[Source](https://www.alibabacloud.com/help/en/model-studio/text-generation-model) The recorded model identifier or checkpoint is `qwen-long`. Use that exact identifier when checking documentation or a provider listing. [Source](https://www.alibabacloud.com/help/en/model-studio/text-generation-model) ### How can you access qwen-long? The catalog documents **API** access for qwen-long. [Source](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 qwen-long's context and output limits? The documented **context window is 10,000,000 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 qwen-long receive and generate? Documented inputs: **text**. [Source](https://www.alibabacloud.com/help/en/model-studio/text-generation-model) Documented outputs: **text**. [Source](https://www.alibabacloud.com/help/en/model-studio/text-generation-model) Input support and output generation are separate capabilities. 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 qwen-long? These details come from the linked publisher material for this model. Reported capabilities and training descriptions are publisher statements, not independent test results. **Documented feature boundaries**: Structured output is supported; thinking, function calling and built-in tools are marked unsupported. [Source](https://www.alibabacloud.com/help/en/model-studio/text-generation-model) **Catalog qualifications:** The text-generation catalog labels this as legacy/no longer recommended; no API shutdown is asserted. [Source](https://www.alibabacloud.com/help/en/model-studio/text-generation-model) **Evidence still missing here:** complete input/output pricing and knowledge and training-data cutoffs. Missing documentation is not evidence that a feature is unavailable. Headless Thrones has not independently benchmarked this model for this reference. Evaluate it on representative work before choosing it; these facts do not rank its accuracy, reliability, speed or suitability against another model. Keep the exact version in view ## Other Qwen models from Qwen. These are separate records in the same publisher family. A shared family name does not establish equal capabilities or interchangeable licenses. ### [Qwen-1\_8B](https://headlessthrones.com/models/alibaba-qwen-qwen-1-8b) Open weights ### [Qwen-1\_8B-Chat-Int4](https://headlessthrones.com/models/alibaba-qwen-qwen-1-8b-chat-int4) Open weights ### [Qwen-1\_8B-Chat-Int8](https://headlessthrones.com/models/alibaba-qwen-qwen-1-8b-chat-int8) Open weights ### [Qwen-14B](https://headlessthrones.com/models/alibaba-qwen-qwen-14b) Open weights ### [Qwen-14B-Chat](https://headlessthrones.com/models/alibaba-qwen-qwen-14b-chat) Open weights ### [Qwen-72B](https://headlessthrones.com/models/alibaba-qwen-qwen-72b) Open weights
