On 8frame, two image models have a 4K setting: Nano Banana 2 (22 credits per image at 4K) and Nano Banana Pro (42 at 4K). Seedream 5 Lite goes to 3K at its flat 6 credits. Seedream 5 Pro, Qwen Image 3 and Grok Image stop at 2K. The rest, including Imagen 4, Midjourney and FLUX, have no resolution setting on 8frame. If you need a large file from one of those, an upscaler is usually the cheaper route: BRIA enlarges 2x or 4x for 6 credits, up to 8192 x 8192. All of this is read from the 8frame app on 2026-09-29.
Resolution settings and prices
| Model | Resolution options | Credits per image |
|---|---|---|
| Nano Banana 2 (default Nano Banana) | 0.5K, 1K, 2K, 4K | 8, 11, 17, 22 |
| Nano Banana Pro | 1K, 2K, 4K | 21, 21, 42 |
| Seedream 5 Lite | 2K, 3K | 6 at either |
| Seedream 5 Pro | 1K, 2K | 7, 13 |
| Qwen Image 3 | 1K, 2K | 6, 11 |
| Grok Image 2.0 | 1K, 2K | 9, 11 (default quality) |
| GPT Image 1.5 | Fixed sizes: 1024 x 1024, 1536 x 1024, 1024 x 1536 | 18 to 26 at high quality |
| FLUX.2 [pro] | About one megapixel presets | 5 |
| Nano Banana Standard, Seedream 4, Imagen 4, Midjourney, GPT Image 2 | No resolution setting on 8frame | See price per image |
"1K", "2K" and "4K" are the model's own labels for its output size class; the exact pixel dimensions depend on the aspect ratio you choose.
When 4K is worth paying for
- Print. A poster or a large print needs pixels that screens don't. Generate at 4K, or generate smaller and upscale.
- Heavy crops. If you'll crop a detail out of the frame, start big.
- Readable fine text. Nano Banana Pro at 4K (42) gives small lettering more pixels to land on.
For social posts, thumbnails and slides, 1K or 2K is enough, and on Nano Banana 2 it's half the price of 4K.
Generate at 4K, or upscale?
| Route | Cost | Good for |
|---|---|---|
| Nano Banana 2 at 4K | 22 | New details at full size, one step |
| Nano Banana 2 at 1K + BRIA 4x | 11 + 6 = 17 | Enlarging an image you already like, content-preserving |
| Seedream 5 Lite at 3K | 6 | The cheapest large native output |
| Any model + Clarity upscale | +13 | Enlargement that adds detail |
| Any model + Topaz | +11 per 24-megapixel block of output | Very large print files |
BRIA is built to preserve content rather than invent it, which is what you want when the image is already right. Clarity and Topaz can add or change detail, so check faces and lettering at 100% after them. More in best AI upscaler.
File format and size
Every image model we measured on 8frame returns a PNG, and 8frame keeps that file as it is: the Original download is the model's PNG. The download menu also offers smaller WebP copies, 256, 640 and 1280 pixels wide, when they exist. Measured medians over the 120 days to 2026-09-30:
| Model | Median image | Median file |
|---|---|---|
| Nano Banana 2 | 4.2 megapixels | 5.5 MB |
| Nano Banana Pro | 4.2 megapixels | 6.0 MB |
| Seedream 5 Pro | 4.0 megapixels | 6.9 MB |
| Seedream 5 Lite | 9.4 megapixels | 7.1 MB |
A 4-megapixel PNG is about 5 to 7 MB. Check a platform's upload limit before sending originals, and use a WebP copy when a smaller file is enough.
FAQ
Which AI image generator makes 4K images? On 8frame, Nano Banana 2 (22 credits at 4K) and Nano Banana Pro (42 at 4K). Seedream 5 Lite goes to 3K for 6 credits.
How much does a 4K AI image cost? 22 credits on Nano Banana 2 or 42 on Nano Banana Pro, $0.22 or $0.42 at pack rate. A 1K image plus a 4x BRIA upscale costs 17.
Why doesn't Midjourney have a resolution option on 8frame? Midjourney, Imagen 4 and some others run at the model's own output size on 8frame, with no resolution setting. Use an upscaler if you need more pixels.
Is it better to generate at 4K or upscale? Generate at 4K when you want the model to draw fine detail at full size. Upscale with BRIA when you already have the image you want and need it bigger without changes.
