Models & platforms
Seedance, Sora, Veo and Kling are model families; Pollo and SeaArt are creative platforms that organize tools and user resources. Evaluate the version, access route and actual workflow separately. HappyBloom is an independent workspace and is not affiliated with these brands.
Keep the prompt, frame, duration and reference materials consistent. Look at temporal stability, prompt adherence and control over composition instead of judging from a single promotional clip. Check current provider documentation for version-specific options rather than assuming a brand name guarantees a feature.
Pollo's pricing FAQ says deductions depend on tools, models, duration, output quantity and resolution. SeaArt's guide separates daily stamina from credits and describes using stamina first. A credit is not a standardized unit across platforms: include retries, exports and the required quality when comparing a workflow.
Look for access to prompts, reference files, download options, favorites and work history. Decide whether your library is private, how files are organized and what happens when an account or plan changes. HappyBloom's Your Space separates local materials from account-owned cloud items.
The model list currently supports planning and estimated costs. No listed live video provider is connected; curated demos are clearly labeled and do not demonstrate comparative model quality.
