Nano Banana 2 on Grok Image now runs on Nano Banana 2.1, the newer and lower-cost model.

Build a design reference before committing to motion.

Set your options on the left, then start a generation.
Before you create
Keep the subject, composition and intended use in your brief. Use references you own or have permission to upload. Check the selected mode and its credit quote before submitting; changing resolution or video length can change the cost.
Does the free image offer apply?
The welcome offer covers one GPT Image 2.5 image at 1K. It does not cover every image model or a video generation. Plans and credits apply to Grok Image only.

What can you create with Nano Banana 2.1?
Create an image from a written brief, or edit with reference images. On Grok Image, start with a design composition or product reference. Keep your source material and intended result together in the generator above.
Prepare your inputs
A prompt and, in edit mode, up to 10 reference images. Use PNG, JPEG, or WebP; this uploader accepts up to 20 MB per file.
Describe the subject, framing, lighting, materials, and the changes to preserve. Avoid combining unrelated scenes in one image.
From brief to result
- Select the mode and describe your intended result in the generator on this page.
- Add references you own or have permission to use, then choose output settings.
- Review the exact credit quote before submitting. Availability and balance checks happen before a generation request.
- When a task completes, review the output before downloading it or starting another variation. A pending task is not a completed result.
Limits to check before generating
Choose 1K, 2K, or 4K and a supported aspect ratio. References guide the composition but do not guarantee exact typography or identity.
Do not submit confidential material without the necessary permission. An accepted upload does not guarantee a usable output. If a request fails, keep the task record and check its credit refund rather than repeatedly submitting the same input.
Credits and availability
The quote changes with resolution. The registration gift is reserved for GPT Image 2.5 at 1K, not this model.
A model marked unavailable cannot start a paid task. It is not a reason to buy credits until generation has been enabled. Plans, balances, and private history apply to Grok Image.
Can I change models without starting over?
Keep the brief, then review the new model's settings. Different models accept different references and durations, so check the required inputs and quote again before submitting.
Model details last checked on September 8, 2026. Upload limits on this website may be narrower than the model's own maximum.
Nano Banana 2.1 vs Nano Banana Pro
Choosing between Nano Banana 2.1 and Nano Banana Pro? Here is what Grok Image can actually offer. Nano Banana 2.1 is the Nano Banana model you can generate with on this page. Nano Banana Pro is retired here, so there is no Pro price or Pro result to compare side by side.
| On Grok Image | Nano Banana 2.1 | Nano Banana Pro |
|---|---|---|
| New generations | Available in the generator above | Retired; not accepted |
| Output size | 1K, 2K or 4K | Not offered |
| Reference images | Up to 10 in edit mode | Not offered |
| Credits per image | 3 credits at 1K, 5 at 2K, 8 at 4K | Not offered |
We do not rank speed, image quality or text rendering between the two: Nano Banana Pro is no longer run on this site, so any comparison would be unmeasured. References guide composition with Nano Banana 2.1 but do not guarantee exact typography, so check lettering in the result before you download.
Which model should you pick on Grok Image?
- Nano Banana 2.1: reference-led edits with up to 10 images, or when you want to choose 1K, 2K or 4K and see the price first. Start at 1K for 3 credits, then repeat at 4K for 8 credits once the composition works.
- Seedream 5.0 Pro: another Pro-tier image model for product and composition edits at 1K (7 credits) or 2K (14). It does not offer 4K.
- GPT Image 2.5: 3 credits at 1K, 10 at 2K and 16 at 4K. The welcome gift applies to this model at 1K.
- Grok Imagine Image 2.0: 4 credits per image, and your result can become the starting frame for a video.
Is Nano Banana 2.1 better than Nano Banana Pro?
On Grok Image the question is practical rather than a ranking: Nano Banana 2.1 is the Nano Banana model you can run here, and Nano Banana Pro is retired on this site. We have not published a speed, quality or text-rendering benchmark between the two, so test your own prompt and check the credit quote before you submit.
Can I still generate with Nano Banana Pro on Grok Image?
No. New Nano Banana Pro generations are not accepted here, and no credits are charged for it. Older Pro results stay readable in your history. For new work, use Nano Banana 2.1 on this page, or compare Seedream 5.0 Pro, GPT Image 2.5 or Grok Imagine Image 2.0.
