Seedream 5: Image Model Guide | FluxoKit Docs

Seedream 5 is ByteDance's specialist engine for UGC and creator aesthetics. In 2026 it is the default pick for organic TikTok ads, Reels, and any channel where "shot on a phone" beats "shot in a studio". On FluxoKit, paid per image.

Why Run Seedream 5 on FluxoKit

Seedream is the engine ByteDance uses internally to feed the TikTok algorithm with creative. Reaching it directly asks for a ByteDance or Higgsfield developer account, USD billing, English prompts, and the official site queue. On FluxoKit you open the canvas, describe the scene in plain language, and the Prompt Enhancer tunes the prompt automatically.

Seedream 5 sits beside Nano Banana, GPT Image, Flux 2, and 80+ other models in one plan.

How to Use

1. Open the studio at /workflow.
2. Select Seedream 5 in the image panel.
3. Describe the scene. For UGC, think "organic TikTok post": casual environment, natural light, phone-style angle.
4. Adjust aspect ratio (9:16 for TikTok and Reels, 4:5 for Instagram, 16:9 for YouTube).
5. Generate. In seconds you get a creator-style image.

Where Seedream 5 Wins

• Organic UGC on TikTok and Reels. Default pick. The "shot on a phone" aesthetic that the algorithm rewards.
• Organic ads on Meta. Ads that do not look like ads. Higher CTR than polished creative at volume.
• Creator content. Instagram covers, YouTube thumbnails with organic vibe, before-and-after coach photos.
• Source frames for I2V. Seedream 5 plus Seedance I2V is the most efficient combo for creating UGC video from scratch.

When Not to Use Seedream 5

Seedream is a specialist, so it is honest about where another engine wins:

• Premium hero shots. Use Nano Banana or GPT Image for a controlled, cinematic look.
• Professional portraits. Use Higgsfield, the specialist in skin and editorial lighting.
• Covers and mockups with text. Use GPT Image, which renders legible text inside the artwork.
• Editorial illustration. Use Flux 2 for stronger style control.

All of them open in the same canvas, so picking the right one per creative is a click, not a new subscription.

What to Put in a Seedream 5 Prompt

The goal is "shot on a phone", not "shot in a studio". Anchor the prompt in everyday context:

• Setting. A home kitchen, a car, a bedroom, a bathroom mirror. Domestic and casual reads as authentic.
• Light. Natural window light or overcast daylight, not controlled studio strobe.
• Angle. A phone-style angle or a casual selfie framing.
• Vibe words. "Creator aesthetic", "casual photo", "organic UGC" steer the model toward the look the feed rewards.

Avoid "professional studio" and "controlled lighting". Those produce a hero shot, which is the opposite of UGC.

Seedream Family on FluxoKit

Use 5 as the default and drop to an earlier tier only for a specific reason.
