Qwen3.5-Plus is a commercial Qwen3.5 model provided by Alibaba Cloud Model Studio. It supports text, image, and video input and produces text output. The model provides a 1 million token context window, 64K maximum output, function calling, built-in tools, and structured output.[1] It uses a hybrid thinking mode, with thinking enabled by default, and allows switching between thinking and non-thinking responses per request.[2]
Model Positioning and Core Capabilities
Qwen3.5-Plus combines long context, multimodal understanding, reasoning, and tool calling in a single model. Alibaba Cloud's model table lists it as a commercial model in the Qwen3.5 Plus series and provides the fixed snapshot qwen3.5-plus-2026-02-15.[1][2]
The model can call functions based on image or video content and can also use built-in tools such as web search and code execution. In non-thinking mode, it supports structured results that conform to the JSON specification.[1]
Capabilities and Specifications
Qwen3.5-Plus accepts text, images, and video and returns text. Its context window is 1 million tokens, and the maximum output per request is 64K tokens. A single request can include up to 256 images and 64 videos. Videos are limited to 2 hours or 2 GB.[1]
| Item | Specification |
|---|---|
| Input | Text, images, video [1] |
| Output | Text [1] |
| Context window | 1M tokens [1] |
| Maximum output | 64K tokens [1] |
| Images per request | Up to 256 [1] |
| Videos per request | Up to 64 [1] |
| Video limits | Up to 2 hours, up to 2 GB [1] |
| Tool capabilities | Function calling, web search, code execution [1] |
| Structured output | Supported in non-thinking mode [1] |
| Thinking mode | Hybrid thinking, enabled by default [2] |
Hybrid thinking is controlled through the enable_thinking parameter: when set to true, the model reasons before responding; when set to false, the model generates a response directly.[2]
Use Cases
Qwen3.5-Plus's multimodal input can be used for image analysis and video understanding.[1] Its 1 million token context can accommodate long documents or inputs composed of large amounts of material, while function calling, built-in tools, and structured output cover applications that require external actions or standardized results.[1]
Hybrid thinking allows the same model to switch between reasoning before answering and generating an answer directly.[2]
Important Limitations
The model outputs text only and does not generate images, video, or audio.[1] Structured output is limited to non-thinking mode. Image and video inputs are both subject to file count limits, while videos are also subject to duration and file size limits.[1]
Alibaba Cloud currently places Qwen3.5 in the legacy model group while continuing to list the full specifications for qwen3.5-plus and its fixed snapshot.[1]
