Workflow on Mivo
Open Generate Studio and switch to the AI Image tab. Select Seedream 5 Pro from the model list, choose your aspect ratio and quality level, then write your prompt. For image-to-image editing, upload reference images and describe the transformation you want.
Generate multiple images in parallel with different seeds for variety. The studio supports up to 5 concurrent jobs per model, so you can iterate quickly and pick the best result.
Once satisfied, download your image or publish it directly to your Mivo profile. All generated images are archived in your generation history for easy access.
Prompt guidance
Seedream 5 Pro responds well to descriptive, detailed prompts. Include subject, setting, lighting, mood, camera angle, and style references. The model accepts up to 3,000 characters, so be specific. For best results, describe the final image you want, not the process of creating it.
For image-to-image editing, describe what you want to change or enhance. Reference images provide visual context, so your prompt should focus on the transformation rather than restating what's already in the images.
Prompt blueprints
Product photography
Professional product photo of [PRODUCT] on clean white background, studio lighting, soft shadows, high detail, 4:3 aspect ratio, photorealistic
Lifestyle marketing visual
Lifestyle photo of [PERSON] using [PRODUCT] in [SETTING], natural lighting, warm tones, candid moment, 9:16 vertical, social media ready
Image-to-image style transfer
Transform the reference image into a watercolor painting style, maintain the composition and subject, add soft brush textures and pastel color palette
Best practices
Start with 1K (basic) quality for drafting and iteration. It's faster and cheaper, allowing you to explore multiple concepts before committing to 2K output for final production. Use the default 1K setting and switch to 2K only when you need higher detail.
For multi-image reference editing, provide diverse angles and styles of your subject. The more visual context the model has, the better it can blend references into a cohesive output. Use all available reference slots when possible.
Always verify text rendering in generated images. While Seedream 5 Pro has improved text capabilities, complex phrases and non-English text may still require post-processing with image editing tools for pixel-perfect results.
