Quickstart
For text generation, use a recent SGLang build with Qwen3.5 support. The checkpoint includes its tokenizer and MiMo v2.6 chat template.
sglang serve \ --model-path XiaomiMiMo/MiMo-V2.6-Distill-Qwen-9B \ --reasoning-parser mimo \ --host 0.0.0.0 \ --port 30000
Query the endpoint with thinking explicitly enabled:
from openai import OpenAI client = OpenAI( base_url="http://localhost:30000/v1", api_key="EMPTY",) response = client.chat.completions.create( model="XiaomiMiMo/MiMo-V2.6-Distill-Qwen-9B", messages=[ {"role": "user", "content": "What is 15% of 240?"} ], max_tokens=2048, extra_body={"chat_template_kwargs": {"enable_thinking": True}},) message = response.choices[0].messageprint("Thinking:", getattr(message, "reasoning_content", "") or "")print("Answer:", message.content or "")
