Seedream 5.0 Pro: price per image, sizes, editing, and who trains on your prompts

The Morse teamPublished November 11, 20268 min read

As of November 11, 2026, Seedream 5.0 Pro is ByteDance Seed's image generation and editing model for professional work, released on July 8, 2026 and priced on BytePlus ModelArk at $0.045 an image up to 2.61 megapixels and $0.09 above that. It outputs at 1K, 1.5K, or 2K (about 4.6 megapixels at most, with no 4K), takes up to 10 reference images, edits the spots you mark with points, boxes, or sketches, and can split a picture into up to 16 transparent layers. ByteDance released Seedream 5.5 on November 9, 2026, and says a Pro version of 5.5 will follow.

We read ByteDance Seed's launch post and model page, BytePlus's Seedream 5.0 pro tutorial, image generation API reference, model pricing page, data processing page, AI models FAQ, and Playground terms, and Volcano Engine's pricing page, all on November 11, 2026. ByteDance's launch post names its own weak spots, saying there is "still room to improve in finer-grained text rendering and pixel-level editing consistency."

Seedream 5.0 Pro at a glance

The model goes by three names. Seed's own pages call it Seedream 5.0 Pro, BytePlus sells it as "Dola Seedream 5.0 pro," under its Dola brand, and Volcano Engine, which prices it in yuan, lists it as Doubao Seedream 5.0 pro. The 260628 in BytePlus's model ID appears to date the build to June 28, 2026, ten days before launch.

How much does Seedream 5.0 Pro cost per image?

Four and a half cents for anything up to 1.5K, and nine cents at 2K. BytePlus's pricing page lists $0.045 for single images "Up to 2.61 million pixels (1.5K or lower)" and $0.09 above that (BytePlus). The first input image is free, and each one after it costs $0.003. Images blocked by content moderation aren't billed. On Volcano Engine the same tiers cost ¥0.30 and ¥0.60, with extra input images at ¥0.02 (Volcano Engine).

We matched the pixel counts in BytePlus's size table to its price tiers:

Every 1.5K preset fits under the line, and the API reference says outright that "1.5K has the same price as 1K" and "also provides better image generation quality." Because the default is 2K, a request that leaves size unset pays the higher tier.

A reseller's price guide from August 6, 2026 puts the cheaper tier "at or below 2.36M pixels" and says 4K at 16:9 was "dated to arrive about a week" after launch (Atlas Cloud). As of November 11, BytePlus's own pages say 2.61 million pixels, and its API reference still caps Seedream 5.0 Pro at 2K. By that line, a 1.5K picture at 4:3, 2,408,448 pixels, would cost $0.09. By BytePlus's, it costs $0.045.

Against the rest of the family on BytePlus, Seedream 5.0 Flash costs $0.018 an image, 5.0 Lite $0.035, and 4.5 $0.04, each with free input images.

What can Seedream 5.0 Pro edit?

Specific spots in a picture, chosen by pointing rather than describing. ByteDance's launch post lists point selection, lasso selection, sketches, color and material swaps, layer separation, and multi-image fusion, and says hex codes such as #3E4A2E set exact colors. BytePlus's tutorial adds boxes, arrows, and coordinates: you mark the input image and say what goes there, and the model blends it in.

Of the models in BytePlus's API reference, only 5.0 Pro and 5.0 Flash split a picture into layers. Set layer_decomposition to true and send one image, and the API returns a base image plus up to 16 layers with transparency, each with its position, stacking order, name, and a description. The launch post shows a poster split into more than 10 layers, with the background behind the subject filled in.

BytePlus's API reference lists what it can't do yet: "Sequential image generation, web search, and streaming output are not currently supported." So it makes one image per request, while 5.0 Lite and 4.5 can return a related set, and it can't look things up the way 5.0 Lite, whose model page advertises "online search capabilities," can.

Does Seedream 5.0 Pro add a watermark?

