Check the selected model, live availability and current quote in the generator before submitting. ## How are tasks charged? The selected model, operation and settings determine the live quote. Review the current quote before submission. Review the checkout amount and renewal terms before paying. ## Do failed tasks restore credits? Provider tasks that reach the failed state follow the existing transactional credit-reversal flow. A completed output that needs creative changes is a separate case. ## What are the homepage images? Original editorial artwork prepared for this website. They are not Seedream 5.5 API test results. Historical model results retain their original model labels. ## Is this an official ByteDance website? No. It is independently operated. Model names and trademarks belong to their respective owners. For account and billing rules, read [the terms](https://seedream55ai.com/terms-of-service) and [pricing](https://seedream55ai.com/pricing). --- # Evaluation method > A repeatable method for comparing image models without turning a small sample into an unsupported universal ranking. ## Controlled comparison 1. Define a real task and explicit pass criteria before generating. 2. Use the same prompt, references, aspect ratio and target resolution where both models support them. 3. Record model identifiers, settings, time, quote, failures and retries. 4. Keep all raw outputs. Do not publish only the best result from one model. 5. Score observable requirements such as spelling, identity, geometry, preserved details and crop. 6. Record correction effort and total credits, not only the first output. 7. Repeat enough tasks to describe the tested workload; avoid claiming an overall winner from one prompt. ## Evidence boundary Workflow illustrations and prompt recipes are not benchmark evidence. Product availability comes from the live model catalog. Prices come from the server checkout catalog. Model quality claims require raw outputs and recorded test conditions.

Replace the examples with facts from your own project. ## Five-part prompt structure State the subject and action, composition, lighting or material, exact visible text, and constraints. Choose one visual direction and one destination shape before adding detail. ## Product image example One cobalt glass bottle centered on pale limestone, soft light from the left, realistic reflections, no lettering, empty space above, square catalog composition. Preserve the bottle silhouette and cap geometry. ## Poster example Create a portrait event poster with one large headline, “SPRING STUDIO”, near the top and the date “18 MAY” below it. Use an uncluttered illustration in the lower half. Add no other words or logos. ## Reference edit structure Name the change first, then list what must remain. Example: replace the background with a pale stone studio wall; preserve product silhouette, label position, cap, reflections, camera angle and crop. ## Review checklist - Inspect spelling and punctuation character by character. - Compare identity, product geometry and labels with the source reference. - Check the crop and output size at the final placement. - Add exact prices, dates and legal copy in an editable manual layer. - Save an accepted baseline and change one observed problem per revision.
