This example code shows how to call Qwen 3 Next 80B A3B Thinking using the openAI client. You can also make requests to the /predict endpoint with a message or /v1/completions endpoint with a prompt.
Qwen3-Next-80B-A3B-Thinking supports only thinking mode. To enforce model thinking, the default chat template automatically includes <think>. Therefore, it is normal for the model's output to contain only </think> without an explicit opening <think> tag.
Qwen3-Next-80B-A3B-Thinking may generate thinking content longer than its predecessor. We strongly recommend its use in highly complex reasoning tasks.
