能力与接口#

文本生成多模态理解

下表只列出已在该型号上完成验收的接口、响应方式与输入类型；其他组合会返回 422（如 endpoint_not_verified、response_mode_not_verified、input_modality_not_verified）。

接口	JSON	SSE 流式	WebSocket	已验证输入
Chat Completions`/v1/chat/completions`	支持	支持	不支持	文本、音频、图片
Messages`/v1/messages`	支持	支持	不支持	文本

价格#

官方价格以人民币（CNY）公布，核对日期 2026-10-19。TokenToSea 按官方价格计费、不加价；调用从账户余额（美元）扣除，人民币价格按请求受理时冻结的汇率换算为美元，金额保留 6 位小数并向上取整。

计费项	单价	计量单位
输入 token	¥1.8	每百万 token
图像输入 token	¥3.3	每百万 token
音频输入 token	¥15.8	每百万 token
输出 token	¥0	每百万 token
文字输出 token	¥6.9	每百万 token
多模态文字输出 token	¥12.7	每百万 token
音频输出 token	¥62.6	每百万 token

每次请求先按可能的最高用量预留金额，完成后按供应商返回的实际用量结算并退回差额。计费方式详见计费与结算。

限制#

项目	取值	说明
上下文窗口	65,536 token	厂商文档
最大输出	16,384 token	厂商文档
输出长度参数上限	131,072 token	平台校验 max_tokens 等参数；实际可输出长度以模型为准
默认输出长度	4,096 token	请求未指定输出长度参数时自动填入

响应方式：JSON、SSE 流式。

同一账户最多同时进行 8 个已预留或执行中的调用（平台规则）。
JSON 请求体不超过 48 MB；multipart 上传仅 1 个 file，不超过 25 MB。

完整限制与错误码见用量限制和错误处理。

全部调用示例#

每个示例都包含 cURL、Python 与 Node.js 三种写法，发送完全相同的请求体，并用同一个 Idempotency-Key 查询结果。
