What can Seedream 4.5 do on Kyeo AI?

It supports text-to-image generation and reference-based editing. Useful test cases include multi-image composition, product or character changes, posters, and text-led visuals, but suitability for production depends on your own samples.

How much does a Seedream 4.5 request cost?

Kyeo AI currently charges a fixed 7 credits per request, with the same price for basic and high. Budget for retries, revisions, and the share of outputs that pass review.

Is Seedream 4.5 high always better than basic?

No. In the upstream interface's documentation, basic and high mean 2K and 4K output.

How many references can Seedream 4.5 accept?

Kyeo's editing entry accepts up to 14 JPG, PNG, or WebP images at 10 MB each. The 14-image capacity is a maximum, not a requirement; using only directly relevant references makes conflicts easier to diagnose.

Can I publish Seedream 4.5 output without review?

No. Check copy, prices, dates, people, product details, trademarks, copyright, and legally sensitive statements. Use results from representative tasks and revision rates before adding the model to a recurring workflow.

How should I compare Seedream 4.5 with Nano Banana Pro?

Run both with the same prompt, references, and acceptance criteria. Compare subject preservation, text accuracy, instruction following, usable output size, turnaround time, and Kyeo credit cost rather than relying on model names or vendor showcases.

Seedream 4.5

Kyeo AI exposes Seedream 4.5 for both text-to-image generation and reference-based editing. Text-only requests use the generation route; adding an image switches to the editing route. The `basic` and `high` settings map to 2K and 4K output, and both currently cost 7 credits per request. A 4K label describes output size, not a guarantee of more accurate or more usable content.

What it does best

Kyeo combines Seedream 4.5's generation and editing routes under one model entry and offers two output settings. It is not a universal default; it is one candidate to test against other models on the same material.

Best for

Good test cases include multi-reference composition, product or character changes, poster layouts, and briefs that continue from an existing visual direction.

At a glance

What is this model like?

Selection guide

Test it for multi-image edits

Seedream 4.5 is worth sampling when a brief combines several product, character, or style references. The 14-image capacity is the interface limit, not a recommended target.

Compare other versions when the controls or cost differ

If explicit 1K, 2K, and 4K selection matters, compare Seedream 4.0. If you want to assess basic 2K / high 3K settings at a lower fixed Kyeo price, add Seedream 5.0 Lite.

Run a controlled 2K-versus-4K test

Keep the prompt and references fixed, then run `basic` and `high`. Compare detail, text, subject preservation, and usable dimensions. Both settings cost 7 credits, and the 4K label alone does not establish content quality.

Practical usage insights

Practical observations based on real creative workflows.

The quality field is an output control, not an independent score

In this upstream interface, basic and high map to 2K and 4K output. They do not directly measure prompt adherence, editing consistency, typography accuracy, or aesthetic quality.

Official showcases establish direction, not an outside guarantee

Business usability still depends on your materials, copy, and review criteria.

Capabilities

Seedream: Clear input options

Text-only jobs use `seedream/4.5-text-to-image`. When references are attached, Kyeo switches to `seedream/4.5-edit` and sends them through `image_urls`.

8 ratios and two output settings

The workbench offers 1:1, 4:3, 3:4, 16:9, 9:16, 2:3, 3:2, and 21:9, with basic 2K or high 4K output. Each request currently costs 7 credits.

Prompt and reference limits

Prompts can contain up to 3,000 characters. Editing accepts up to 14 JPG, PNG, or WebP references at 10 MB each.

Use cases

Multi-reference composition and editing

Combine character, product, wardrobe, or style references, while stating what each image contributes and which elements must remain unchanged.

Posters and text-led visuals

Test headlines, short copy, and layout, then proofread every word, price, date, and brand detail before publishing.

Product and campaign variants

Change backgrounds, materials, or composition from an existing visual, with human checks for product appearance, trademarks, and required information.

Prompt tips

List what to preserve and what to change

For each reference, explain its role and identify the subject, pose, color, material, or background details that must remain or may change.

Provide display copy verbatim

For posters or product images, specify the exact copy, language, hierarchy, and placement. Proofread the result rather than treating generated text as approved copy.

Begin with the fewest references you need

14 images is only the editing limit. Start with the minimum set required by the brief, then remove conflicting images or constraints if subjects become confused.

Strengths

One Kyeo entry covers text-only generation and reference-based editing.

ByteDance's official page explicitly demonstrates multi-image editing, reference preservation, layout, and text rendering.

The integration offers 8 aspect ratios plus 2K and 4K output settings.

Fixed 7-credit pricing makes request-count estimates straightforward.

Limitations

Keep fixed samples for long-lived workflows so composition, text, and style consistency can be rechecked after version updates.

High means 4K output.

A 14-image capacity does not mean that adding references will always improve consistency or control.

Generated text, product details, trademarks, and legally sensitive content require human review.

Nano Banana Pro

Nano Banana Pro supports text-to-image generation and reference-image editing on Kyeo AI, with 1K, 2K, or 4K output. Each 1K or 2K request costs 8 credits, while 4K costs 14. Resolution is an output-size tier, not a guarantee of quality, accuracy, or detail.

Flux 2 Pro

Flux 2 Pro on Kyeo supports text-to-image and image editing. A request without an upload uses `flux-2/pro-text-to-image`; attaching one to eight images switches to `flux-2/pro-image-to-image`. Both routes offer seven fixed aspect ratios and 1K/2K, currently priced at 5/7 credits.

GPT Image 1.5 supports generation and editing on Kyeo AI. Text-only requests use `gpt-image/1.5-text-to-image`; attaching references switches to `gpt-image/1.5-image-to-image`. Kyeo exposes 3 aspect ratios and `medium / high` tiers at 4 / 22 credits. OpenAI now marks GPT Image 1.5 as a deprecated previous model, so new work should also benchmark a current model such as GPT Image 2.

Source notes

ByteDance's official page focuses on Seedream 4.5's multi-image editing, preservation of reference details, layout, and dense text rendering. Kyeo's controls, upload limits, and pricing are verified against the local upstream interface documentation and platform configuration: text-only requests use `seedream/4.5-text-to-image`, while requests with references switch to `seedream/4.5-edit`. The upstream interface does not identify the corresponding Volcengine model version or snapshot, so this page does not treat the two sets of IDs as interchangeable.
