[Source](https://www.alibabacloud.com/help/en/model-studio/model-pricing) - **Output:** US$0.4 per 1 million output tokens. [Source](https://www.alibabacloud.com/help/en/model-studio/model-pricing) **Rate conditions:** The displayed pair uses the first listed input-size tier. Singapore; deployment International.

This assumes every token is billed at the displayed rate and excludes any cache, batch, tool, storage or tier adjustments; it is not a quote or measured usage. Check the source's pricing conditions before budgeting. A token rate does not state the price of an app subscription or the full cost of running downloaded weights. ### Which qwen3.5-flash does this page describe? qwen3.5-flash is a model record from **Qwen** in the Qwen family.

The catalog documents **API** access for qwen3.5-flash. [Source 1](https://www.alibabacloud.com/help/en/model-studio/model-pricing) · [Source 2](https://www.alibabacloud.com/help/en/model-studio/text-generation-model) As of the catalog check, this version was marked deprecated. [Source](https://www.alibabacloud.com/help/en/model-studio/text-generation-model) Check the linked lifecycle information before starting a new integration. For API use, confirm the exact model identifier, your account and region, and the endpoint's current limits in the linked documentation. An API listing does not establish access through a consumer subscription. ### What are qwen3.5-flash's context and output limits? The documented **context window is 1,000,000 tokens**. [Source](https://www.alibabacloud.com/help/en/model-studio/text-generation-model) A separate maximum-output value is not established in this record. The context or input figure should not be used as an output allowance. Context, input and output limits describe different constraints. Do not add the figures together to infer a larger window. Check the endpoint's accounting for conversation history, system instructions, tools, media and generated tokens; a documented maximum is not a guarantee of answer quality or a measured usable capacity. ### What can qwen3.5-flash receive and generate?

Reading an image does not establish image generation; a text output listing does not establish speech output. File sizes, formats and media limits depend on the documented implementation. ### What distinguishes qwen3.5-flash? These details come from the linked publisher material for this model.
