Try Seedream 4.5 in the Workbench Run this model interactively, tune parameters, and compare outputs.
Model ID: bytedance-seedream-4-5bytedance/seedream-4.5 is an image generation model. It excels in high-fidelity text-to-image and image-to-image generation with improved consistency, editing capabilities, and realism in physics, lighting, and multi-angle outputs compared to prior versions.Some other noteworthy features of bytedance/seedream-4.5 include multi-reference control (up to 10 images), batch generation (up to 6-15 images), 4K resolution support, and enhanced text rendering.Metric Value Parameter Count Unknown Mixture of Experts Unknown Context Length Unknown Multilingual No Quantized* Unknown
*Quantization is specific to the inference provider and the model may be offered with different quantization levels by other providers.
