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. Your use subject to ByteDance's Terms & Privacy Policies.

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.
What To Consider When Choosing a Provider
- Configuration: Web-connected retrieval changes the latency and determinism profile compared with offline image generation. If your application requires fully deterministic output for the same prompt, factor in the variability that real-time retrieval introduces. See $0.035 for per-image pricing and N/A for the full breakdown.
- Zero Data Retention: AI Gateway does not currently support Zero Data Retention for this model. See the documentation for models that support ZDR.
- Authentication: AI Gateway authenticates requests using an API key or OIDC token. You do not need to manage provider credentials directly.
When to Use Seedream 5.0 Lite
Best for
- Current-Context Generation: Web-connected retrieval grounds outputs in real-time information beyond the training cutoff
- Enterprise Scene Generation: Stronger reference consistency and global knowledge coverage suit professional workflows
- Multimodal Reasoning: Text, reference images, and live web context combine in one generation step
- Knowledge-Heavy Briefs: Visual outputs that depend on accurate, evolving subject matter benefit from retrieval grounding
Consider alternatives when
- Reproducible Output: Seedream 4.0 or Seedream 4.5 produce more deterministic results for the same prompt
- Editing Consistency: Seedream 4.5 targets portrait, small-text, and color-tone preservation directly
- Minimal Latency: Real-time retrieval adds variability that purely offline generation avoids
Conclusion
Seedream 5.0 Lite extends image generation with web-connected retrieval, so outputs can reflect current information rather than relying only on training data. For enterprise workflows that depend on accurate, evolving context, it brings retrieval grounding into the image pipeline.
