What is Seedream v4.5 and who made it? +
Seedream v4.5 is an AI image generation model developed by ByteDance (the company behind TikTok). It's designed for professional and commercial visual creation — e-commerce, brand assets, marketing, and concept art. On vivago AI you can use it for free without needing a ByteDance or Volcengine account.
Is Seedream v4.5 free on vivago AI? +
Yes. vivago AI has a free plan that gives you daily credits you can use with Seedream v4.5 and v4. No credit card is required. If you need more generations, paid plans start from $6/month (Basic, 1,000 credits). Watermark-free downloads are included on all paid plans.
What's the actual difference between Seedream v4.5 and v4? +
v4.5 is faster (30–40%), has significantly better text rendering (clearer logos and labels), stronger consistency across multiple generations, and supports up to 10 reference images. v4 is excellent for creative range — concept art, illustrations, and experimental styles. If you're doing commercial production work, choose v4.5. If you're exploring creative ideas, v4 is great too.
Does Seedream v4.5 keep characters consistent? +
Yes — this is one of its strongest features. Facial features, hairstyle, proportions, and clothing remain stable across different poses, angles, lighting, and backgrounds. You can upload reference images to lock a character's appearance across an entire series or campaign.
Can I use my own photos as reference images? +
Yes. Seedream v4.5 supports up to 10 reference images per generation on vivago AI. You can upload your product photos, portraits, or mood-board images and the model will maintain the key visual details — color, texture, identity — in the output.
How good is the text rendering — can it write readable text in images? +
Significantly better than most AI models. Seedream v4.5 renders logos, labels, small print, multi-line layouts, and bilingual text clearly and legibly. It's not 100% perfect for every complex typography task, but for marketing posters, packaging mockups, and social creatives it's production-ready.
Does it work on iPhone and Android? +
Yes. vivago AI has native apps for iOS and Android, as well as the web. You can generate images with Seedream v4.5 from any device. Projects sync automatically so you can start on mobile and continue on desktop.
Can I use Seedream-generated images commercially? +
Yes. vivago AI's Plus ($20/month) and Pro ($60/month) plans include full content ownership rights for commercial use. The free and Basic plans are best for personal and experimental use. Always check the latest terms at vivago.ai/pricing for the most current information.
