Seedream 4.0 is the newest release in ByteDance's line of AI image generators, and it's already being called a record-breaking model. In this article, we'll cover what Seedream is, who created it, why the new Seedream 4.0 matters, and how you can start creating with it today on Krea.

Seedream is an advanced AI image generator that turns text prompts into vivid, high-quality images. Developed by ByteDance (the company behind TikTok), it uses a 12-billion parameter architecture to capture context, style, and details more accurately than many peers like DALL·E or Stable Diffusion.

You can describe a scene ("a cyberpunk street at night in watercolor style"), and Seedream AI will produce a fitting image. It also supports editing: upload an existing image, give instructions, and it adapts the picture accordingly.

Seedream 4.0 (aka Seedream 4) is the most advanced version yet, and it sets a new benchmark for AI art. Here's what stands out:

• Unified Creation + Editing – One model handles text-to-image and precise edits.
• Multi-modal inputs – Mix text prompts with up to 6 reference images, and generate up to 9 outputs at once.
• 4K resolution – Native ultra-HD outputs, with richer detail.
• Reasoning ability – Understands logic and facts, making outputs more coherent and educational.
• Faster generation – Images in as little as 1.8 seconds.
• Better text rendering – Legible signs, posters, and labels, beating many competitors.

Seedream 4.0 has already topped benchmark leaderboards for text-to-image and editing, with many reviewers noting it surpasses Google's newest models in speed and text accuracy.

Seedream was built by ByteDance's Seed team to merge creation and editing into one system. Earlier versions split these tasks across separate models, but Seedream 4 combines them seamlessly.

Why? The team wanted an all-in-one creative engine that works faster, at higher resolution, and with stronger reasoning. With support for 4K output and generation speeds over 10× faster than Seedream 3, it's designed for real creative workflows—from hobbyist experiments to professional design, advertising, and entertainment.

The easiest way to try Seedream 4.0 is on Krea. Here's how:

1. Go to Krea – Sign up or log in.
2. Select Seedream v4 – Make sure it's the chosen model.
3. Enter your prompt or upload images – You can mix text with references for complex results.
4. Click Generate – In seconds, you'll see high-res images. Refine your prompt to iterate quickly.

Because Seedream is integrated into Krea, you can experiment freely, browse community examples, and save outputs—all without needing powerful hardware. If you want to edit photos, remove objects, or create themed sets, Seedream 4.0 on Krea makes it straightforward.

Other platforms like OpenArt and ImagineArt also host Seedream, but Krea remains one of the most accessible hubs.

Seedream 4.0 combines speed, flexibility, editing, and 4K quality in one package. Built by ByteDance, it's designed to be more than an art toy—it's a professional-grade creative tool. Best of all, you don't need technical setup to use it: just visit Krea, enter your idea, and watch Seedream AI bring it to life.
