Seedream 4.5 deployment guide
Seedream 4.5 is indexed here as a image model by ByteDance Seed, with 1 provider endpoint from Seed. The comparison preserves each exact OpenRouter routing tag so pricing and performance observations can be connected to the route an application would actually request.
The model publishes a 4.1K-token context window. It accepts image, text input and returns image output. 5 distinct supported parameters appear across the listed routes. Confirm limits on the specific endpoint rather than assuming every host exposes the same configuration.
At least one image is published consistently across the listed endpoints, allowing a direct price chart for output image. Other charges remain in the table using OpenRouter’s exact billing labels.
No model-format or quantization labels are currently published. Availability, rate limits, and regional support can change independently of catalog pricing, so confirm the selected routing tag before production deployment.
