Comment fonctionne Seedream 5

Trois étapes de l'idée à l'image finale. Propulsé par le raisonnement visuel en chaîne de pensée.

  1. 1

    Describe What You Want

    Type a natural-language prompt. You can be specific ("a corgi wearing aviator sunglasses, studio lighting, shallow depth of field") or loose ("a cozy autumn coffee shop"). Seedream 5 understands both. Upload reference images if you want to lock a character's face, a brand style, or a product. Structured prompts help, but aren't required — the model fills in sensible defaults.

    Seedream 5 Reasons Through Composition

    This is what's new in Seedream 5: chain-of-thought reasoning. Instead of generating pixels greedily, the model first plans composition, lighting, color palette, and subject placement — then generates. It can pull in real-time web search for current references (events, products, locations) rather than relying on stale training data. You see progress stream via SSE as the image builds.

  3. 3

    Edit, Iterate, Download

    Not perfect on the first try? Use plain-English edits ("make the sky warmer," "remove the lamp," "give her a red jacket"). Or use precision editing to change one element while keeping the rest. When ready, download your finished image. Need maximum resolution? Seedream 4.5 outputs native 4K — 3840×3840, 3840×2160, or 2160×3840. All outputs include commercial-use rights.

5 Pro Tips

lightbulb#1

Start broad, then refine. One vague prompt + three targeted edits beats one overly-engineered prompt.

lightbulb#2

Reference images lock identity. Upload up to 10 reference images for a character — Seedream 5 keeps the face consistent across completely different scenes.

lightbulb#3

Text prompts that read as sentences beat keyword lists. "A woman laughing in a sunlit kitchen" outperforms "woman, laughing, kitchen, sunny, portrait."

lightbulb#4

Use 1:1 for social, 16:9 for hero images, 9:16 for vertical video thumbnails. Choose early — switching aspect ratio mid-iteration burns credits.

lightbulb#5

When in doubt, ask Seedream to "think about the composition" in the prompt itself. Chain-of-thought reasoning triggers on cues like "plan the shot" or "arrange the scene thoughtfully."

Questions frequemment posees

Non. Le raisonnement en chaîne de pensée de Seedream 5 complète des valeurs par défaut raisonnables pour les prompts courts. Les prompts détaillés vous donnent plus de contrôle, mais les prompts courts fonctionnent bien pour la plupart des explorations créatives.

Cela dépend du modèle. Seedream 5 Pro rend jusqu'à 2720×1530, Seedream 5 Lite jusqu'à 3072px, et Seedream 4.5 produit du 4K natif en trois ratios : 3840×3840 (1:1 carré), 3840×2160 (16:9 paysage), 2160×3840 (9:16 portrait). Pas besoin d'upscaling — prêt à imprimer.

Oui. Décrivez l'édition en langage naturel ("change la veste en rouge") ou utilisez l'édition de précision pour changer un élément tout en gardant le reste. Les éditions coûtent des crédits comme une nouvelle génération.
