Send a batch of images or audio. It waits its turn for a GPU, then every unit costs the fare in the table. That is cheaper than running the same jobs one at a time, because the whole batch shares one minimum and one cold start.
1,000 Real-ESRGAN images: $1.00 here, $2.00 on Replicate (checked 2 Nov 2026). One image alone costs more here, because of the $0.0075 minimum per submission.
| Service | Unit | List fare | Launch fare | Minimum, per submission |
|---|---|---|---|---|
| Real-ESRGAN x4plus Image upscaling, 4x | image per image up to 1 MP input, pro rata above that, up to 2 MP | $0.0010 | $0.0010 from 20 images | $0.0075 |
| Whisper large-v3 Speech to text | audio minute per minute of audio, by the second, 30 second minimum per file, up to 240 minutes | $0.00044 | $0.0004 from 30 audio minutes | $0.0075 |
| BiRefNet general Background removal | image per image up to 1 MP input, pro rata above that, up to 4 MP | $0.0005 | $0.0005 from 20 images | $0.0075 |
A submission pays the fare for its units or the $0.0075 minimum, whichever is more. On Whisper large-v3: A file under 30 seconds bills as 30 seconds. The launch fare needs a launch seat and at least the size shown in units that succeed. Failed and cancelled items don't count towards it.
Cheaper if you can wait. The name means what it means on a train ticket: you give up the fast connection and pay less for it.
Expect 10 to 30 seconds before your first result, occasionally minutes. GPUs start from cold when work arrives, and later items in a batch ride on the same start. If you need one answer right now, this is the wrong service.
Up to 100 files a call, straight to storage. Upload links last 1 hour.
See what the batch would hold and which files are missing. Nothing is written.
Up to 2,000 items. We hold the most it could cost, at the list fare.
Items run in turn, shared across accounts. Expect 10 to 30 s of cold start, occasionally minutes.
You pay for units that succeeded. Failed and cancelled items cost nothing, and the rest of the hold comes back.
Outputs stay for 7 days. Ask for links a page at a time.
The $0.0075 minimum applies per submission. Real-ESRGAN passes it at 8 images, so a batch of any real size pays only the fare. A thousand lone jobs pay the minimum a thousand times.
| The job | One batch, list fare | One batch, launch fare | One submission per job |
|---|---|---|---|
| One image, upscaled | $0.0075 | below 20 images | $0.0075 |
| 20 images, upscaled | $0.02 | $0.02 | $0.15 |
| 1,000 images, upscaled | $1.00 | $1.00 | $7.50 |
| 1,000 images, background removed | $0.50 | $0.50 | $7.50 |
| 1,000 one-minute clips, transcribed | $0.44 | $0.40 | $7.50 |
| 1,000 ten-second clips, transcribed | $0.22 | $0.20 | $7.50 |
Batching saves the most on small jobs. An audio file of 18 audio minutes or more clears the minimum on its own, so it pays the same list fare alone or in a batch. A file under 30 seconds bills as 30 seconds.

The launch fare is a lower rate on money you've already paid for, so the pack adds $25 of prepaid usage balance and no more. If the seats run out before your payment lands, you keep the whole pack at list fares.

I don't suppose they had ever thought about railways except as a means of getting to Maskelyne and Cook's, the Pantomime, Zoological Gardens, and Madame Tussauds. They were just ordinary suburban children, and they lived with their father and mother in an ordinary, red-brick-fronted villa, with coloured glass in the front door, a tiled passage that was called a hall, a bathroom room with hot and cold water electric bells french windows and a good deal of white paint and
