption, which on the Developer plan is 125 credits at $0.10.

What does Topaz video upscaling cost through an API?

Topaz Labs’ API page, read 2026-09-24, prints no per-second video price. fal.ai bills Topaz video precision models at $0.10 per 10 seconds of output at 720p, $0.20 at 1080p and $0.60 at 4K, which is $0.01, $0.02 and $0.06 per second. kie.ai bills $0.04 per second at 1x or 2x upscale and $0.07 per second at 4x, and does not state an output resolution. On those listed rates a 60-second clip costs $1.20 on fal.ai at 1080p and $2.40 on kie.ai at 2x. The fal.ai Topaz video record tracks the fal.ai rate daily.

Why does Replicate show two Topaz prices?

Replicate’s Topaz image-upscale page, read 2026-09-24, carries a price box that says “$0.08” “per unit”, “or around 12 units for $1”, and a table further down that prices 1 unit, up to 24 megapixels, at $0.05 and 17 units, up to 512 megapixels, at $0.82. Our daily fetch reads the price box, so the Replicate model record shows $0.08. We have not run a Replicate request to see which figure the invoice uses, so this page prints both.

The rule we apply

For each output size, the lowest listed price per image on 2026-09-24 wins, and a monthly plan fee counts toward the per-image cost at the stated volume. The rule compares price only. We ran no upscale request on any of the 4 routes, so output quality, speed and the Topaz model each reseller runs are not compared. The methodology page lists how every price on APITariff is fetched, and the per-budget picks apply the same kind of printed rule to every model. The same three hosts are compared for video generation in the Seedance API pricing comparison.
