About SAI's technology

RADIUS5 has developed an AI technology called RefineGAN that generates an infinite number of illustrations, making it easy for users to generate images in line with their preferences through a simple UI operation.
So far, the use of image generation AI has been confined mostly to the realm of academic research. Through our real-world application of this experimental technology, we have succeeded in implementing and introducing a highly useable AI service to broader society.
SAI's technology, which is based on RefineGAN, is able to produce professional-level images and refine existing illustrations.

Our vision

Generative models have evolved dramatically in recent years, including Generative Adversarial Networks (GAN), Variational Auto-Encoders (VAE), and style transfer, but they have not as of yet been widely incorporated into tools used in practice by real-world visual arts professionals such as designers and graphic artists.
RefineGAN can recursively generate images through interaction with the user through a simple UI.

SAI's learning process

SAI, just like a human illustrator, learns through looking at images, capturing elements such as eyes, hair, and other features of illustrations.
As a result, SAI can produce entirely new illustrations, not a combination of parts.

Output

RefineGAN can generate an unlimited number of images. It can also generate a gradation of intermediate images between any two starting images, or images with similar characteristics to another image.

Features

*Produces professional-quality images in large quantities
*Based on simple user input, it is possible to output images recursively and generate images closer and closer to the user's ideal image.
*User input similarity can be calculated and the following output can be controlled dynamically and in a stable manner
*Users can receive low-latency generated images based on their input

*This technology is patented.

Usage Examples

Original icon for your SNS

SAI can provide you with original character icons different from what anyone else has.
Use the original icons generated by SAI on SNS such as Instagram, Twitter, Facebook, LINE, etc.
More than 1 million types of icon can be generated, so ask SAI to draw characters that express your personality.

Advertising and flyers

SAI's illustrations are generated as 512 x 512 px images, and can be used in various advertising materials such as banners or flyers. If the image resolution is not enough, you can use the Photo Refiner service to increase the resolution before using it.

Image characters for a company or service

If you are used to ordering expensive character designs and illustrations from design companies, then waiting a long time for the results, SAI can take care of your character design needs for a fraction of the time and the price.
Please contact us if you are interested in exclusive usage of a character design generated by SAI

As a reference for character design production.

Cartoonists and illustrators envision and create numerous character designs every day. SAI can help reduce the effort required to come up with ideas for character creation.
Each time you select a character you like, SAI suggests several character designs similar to the one you selected. Let SAI provide you with inspiration for new characters!

Game and independent production materials

Say you want to produce a game or a self-made project - but do not have the time, money, or resources to draw your own characters, or to outsource the production.
SAI can help you solve all these problems! Together with SAI, we as RADIUS5 strive to provide our services a partner in game productions for various agencies and individuals.

We provide an API to SAI for use in various systems.

Q&A

Q.What do you mean SAI draws illustrations?

A.SAI is an AI which has been trained on the characteristic features of facial illustrations. Like a human designer, SAI learns by looking at various illustrations before it can draw them. For example, SAI learns the parts that make up character illustrations, such as two eyes, one mouth, eyebrows over the eyes, etc.
SAI does not store the learned illustration data. It does not just produce a combination of parts from other images. SAI learns the essence of what face illustrations are, and as a result, learns to produce illustrations on its own.

Q.How can I get an illustration drawn by SAI?

A.SAI will draw an illustration similar to the image you selected, as well as several new illustrations. The resulting illustrations are then lined up with the ones closest to the selected illustration near the center.
As you continue to choose images, SAI refines its illustrations to produce something closer and closer to what you want.
However, because SAI is an artist by nature, it won't always predict your needs perfectly - and incorporates its expression into its work.
SAI is a little whimsical, so feel free try it out and let it produce your new favorite illustration.

Q.Are there any restrictions on the use of the images drawn by SAI?

A.The illustrations drawn by SAI can be used as materials for commercial use. Images made by SAI can be downloaded as PNGs, and may be edited, processed, or incorporated into other materials freely. However, it is prohibited to sell the downloaded images to third parties.

Q.Please tell me about the usage fees.

A.There are two options for payment.
(1) Entry Plan
Illustrations can be purchased on per-image basis (US $2.50/image) without a subscription and with no monthly subscription fee, payable by credit card.
(2) Light Plan or higher
If you are subscribed to the Light Plan or above, you can download one unwatermarked image for a cost of 5 credits (a point system available within cre8tiveAI). The higher the subscription plan, the more you save per image. For more details about the subscription plans and fees, please see
