Seedream 5.0 Lite

Seedream 5.0 Lite is an image generation model that introduces web-connected retrieval to the Seedream line. It fuses real-time online information with multimodal generation, helping the model produce images aligned with current facts at $0.035 per image.

About Seedream 5.0 Lite

Seedream 5.0 Lite is the first Seedream model to introduce web-connected retrieval. During generation, the model can fetch real-time information from the web and fuse it with its multimodal generation capabilities. This is useful when the visual output needs to align with current facts, recent events, or evolving subject matter that a training-cutoff model would miss.

The Lite designation reflects positioning rather than a stripped feature set. Seedream 5.0 Lite suits production workflows that want web-grounded image generation without the cost profile of a flagship release. ByteDance highlights upgraded reasoning, broader global knowledge coverage, stronger reference consistency, and improved professional scene generation tuned for enterprise workflows.

Like other Seedream models, Seedream 5.0 Lite supports multimodal inputs. You can combine text prompts with reference images, and the retrieval system layers on top of that input rather than replacing it. The result is image generation that can reason over both the prompt and live context retrieved during the request.

Seedream 5.0 Lite is a dedicated image generation model. Call it through the AI SDK's generateImage function with the model set to bytedance/seedream-5.0-lite. AI Gateway handles authentication and provider routing.
