ByteDance Seedream 4.5 covers the full range of visual styles that creative production demands. Each one executed with the kind of accuracy that holds up in the real world.
Common Usecases
Dense labels, fine print, multi-line poster copy, and bilingual layouts all render with sharp, legible characters. No garbling, no melted fonts. What you type in the prompt is what appears in the image, placed exactly where it belongs.

The ByteDance Seedream 4.5 image model is engineered for people who do not settle for anything less than perfection.
Upload multiple reference images and the model accurately identifies, isolates, and applies each one without confusion. Characters, objects, lighting setups, and brand elements coexist in the output without bleeding into each other.

ByteDance Seedream 4.5 image editing understands spatial context with precision. Change a single word, swap one material, remove one person from a group. The rest of the image remains structurally intact. The model edits exactly what the instruction specifies and leaves everything else untouched.

Try Seedream 4.5 free and go from a blank canvas to a production-ready visual without a learning curve. No technical setup, no prompt engineering degree required.

Describe your image, composition, style, materials, lighting, text placement, and any spatial edit instructions. Upload reference images for more customized and controlled generation.

Set your output aspect ratio, and style parameters. Add negative prompts to exclude unwanted elements. Adjust how closely the model follows each individual reference image.

Hit generate and receive your image in seconds. Download at full resolution, ready for commercial use, print, or direct publishing. No post-processing required.
Tested rigorously across benchmarks, Seedream 4.5 came out ahead of top image generation models. Here's exactly what that means for what you can create.
Seedream 4.5 translates complex, multi-clause prompts into accurate visuals with fewer missed instructions and less iteration needed.
Every element in the output looks exactly like how it is described in the prompt. Advanced prompt fidelity, zero approximation.
Improved lighting balance, color harmony, and compositional intentionality. Images feel deliberately designed and styled.
Avoid jumping between different applications. Chatly integrates multi-model AI chat, intelligent search, and image generation in one platform, allowing you to stay focused and seamlessly transition from ideas to outputs.

Chatly's AI Chat is designed to align with your thought process. Whether you're deciphering a complex issue, investigating a new concept, or deliberating a decision, it provides the clarity and context you require.

Chatly's AI Web Search allows you to pose questions as you naturally would and receive answers sourced from real-time information. There’s no need for manual browsing or dealing with multiple tabs. Just precise, current information.

Chatly gives you the speed, quality, and creative range to bring any visual idea to life. No design experience required. No compromises on output. Just describe what you need and generate it in seconds.
Across 725 multi-language prompts on MagicBench, Seedream 4.5 showed significant improvement over Seedream 4.0 on prompt adherence and visual alignment. Complex, multi-clause instructions are understood as a whole. What you describe is what you get, even when the prompt is long and layered.

Generate at resolutions up to 4,096 × 4,096 pixels with fine detail that survives full-screen display, large-format print, and 100% zoom inspection. Fine print stays readable. Skin pores stay visible. Material textures hold at maximum resolution.

Facial features, color palettes, material finishes, and lighting setups from reference inputs are carried into the output with strict accuracy.
Highlight an area to edit and the model complies leaving the rest of the image alone. Background, composition and untargeted subjects survive.
Small-font text, multi-line layouts, and dense informational copy render with clean character edges and correct shapes across both Latin and CJK scripts.
Complex surfaces behave with physically plausible light responses. Everything works as expected without requiring additional prompt guidance.
When working across multiple reference inputs or generating image sequences, the model maintains stable identity, style, and compositional logic throughout.
Layout decisions reflect an understanding of design intent rather than random distribution. The model produces compositions a designer would appreciate.

Chatly's AI Image Generation bridges the gap between concept and visual representation. Simply write a prompt, define your parameters, and receive high-quality images tailored to your specific needs. Perfect for presentations, campaigns, or creative experimentation.
