Last month, Google's image generation model Nano Banana burst onto the scene, able to follow complex instructions, maintain consistency, and preserve contextual details. Many people exclaimed that this thing completed theAI paintinglast piece of the puzzle—Gemini is truly invincible...
But friends who have played with it for a while also know that this thing has a hard flaw—its Chinese comprehension ability is average, and it still renders Chinese text with all kinds of garbled characters...
Yesterday, ByteDance officially launched Seedream4.0, where a single model achieves text-to-image, multi-image reference, and group image generation, going head-to-head with Nano Banana.
Especially in Chinese semantic understanding, it completely beats Google's Nano Banana model.The Most Complete Collection of Nano Banana Gameplay on the Internet(with 4 free ways to get it for nothing)
After playing with it for a day, I sorted out the 10 most typical and practical ways to use it. Let's take a look together next.
01. How to Use Seedream 4.0
For this review, K-jie mainly used Jimeng. In image generation mode, select the Image 4.0 model.
Official website:https://jimeng.jianying.com
What is used here is the Seedream 4.0 model.
In Jimeng's intelligent reference function, you can select an editing area, enabling very precise local modifications.
02. Master Pixel-Level Editing
One-Click Figure Generation
One of Nano Banana's most popular use cases is one-click figure generation. Let's take a look at how Seedream4.0 performs in this area.
Upload a photo and enter the following prompt:
Prompt: Draw the character in the image as a 1/7 scale commercial figure, realistic style, real environment. The figure is placed on a computer desk, on a circular transparent acrylic base. The content on the computer screen is the C4D modeling process of the figure, and next to the computer screen is placed a plastic toy packaging box printed with the original art in theBANDAIstyle, ensuring all elements remain consistent with the reference image.
The generated figure image is very realistic. Details such as the character's pose, facial features, expression, clothing, and shooting angle are consistent with the original image.
K-jie has tried it—realistic, anime, and various styles can all be done~ You can even arrange it for pets too.
Model Try-On
Using the same model as above, we can generate try-on effects for various outfits with a single sentence.
Prompt: Put the outfit from image 2 (below) on the girl in image 1
In the same way, you can have her continue to put on shoes, bags, and accessories.
Prompt:
For making multiple modifications in a single pass, Seedream4.0's performance is also excellent, with most consistency of the person and product maintained very well.
The details of the bag and bracelet, even the buckle decorations on the shoes, were restored. However, the recognition of the glasses is still not very accurate.
We can also have the model pose for photos by referencing various poses.
Prompt: The person in image 1 poses for a photo by referring to the pose in image 2.
Pose reference image:
Generated effect:
One model, any product, displayed in various poses... Isn't this a free AI model? It saves both time and money.
After testing it herself, K-jie found that,the effect is better when the model and the pose reference image are in the same shot size; for example, I used a full-body photo of the model, and the reference pose was also a full-body photo, and the effect was very good. When the reference pose is a half-body photo, Seedream4.0 will fill in the lower-body movements on its own.
Makeup Imitation
Prompt: Apply the makeup from Image 2 to the girl in Image 1, without changing the person's facial features.
After replicating the makeup, the person's pose and facial features still look like the original image. The forehead flower ornament is painted almost exactly like the reference image, and the overall replication is quite good~ However, the eyeshadow color is a bit too heavy.
Nine-grid emoji pack
Prompt: Referring to the image character, generate an emoji pack containing various emotions. No eye expressions; the eye areas are replaced by the minimalist lines of AR glasses.
Prompt: Referring to the image, generate cute emojis in an anime style with exaggerated dynamics and full of cuteness. Each expression is lifelike, vividly conveying rich emotions, highly collectible, with a consistent overall style.
Brand design
Prompt: Referring to this LOGO, create a set of healing-style plush toy brand visual design, with the brand name "Kjie", including packaging bags, paper boxes, cards, wristbands, lanyards, etc. Yellow as the main visual color tone, cute aesthetics.
Multi-angle product images
Prompt: Generatethree-view。
One-click generation of multi-scene real-shot images
Prompt: Generate multi-scene real shots, such as: sofa, display cabinet
Replicate poster style
Prompt: Referring to this style, make a poster for the Start of Spring.
Seedream4.0 replaced the title and the text content in the poster, and also changed the ginkgo leaves in the background to willow branches that fit spring. The semantic understanding is very strong.
Renovation
Prompt: Renovate Image 1 referring to the style of Image 2.
Seedream4.0 has a strong understanding of space. In the generated renovation renderings, the positions of windows and walls, as well as the perspective, are completely consistent with the original image. Any nice interior design image can be directly applied to your own home to see if it fits, which is very worry-free~
Comic strip
Prompt: Referring to the image characters, generate 20 comics respectively, for example: 1. A boy and a girl sitting in the living room chatting 2. The boy cooking in the kitchen while the girl keeps him company 3. The boy and the girl shopping
Jimeng can also generate multiple images in a single run. For example, when we enter a requirement for >4 generated images in the prompt, Jimeng will first generate 4 and ask below the images whether to continue generating the remaining images.
However, a single run can generate at most 13 images. We click to continue generating.
03. Some sharing
Overall, after using it, Seedream 4.0's generation quality is quite high, and its style control ability is also very good. Even slightly more complex scenes are no problem to use, except that sometimes local details still have minor flaws.
But I think that for designers and content creators, it is already in a usable state, and making posters and such is very convenient.
Seedream 4.0 is positioned as a one-stop image creation model from generation to editing. It integrates text-to-image (T2I) and image editing (SeedEdit) into a unified DiT architecture, and adopts joint training in the SFT and RLHF stages, significantly improving instruction following and aesthetic performance.
By introducing a fine-tuned version of SeedVLM, the model is endowed with world knowledge and contextual understanding capabilities, making the model stronger in logical reasoning, physical constraints, and common-sense judgment.
This series of operations successfully pushed image generation toward productization. AI image content generation is no longer synonymous with low quality and low efficiency.
