Seedream 4.5 Edit Free: Consistent Image-to-Image, Sharp Text and Facial Details on playground and API | RunComfy

bytedance/seedream-4-5/edit

Bytedance's Seedream 4.5 Edit model delivers professional 4K image manipulation with enhanced prompt understanding, available instantly via RunComfy's playground and API.

The recommended length is no more than 600 English words. If the prompt is too long, the information may become scattered. The model might ignore details and only concentrate on the main points, resulting in a image with missing elements.
Upload 1~14 images. The format must be jpeg or png

Introduction to Seedream 4.5 Edit

Seedream 4.5 is Bytedance's premier generative AI model designed for high-fidelity image editing. This advanced model interprets complex natural language instructions to transform existing images while maintaining structural consistency. For developers, Seedream 4.5 Edit on RunComfy can be used both in the browser and via the Playground API, so you don’t need to host or scale the model yourself.

Frequently Asked Questions

How do I transition from the Playground to the API?

Developers can easily switch to production by using the Seedream 4.5 Playground API. Once you have tested your prompts in the UI, simply call the endpoint programmatically. You can find the API integration details and documentation on the Seedream 4.5 Edit API page.

How does Seedream 4.5 compare to Seedream 4.0?

Compared to its predecessor, Seedream 4.5 offers significantly better context understanding for long prompts and higher output fidelity. While Seedream 4.0 was limited to HD resolutions, Seedream 4.5 delivers true 4K texture details and handles complex instruction-based editing with greater accuracy.

What inputs are required to use the Seedream 4.5 Edit mode?

To run the Seedream 4.5 Edit model, you must provide a prompt describing the desired changes and an image_url serving as the source. The model uses the source image as a structural reference while applying the semantic changes requested in your text prompt.

Does Seedream 4.5 support image generation from scratch?

This specific page is for the Edit variant, which modifies existing images. If you need to generate images from scratch using the same high-quality architecture, you should use the Seedream 4.5 Text-to-Image model on RunComfy.

What is the expected latency when running Seedream 4.5?

RunComfy hosts Seedream 4.5 on high-performance cloud GPUs to minimize latency. While 4K generations naturally take longer than 1K images due to the increased pixel count, the inference speed is optimized for interactive creative workflows and near-real-time iteration.

How does Seedream 4.5 perform?

Seedream 4.5 is engineered for high structural consistency. It minimizes hallucinations by strictly adhering to the provided image_url for unedited areas, ensuring that only the elements specified in your prompt are altered while the rest of the composition remains intact.
