The flagship translation large model, comprehensively upgraded based on Qwen3, supports translation between 92 languages (including Chinese, English, Japanese, Korean, French, Spanish, German, Thai, Indonesian, Vietnamese, Arabic, etc.). Performance is significantly optimized, terminology customization is more stable, format restoration is more accurate, domain adaptation is stronger, and translations are precise and natural.
If you have high requirements for translation quality, it is recommended to choose the qwen-mt-plus model; if you prefer faster translation speed or lower cost, it is recommended to choose the qwen-mt-turbo model.

AI Model

frequency_penalty

number

optional

A number between -2.0 and 2.0. Positive values penalize based on the existing frequency of new tokens in the text, reducing the likelihood that the model will repeat the same line word for word. See more information about frequency and presence penalties.

max_tokens

integer

optional

The maximum number of tokens generated when chat is completed. The total length of input tokens and generated tokens is limited by the model's context length.

presence_penalty

number

optional

A number between -2.0 and 2.0. Positive values penalize new tokens based on whether they have appeared in the text so far, increasing the likelihood that the model will discuss new topics. See more information about frequency and presence penalties.

temperature

integer

optional

What sampling temperature to use, between 0 and 2. Higher values (such as 0.8) will make the output more random, while lower values (such as 0.2) will make the output more focused and deterministic. We generally recommend altering this or top_p but not both.

top_p

number

optional

An alternative to temperature sampling is called nucleus sampling, where the model considers outcomes with a top_p probability mass of tokens. So 0.1 means only tokens that make up the top 10% probability mass are considered. We generally recommend changing this or temperature but not both.

top_k

number

required

stream

boolean

optional

If set, partial message increments will be sent, just like in ChatGPT. When tokens become available, they will be sent as plain data server-sent events data: [DONE], and the stream will be terminated by the message. For example code, please refer to the OpenAI Cookbook.

response_format

optional

return_images

search_domain_filter

array[string]

optional

给定一个域名列表，限制在线模型使用的引用仅来自指定域名的 URL。目前白名单和黑名单仅限于 3 个域名。要进行黑名单设置，请在域名字符串开头添加一个 -。

search_recency_filter

string

optional

返回指定时间区间内的搜索结果 - 不适用于图片。可选值包括 month、week、day、hour
