[No Payment Required] Introducing "Flow," a site where you can use Nano Banana Pro for free! We also verify the daily usage limit!

Hello! I am Tanabe.

Nano Banana Pro is becoming an essential piece of infrastructure.
However, since it is basically only available for a fee, many people have likely given up on using it.
You can use Nano Banana Pro for free on a site called "Flow"!

Flow is a secure site operated by Google.
All you need to use it is a Google account.
There is no need to pay or register a credit card.
Although there is a daily generation limit, you can truly use Nano Banana Pro for free.

With this,

• educational institutions such as schools

• public institutions

and others may find it easier to use for work purposes.

In this article, I will introduce how to use Nano Banana Pro from Flow and the daily usage limit.
Please take this opportunity to use Nano Banana Pro!

What can you do with the Flow version of Nano Banana Pro? Explaining the features

First, I will introduce what features are available when using Nano Banana Pro from Flow.
Let's check what you can do!

1. The image generation AIs you can choose from in Flow are "Nano Banana Pro" and "Nano Banana 2"

I mentioned that "you can use Nano Banana Pro for free on Flow,"
but actually, you can also use "Nano Banana 2," which can be called a low-cost version, for free.

Both models allow you to create up to 4 images at once per generation,
making it possible to efficiently generate a large number of images in a short time.

2. You can choose from 5 aspect ratios (portrait orientation is also supported)

You can choose from the following 5 aspect ratios for the images you generate.

• 16:9

• 4:3

• 1:1

• 3:4

• 9:16

Generally, it is safe to choose "16:9" when creating landscape images and "9:16" when you want to create portrait images.
By using them according to your purpose, you can create more appropriate images.

3. Images can be downloaded without watermarks

Images generated with Flow do not have watermarks.
Here is an image I actually generated and downloaded using Flow ↓

For free AI services, images and videos often come with watermarks, so this is a welcome feature.

4. You can upscale to 2K even for free

When you generate an image using Nano Banana Pro on Flow, the initial resolution is 1K.
However, you can upscale (increase the resolution) when downloading.

Images can be upscaled up to 4K, but 4K support is only for paid members.
Free members can upscale up to 2K.
Even so, you can still use high-quality images.
The fact that this is supported for free is a very attractive point.

Verifying the daily generation limits for Nano Banana Pro and Nano Banana 2

Next, I will introduce the "daily generation limit" that everyone is curious about.

That said, there is no official announcement from Flow.
Therefore, I verified it by generating images myself.
*Verification period: April 8th to April 9th, 2026
In conclusion, the daily limits are as follows.

1. Nano Banana Pro: About 10 to 20 images

2. Nano Banana 2: 100+ images

In the case of Nano Banana Pro, the following message appears when you reach the limit.

At the time I verified it, once this message appeared, I was unable to generate images for about 24 hours.
Therefore, if you reach the limit, you need to wait for one day.

However, even if you reach the generation limit for Nano Banana Pro, you can still continue to use Nano Banana 2.
This is because the limits for Nano Banana Pro and Nano Banana 2 are managed separately.

Nano Banana 2 is considered a "low-cost version of Nano Banana Pro," but its performance is very high and it is quite practical.
Since you can generate a large number of images, it is especially recommended for those who want to generate images without worrying about limits.

Explaining how to use Nano Banana Pro from Flow

From here on, I will explain how to use Nano Banana Pro from Flow by dividing it into the following three types.

• How to generate images from text

• How to generate images by referencing an image

• How to upscale to 2K and download

① How to generate images from text

First, access Flow and log in with your Google account.

・Flow official website URL
https://labs.google/fx/ja/tools/flow

Once logged in, click the center of the screen (refer to the image below).

Select Nano Banana Pro on the next screen and you are ready to go.
Please refer to the image below for this as well.
Just configure the settings in the order of the numbers.
※ Please change item ③ according to the size of the image you want to create.
※ If you want to use "Nano Banana 2," please change ①.

After that, just enter your prompt and press the generate button.
Flow has a fast generation speed for Nano Banana Pro, so generation is generally completed in a few dozen seconds.

② How to generate images by referencing an image

Next, I will explain how to generate a new image by referencing a specific image.

• I want to partially modify an image

• I want to generate a different scene using a character from an image

This is a technique often used in situations like these.

First, I will introduce how to upload and reference image data from your computer.
That said, the operation is very simple; just follow the steps in the order of the numbers in the image below.

Once uploaded, that image will be in a referenced state.
In that state, enter your prompt and generate the image.

When you want to reference an image generated within Flow, click on that image.
When you click it, the screen will change as shown below.

Enter your prompt in the red frame area of the image above and press the generate button to create the image.
By doing so, an image reflecting the instructions in your prompt will be generated.

③ How to upscale an image to 2K and download it

Finally, I will introduce how to upscale an image to 2K and download it.
You can download it by following the steps below.

1. Click the "︙ (three dots)" in the upper right of the image you want to download

2. Click "Download"

3. Click "2K"

With this, you can download images upscaled to 2K.

That concludes the explanation on how to use Nano Banana Pro for free via Flow.

While it is attractive to be able to use it for free, there has been no official announcement from Google regarding how long this offer will last.
Therefore, we recommend that those who are interested try it out as soon as possible.
