seedream-5-lite模型特点

核心能力

能力一览与工程实践价值

Unified multi-mode testing

Switch across Text-to-Video, Image-to-Video, R2V, and Video Edit in one place.

Parameter-first validation

Iterate quickly on prompts, durations, and references before production rollout.

Production-ready handoff

Minimal request/response structure helps you move stable configs into API workflows.

如何使用 seedream-5-lite API

Fill prompt and key parameters.
Run, inspect output structure, then iterate.
Move stable settings into production API.

关键参数

参数	类型	必填	默认值	取值范围	说明
model	string	是	gemini_omni	-	Model identifier. Use the fixed value `gemini_omni`.
prompt	string	是	-	-	Main instruction describing the subject, action, scene, and style.
aspect_ratio	string	否	16:9	16:9 \| 9:16	Video aspect ratio. Defaults to `16:9`, corresponding to landscape or portrait output.
duration	integer	否	6	6 \| 10	Output duration in seconds. Defaults to `6` and currently supports only `6` and `10`.
resolution	string	否	720P	720P	Output resolution. Currently only `720P` is supported; if omitted, the default value is used.

常见错误

400 invalid_request_error

触发条件: Request payload misses required fields or has invalid field types.

修复建议: Validate model, mode, and input schema before request.

重试策略: Retry only after fixing payload; avoid blind retries.

401 authentication_error

触发条件: Missing Authorization header or invalid API key.

修复建议: Verify Bearer token format and API key scope.

重试策略: Retry after auth fix; rotate key if repeated failures continue.

429 rate_limit_exceeded

触发条件: Request rate, concurrency, or current quota hits upstream rate limiting.

修复建议: Apply exponential backoff first, then review request rate, concurrency, and quota usage.

重试策略: Use exponential backoff (e.g., 1s/2s/4s) with jitter; if it persists, reduce submission pressure.

500 internal_error

触发条件: Transient upstream error or internal processing failure.

修复建议: Capture request id and trigger retry workflow.

重试策略: Retry 2-3 times with short delays; escalate if persistent.

FAQ

When should I use seedream-5-lite?

Use it to validate video concepts quickly, compare mode behavior, and converge prompts before API rollout.

How do I choose Text-to-Video vs Image-to-Video?

Use Text-to-Video when you only have instructions; use Image-to-Video when you already have key frames or composition.

What is the difference between R2V and Video Edit?

R2V focuses on reference-guided generation, while Video Edit focuses on modifying existing video assets.

图像视频模型报错：invalid apitype: -1

这类错误通常说明接口走错了。图像和视频模型一般不走 chat 接口，而是按对应文档发起 HTTP 任务请求，并通过任务状态接口轮询结果。排查时建议先看用户的实际请求代码、请求地址和请求体。

用户进行生成图片/视频的任务时出现任务失败，但是扣款

先让用户提供任务日志或截图，重点看是否出现了输入或输出 token 统计。如果有这类 token 记录，大概率是用户把图片/视频模型走成了 chat 接口；这不是正确用法。图片和视频模型通常是异步任务接口，需要通过 HTTP 请求先提交任务，再拿到任务 ID 轮询状态，详细以对应文档为准。
