Replicate NightmareAI is an upscaler profile, and this page does not call it
On the Replicate profile read on 2026-11-07, nightmareai/real-esrgan had about 103.2 million runs. The next models were far smaller. That model is Real-ESRGAN with optional face enhancement, not a text-to-image product. This form does not use it.
This generator runs Nano Banana 2.1 for 8 credits at 1K. It is not a Replicate account, it does not call NightmareAI, and it does not upscale 2x, 4x, or 10x.

Real-ESRGAN files, not this form
The coast and the building were cropped on 2026-11-07 from the teaser in xinntao/Real-ESRGAN. Anime, brand signs, and arrow graphics in that teaser were left out. The wordmark is their logo. None of these is a Nano AI upscale.
What Replicate NightmareAI refers to
The public profile at replicate.com/nightmareai, read on 2026-11-07, lists several models. Run counts that day were about 103.2 million for real-esrgan, 116.8 thousand for latent-sr, 72.7 thousand for latent-viz, 64.9 thousand for disco-diffusion, 32.9 thousand for cogvideo, 16.1 thousand for arf-svox2, 8.3 thousand for majesty-diffusion, and 7.4 thousand for k-diffusion. Real-ESRGAN is the model people hit. latent-sr is also an upscaler. disco-diffusion, k-diffusion, and majesty-diffusion are older image generators, and cogvideo is text to video. They are not what the run count says this search is about, and this site does not call any of them.
The real-esrgan readme on Replicate says it is the latest Real-ESRGAN with GFPGAN and an outscale option, and that the maximum recommended input is 1440p. Version pages read the same day both take an image, a scale, and face_enhance. One version lists scale default 4 and maximum 10, with face_enhance default false. Another lists face_enhance default true. This page does not pick a winner between those defaults. The upstream project is xinntao/Real-ESRGAN, BSD 3-Clause, copyright 2021 Xintao Wang. The repository describes practical restoration trained on synthetic data, with optional GFPGAN face enhancement, and names weights such as realesrgan-x4plus, realesrnet-x4plus, realesrgan-x4plus-anime, and realesr-animevideov3. The Replicate readme does not list every weight file. This site has not downloaded those weights.
A new picture is not an upscale. Nano Banana 2.1 costs 8 credits at 1K, with up to 5 reference images. A reference image is an input to a new picture. The output is still 1K. It does not multiply width and height, does not run GFPGAN, and does not send a scale of 4 or 10. /image-resizer changes pixel dimensions for social frames. It is not Real-ESRGAN. /krea-ai-enhancer-free and /magnific-spaces already say this site does not upscale 2x, 4x, or 8x. Eligible new accounts receive 64 credits, which is 8 images on Nano Banana 2.1. Those credits are not Replicate credit.

How to read a Replicate NightmareAI result
The run count is an upscaler
About 103.2 million runs were on real-esrgan. latent-sr, the other upscaler, was about 116.8 thousand. Image generators on the same profile were smaller still.
Two version pages disagree on the face default
One lists face_enhance default false and the other true. Both list scale default 4 and maximum 10. This page quotes both instead of merging them.
This button is a new 1K image
Nano Banana 2.1 is 8 credits at 1K. It does not upscale. /image-resizer only changes dimensions. It is not Real-ESRGAN.
The samples are theirs
The coast and the building are crops from the upstream teaser. The wordmark is their logo. None of them is a file this form enhanced.

How to make a still on this page
- 1
Start from a prompt, not an upscale factor
Pick one of the four prompts. None of them asks for 2x, 4x, or 10x. Change the subject so the picture is yours.
- 2
Leave Nano Banana 2.1 selected
The menu opens on Nano Banana 2.1 at 8 credits and 1K. A reference image, if you add one, is an input to a new picture. It is not passed to Real-ESRGAN.
- 3
Treat the gallery as theirs
The coast, the building, and the wordmark are upstream files. They show what Real-ESRGAN published. They are not before-and-after pairs made by this button.

FAQ
Replicate NightmareAI questions
Answers use the profile, the real-esrgan pages, and the upstream repository as read on 2026-11-07.
Will this button upscale my photo 4x?
No. It runs Nano Banana 2.1 for 8 credits at 1K. It does not call nightmareai/real-esrgan and does not apply a scale of 4 or 10.
Does Nano AI include a Replicate account?
No. Sign-up credits here are Nano AI credits. They are not Replicate credit, and this page does not create a Replicate login.
Is NightmareAI only an upscaler?
The profile also lists latent-sr, latent-viz, disco-diffusion, cogvideo, arf-svox2, majesty-diffusion, and k-diffusion. The run count on 2026-11-07 was dominated by real-esrgan. This page does not call the smaller models either.
Why do the face defaults disagree?
Two public version pages were open on 2026-11-07. One set face_enhance default to false and the other to true. Both are quoted. This site has not run either version.
Can I resize without pretending it is Real-ESRGAN?
Yes. /image-resizer changes pixel dimensions for a social frame. It does not run GFPGAN or a learned upscaler. The picture from this form is a new 1K image, not a resized upload.
Is Nano AI affiliated with NightmareAI or Replicate?
No. The samples and the run counts are theirs. The generator on this page is Nano Banana 2.1.
