Supported Aspect Ratios

All models support flexible aspect ratios:

Tips for Best Results

• Be specific in your prompt — "A golden retriever playing in autumn leaves, soft afternoon light, shallow depth of field" beats "dog in park"
• Use reference images when available (Nano Banana, FLUX 2 Pro) for consistent style
• Start cheap, refine expensive — Use Seedream 4 (1,000 credits) to test prompts, then switch to a premium model for the final version
• Match the model to the task — Need text in the image? Use Seedream 4. Need photorealism? GPT Image 1.5. Need 4K? Seedream 4.5.
• Try multiple models — The same prompt produces very different results across models. Experiment!
