Core seedream 4 api Features

The seedream 4 api uses a continuous video-tokenization architecture rather than simple frame sampling. This allows seedream to track objects and maintain identity persistence across video clips up to 120 seconds long. This native spatio-temporal reasoning makes seedream exceptionally reliable for security monitoring and detailed action summarization tasks compared to traditional multimodal models that often lose context between frames.

No. When you access seedream through GPTProto, you are protected by a Zero Data Retention (ZDR) agreement. None of the images, videos, or text inputs processed by the seedream 4 api are used by the vendor for model training or refinement. This makes seedream suitable for sensitive industrial environments, medical imaging assistance, and private enterprise applications where data security is a non-negotiable requirement.

In benchmarks focused on technical schematics and small-font legal documents, the seedream 4 api demonstrates sub-pixel precision that often outperforms GPT-4o. While GPT-4o is a strong generalist, the seedream architecture is specifically tuned for high-resolution visual interrogation. This specialized focus allows seedream to maintain accuracy at extreme aspect ratios and within dense visual environments common in manufacturing.

For text-only interactions, the seedream 4 api typically sees a Time-to-First-Token (TTFT) of approximately 400ms. When processing multimodal inputs like high-resolution images or 120-second video clips, latency scales with the file size but generally stays under 2.5 seconds. GPTProto optimizes these seedream requests through high-speed routing to ensure your application maintains a responsive user experience despite the heavy visual data.

Transitioning to the seedream 4 api is straightforward as the API remains backwards compatible with the 3.5 series. You simply need to update the model string in your request to 'seedream 4.0 250828'. Note that seedream 4.0 enforces stricter JSON schema validation, so we recommend testing your structured output parameters to ensure compatibility with the updated reasoning engine and its native 'json_object' support.

While seedream is superior for visual and spatial tasks, it may not be the best choice for pure textual logic or high-variance creative writing. For philosophy-heavy reasoning or long-form fiction, models like Claude 3.5 Opus might provide more nuanced prose. Additionally, seedream is not intended for sub-100ms real-time feedback loops, such as competitive gaming, due to the significant inference overhead required for its deep video analysis.
