Released in February 2025, Seedream 5.0 Lite is ByteDance's best AI image generation model. You can use it on Overchat AI to create stunning images, and here are some reasons why you might prefer it to GPT Image 1.5 or Nano Banana Pro, which are also both available on the platform.
Seedream 5.0 Lite is the first image generation model in the ByteDance range that can search the web in real time — built on top of the excellent Seedream 4.5 foundation and now on a par with the best image generators from Google and OpenAI.

Compared to Seedream 4.5, version 5 adds:
Real-time web search
Better image editing
Spatial reasoning
Domain expertise
The model has made significant progress in terms of overall image fidelity, producing beautiful, photorealistic images across a wide range of subjects. In terms of image editing, it supports up to 14 reference images — one of the largest numbers in 2026 — allowing you to construct new scenes from a variety of elements.
Thanks to its ability to follow prompts and stick to instructions, the model can interpret references in many ways:
Include the attached images in the final generation
Remix them
Take style and lighting cues from them
Even when working with 14 images simultaneously, the model doesn't get confused.
What You Can Do With Seedream 5
Seedream 5 introduces three features that allow it to catch up to the best competitors in the form of Nano Banana Pro and GPT Image 1.5:
Live Knowledge
The model can access the web when generating images, meaning that the images it creates can reflect current events and include real people and events. The model decides when to search based on your prompt. Time-sensitive terms, specific entities and niche topics will automatically trigger an online search for accuracy.
What does this unlock? Here are a few ideas:
Create a visual about a breaking news story — it pulls real context.
Images of specific brands or products
Images around news that are happening right now (for example, real-time results of football matches)
Advanced Image Editing
Seedream 5 introduces a powerful new editing method: learning by example. This means that you can show it an example of the 'before' and 'after', then give it a new image and it will apply the same transformation to your photo automatically. In other words, Seedream 5 provides an easy way to apply style transformations or replicate edits from other images on your own photos.
Domain Expertise
The creators of this image generation model, ByteDance, have packed it full of specialised knowledge in different domains, including architecture, history, biology, chemistry and physics. This enables the model to produce accurate infographics, visualisations and diagrams on these subjects, addressing one of the major limitations of AI image generation: real-world accuracy, particularly on complex, knowledge-dense topics like these.
Spatial Reasoning
Seedream 5 understands how light and objects interact with each other, keeping track of this even through multiple generations. While you won't see this process live, as it takes place internally within the model, it occurs with every generation and leads to scenes that look more natural, without the uncanny valley effect, and that feel completely real and believable.
Character Consistency
It has always been difficult for AI image generators to preserve identity across different generations. Seedream 5.0 Lite makes big improvements here. Facial features, skin tone, clothing, and styling details look the same in different poses, angles, lighting conditions, and art styles.

Frequently Asked Questions (FAQ)
What is Seedream 5.0 Lite?
Seedream 5.0 Lite is ByteDance's latest AI image generation model. It builds on Seedream 4.5 and adds real-time web search, example-based editing, and multi-step logical reasoning. It generates and edits images from text prompts, reference images, or both.
Seedream 5.0 Lite vs Seedream 4.5 — what's the difference?
Seedream 5.0 Lite adds web search, logical reasoning, and example-based editing, making it a better model for complex scenes, while improving the overall image fidelity and level of detail.
Seedream 5.0 Lite vs Nano Banana Pro — which is better?
They are both very good image models. They have the same features, but Nano Banana Pro makes images that look more like film, while Seedream makes images that look more like those from a digital camera. It depends what you like, but you can try both on Overchat AI to see which you prefer.
How many reference images can Seedream 5.0 Lite use?
You can have up to 14 reference images — use them to guide location, composition, lighting, style or add props and characters to the scene, all at the same time.
Bottom Line
ByteDance has launched Seedream 5, which is their first image generation model that can also search the web, edit using examples, and understand spatial relationships. The new model is already available on Overchat AI, and you can start creating with Seedream 5 here.
