Seedream 3.0 is ByteDance's flagship image generation model — and it's one of the best-kept secrets in AI. While most developers know about DALL-E, Midjourney, and Flux, Seedream consistently produces photorealistic images with exceptional text rendering, detail accuracy, and aesthetic quality that rivals or exceeds Midjourney v6.
The problem? Seedream is served through ByteDance's Volcengine (火山引擎) platform, which requires a Chinese phone number, Chinese payment methods, and navigating Chinese-language documentation. Until now.
💡 Seedream powers TikTok's internal creative tools. The same model that generates content for billions of users is now accessible via API.
| Model | Best For | Speed | Price |
|---|---|---|---|
| seedream-3.0 | Highest quality, photorealistic | ~5s | $0.01/img |
| seedream-2.0 | Fast general purpose | ~3s | $0.008/img |
Both models are also available as nano-banana-2 (Seedream 3.0's alternate ID, based on its Gemini-era codename) for backward compatibility.
