Seedream 4.5 combines text-to-image generation and reference-guided image editing. Write a new visual brief or provide one to ten images for the person, object, setting or composition you want to use. Describe their relationships, the text to include and the materials or style to create, then choose an aspect-ratio preset, 2K or 4K size preset, or custom positive integer dimensions. Request one to fifteen images for a batch and review the results for subject appearance, object placement, rendered wording and the changes you specified.
Seedream 4.5 is developed by ByteDance Seed. Vidgo provides access to the model. Model names and trademarks belong to their respective owners.Choose Text to Image to develop a scene from words, or Image Editing to work with existing subjects, objects and compositions. Explain the role of each ordered reference, then set the size and requested count for the finished image workflow.

Text generation describes the full scene in a prompt. Editing adds one to ten image URLs to guide identity, objects, location or the source layout. Both tasks accept output size and the number of requested images, allowing the same written brief to be tested with the inputs that match your project.

Specify how people, objects and environments fit together, then explain the geometry, text or material treatment to retain or change. Existing examples show a labeled station illustration, a multi-reference shoreline scene and a drawing transformed into a miniature diorama.
Describe the major structures, their relationship and any labels in the prompt. The ridge-station cutaway record asks for a readable interior illustration. Inspect the spatial arrangement and wording when preparing an educational or design explanation.
Assign separate images to the boy, toy sailboat and loch shoreline. The recorded prompt explains his crouching pose, the boat’s construction and its placement in the water, then requests matching morning light and reflections. Review those relationships in the combined photograph.
Supply the drawing and preserve its layout while describing physical materials. The picnic record turns the tree, treehouse, family, dog and backdrop into clay, felt, wood and fabric elements photographed on a tabletop. Compare the result with the source composition and requested textures.
Describe the person’s activity, clothing, surroundings and light. The monsoon net-mender record offers a photographic scene for reviewing how hands, net fibers, wet surfaces and atmospheric lighting appear together. Use the image as a visual concept and inspect the details relevant to your project.
Select an aspect-ratio preset, a 2K or 4K preset, or custom positive integer width and height. Set n from 1 to 15 for the requested output count. Review the generated files at the intended dimensions and compare their composition and detail with the brief.
The first record uses three images for a boy, a toy sailboat and a misty loch, then describes him placing the boat on the water with consistent scale, light and reflections. The second starts from a child’s crayon drawing and requests the same layout as a photographed tabletop diorama. Compare all original inputs and actual outputs using the complete prompts to inspect appearance, object relationships and material changes.
Combine the three reference images into one natural photograph. Use the boy from image 1 with the same face, curly dark hair, freckles, red hooded raincoat with wooden toggles, navy trousers and yellow rubber boots. Use the exact toy sailboat from image 2: teal wooden hull with a white stripe, cream canvas sail with the stitched patch and dark blue painted star, red string at the bow. Place them on the misty loch shoreline from image 3. The boy crouches on the flat rocks at the water's edge, seen in three-quarter side view, gently setting the sailboat onto the calm water with both hands while holding the red string; small ripples spread around the hull. Keep the pebbles, rust bracken hills and misty pines of the location. Soft overcast morning light, consistent scale and shadows, realistic reflections in the water, a quiet tender moment, no text, no watermark.
Turn this child's crayon drawing into a photograph of a handcrafted miniature diorama built on a tabletop, keeping the exact same composition and layout. The big tree with the round green crown and the wooden treehouse with its rope ladder stays on the left; the family of four sits on the red and white checkered picnic blanket on the right with the basket and watermelon slice; the spotty black-and-white dog runs in the same place; the yellow sun sits in the top right corner with the blue clouds on a painted backdrop; green grass and two red flowers along the bottom. Make everything tangible: sculpted clay figures with simple friendly faces, a real twig tree trunk with felt leaves, a tiny balsa-wood treehouse, fabric blanket, flocked grass. Macro photography with shallow depth of field, soft warm window light, tilt-shift miniature feeling, no text, no watermark.
Prepare a written layout, separate visual references or an existing drawing, then define the relationships and changes you want to see. Create explanatory illustrations, narrative scene concepts, revised signage or miniature-style images. Inspect text, subject detail and material treatment before using the results in a design review, presentation or application.
Write the major spaces, their connections and the labels to include. Generate a cutaway illustration and review the resulting spatial organization before placing it in a presentation concept.
Prepare character, object and location images and explain the intended interaction. Inspect pose, contact, scale and reflections in the combined image for a storyboard or narrative proposal.
Supply the drawing and name the layout elements to preserve. Describe clay, fabric, wood and other physical materials, then review the generated tabletop scene as a prop or exhibition concept.
Provide a clear source image and write the exact replacement text along with the surfaces and surrounding layout to retain. Inspect every word and its placement before using the edit in a signage or graphic-design study.
Choose the output size and set n from 1 to 15. Review the total estimate, generate the batch and inspect each image for the subject relationships and details required by the project.
Retain the prompt, ordered image URLs, size and count from your online test. Submit the corresponding API task and track completion to retrieve the image URLs for your application.
Seedream 4.5 estimates a request using its current image rate multiplied by n, the requested output count. Its current Vidgo configuration applies the same rate across supported size options. The dynamic table shows the starting rate for one requested image; configure the actual size and batch count on the task page to review the complete estimate before submission.
| Model | Provider | Workflow | Max image inputs | Resolution presets | Starting rate |
|---|---|---|---|---|---|
| Seedream 4.5 Text to Image | ByteDance | Text to Image | Not applicable | 2K / 4K | $0.025 / requested image |
| Seedream 4.5 Edit | ByteDance | Image Editing | 10 | 2K / 4K | $0.025 / requested image |
Test your creative brief online, then bring the verified request into your application.
Enter the prompt and provide one to ten ordered references for editing. Select an aspect-ratio or 2K/4K preset, or enter custom positive integer dimensions, and set n from 1 to 15. Review the estimate and inspect the returned images for composition, text, materials and the requested changes.
Choose a task, inspect its settings and cost, and follow the result from an online test to an authenticated API request.
Choose Text to Image when the composition starts with a written brief. Choose Image Editing when photographs, illustrations or other references already define the subject, object, setting or visual style. Explain the role of each input and the result you want to create.
Open the matching task, enter your brief and supply the required images. Review the generated result against subject appearance, composition and the requested changes before carrying the workflow into a project.
Set the output size and batch count on the task page, then review the image rate and total estimate. Plan the requested count around the number of compositions you want to inspect at that size.
Read the actual prompt and inspect its source images and result together. Use those examples to understand how to assign input roles and describe the details to preserve or change in your own request.
Retain the task ID returned by the API to query status and retrieve completed file URLs. Use your online generation history to review earlier results and the creative direction you tested.
Use the documentation linked from each task for its exact model identifier, accepted inputs, authentication and response format. Integrate the same task you tested online so its media and settings match the request.
