WaveSpeedAI,Tue Sep 09 2025

Over the past week, the viral sensation of Nano-Banana dominated headlines, signaling that multimodal AI is entering public consciousness at an unprecedented pace. Yet these discussions often remain confined to the research and exploration phase, still some distance from true enterprise-level implementation.

Now, Seedream 4.0 officially launches on the WaveSpeedAI platform, transforming this trend into a tangible breakthrough for scalable applications. With its exceptional capabilities in complex scene understanding, image sequence generation, aesthetic cognition, and logical reasoning, Seedream 4.0 represents a major leap forward in multimodal technology. Powered by WaveSpeedAI’s high-performance inference engine, it not only significantly boosts generation speed and efficiency but also achieves true large-scale real-time deployment for the first time. This enables enterprises and developers to directly apply cutting-edge models to production-level tasks.

Complex Scene Comprehension

Seedream 4.0 excels at complex scene comprehension, beyond what we have seen from previous image generation models. Prompts:A bustling vertical city in the year 2242, where futuristic, organic-shaped skyscrapers made of white polished material and shimmering glass are interwoven with lush nature. Waterfalls cascade down the sides of buildings into crystal-clear canals where small, elegant boats travel. Sky-bridges covered in flowers and trees connect the towers. The atmosphere is bright, optimistic, and full of life.

Premium Image Generation from References

Stop laboriously adjusting images,let AI craft stunning visuals from your references.Try Seedream 4.0—it uses AI to automatically assemble them for you. With the tool, you can refer up to six images to create one interesting composite image.

Prompts:Based on this logo, create a visual design system for an outdoor sports brand named “GREEN,” including packaging bags, hats, paper boxes, cards, wristbands, lanyards, etc. The primary visual color scheme should be green, with a playful, minimalist, and modern style.

Switch to Any Style

In terms of stylization understanding, Seedream 4.0 achieves true artistic transformation. Beyond common styles, Seedream 4.0 excels at Van Gogh-inspired paintings, Makoto Shinkai-style cinematic lighting effects, and intricate styles like clay sculptures. Stylized Features are particularly useful for creating virtual character avatars.

Not only can it generate virtual avatars, but it can also customize your stylized products.

Powerful Logical Reasoning

Last but not the least,Seedream 4.0 achieves a new breakthrough: not only can it edit individual images, but it also understands context and generates up to nine coherent, story-driven images in a single batch based on prompts. It is highly compatible with creating sequential comics.

Additionally, multi-theme generation is another great option.