Yes, by default on BytePlus's API. The watermark parameter defaults to true, which "Adds an 'AI-generated' watermark to the lower-right corner of the image," and you set it to false to leave it off (BytePlus). Every code sample in BytePlus's tutorial sends "watermark": true, so code copied from the docs keeps the mark. The images come back as links that are "valid for 24 hours," and layer splits use the same 24-hour links, so download results the day you make them.

Seedream 5.0 Pro vs Seedream 5.5

Seedream 5.5 is ByteDance's newer model, and 5.0 Pro is the one it measures itself against. In its November 9, 2026 launch post, ByteDance says that compared with 5.0 Pro, 5.5 scored higher on quality and usability across six kinds of work, more than twice the usability rate in film and TV and in office work, and gained "+55.62% for realism in image-to-image tasks" in its own expert ratings (ByteDance Seed). It adds edits across 100 rounds and native transparent backgrounds. These are ByteDance's own tests; we didn't run ours.

5.5 isn't a Pro model, though, and ByteDance says "A Pro version of the Seedream 5.5 series will follow." As of November 11, the Seed models page features 5.5 and doesn't list 5.0 Pro, and BytePlus's model pricing page lists no Seedream 5.5 model ID. For a developer, 5.0 Pro remains the Pro model with a published per-image price.

Does ByteDance train on your Seedream 5.0 Pro prompts?

On the API, not without your permission. On the Playground, yes, unless you opt out.

BytePlus's data processing page says that "Without the customer's prior authorization," ModelArk will not "use Customer Data for its own model training." It processes that data in Malaysia, Indonesia, and the EU or EEA, and keeps inputs and outputs "triggered by the filter" for 180 days in Malaysia. The AI models FAQ, last updated October 24, 2025, says your questions and generated responses in the Playground and Starter apps "may be used to train such models, unless you choose to opt out," and the opt-out is an email to privacy@byteplus.com.

The Playground terms, last updated February 24, 2026, go further. They grant BytePlus, its affiliates, and "third party partners" a "perpetual and worldwide license" to "reproduce, use, store, modify, adapt, publish, translate and distribute" your input and output, and allow storing them outside your region. They restrict Playground use to "your own internal business and non-commercial use," and require users to be 18 or older.

Where your Seedream 5.0 Pro prompts and pictures end up

Whichever ByteDance door you use, the prompt and the picture sit with ByteDance's platform under an account in your name. Morse's Studio lists Seedream 5.0 Pro among its image models, beside FLUX.2, Nano Banana, and Ideogram, and keeps the result on your device instead. Here is the same request in each place, as of November 11, 2026:

Studio images are stored only in your browser, so clearing your browser deletes them and Morse can't restore them. Save any you'll publish. Studio's model menu shows where Seedream 5.0 Pro falls on your plan. The Free plan gives 3 images a day and needs no card, and Pro, at $19 a month or $17 billed yearly, includes unlimited use of Pro image models such as Nano Banana 2 Lite, Qwen-Image-3.0-Pro, and unfiltered image models.

A good Seedream request is mostly copy: the headline, the chart labels, the price list, the same menu in Arabic. That copy can be the most sensitive part of a project, and a Morse chat lets you pick who reads it before it becomes a prompt. Translating poster text into Japanese or Spanish suits Anonymous mode, where GPT, Claude, or Gemini sees the request without knowing it's you and may keep it for a limited time to check for abuse, under its own policy. Unpublished figures for an infographic suit a Private chat with DeepSeek, Kimi, or GLM, since Morse has zero data retention agreements with its inference, search, and other providers. Copy for a launch nobody should see yet belongs in an E2EE chat on Pro, where your browser checks the enclave's proof before anything leaves your device, a guarantee that rests on the enclave hardware and attestation working as designed. E2EE chats can't make images, so the final step, pasting the copy into a Studio request, happens outside the enclave. Whichever mode you pick, the chat itself is stored only in your browser, encrypted.
