- ## Switching Between Thinking and Non-Thinking Mode
165
 
166
- > [!TIP]
167
- > The `enable_thinking` switch is also available in APIs created by SGLang and vLLM.
168
- > Please refer to our documentation for [SGLang](https://qwen.readthedocs.io/en/latest/deployment/sglang.html#thinking-non-thinking-modes) and [vLLM](https://qwen.readthedocs.io/en/latest/deployment/vllm.html#thinking-non-thinking-modes) users.
169
-
170
- ### `enable_thinking=True`
171
 
172
- By default, Qwen3 has thinking capabilities enabled, similar to QwQ-32B. This means the model will use its reasoning abilities to enhance the quality of generated responses. For example, when explicitly setting `enable_thinking=True` or leaving it as the default value in `tokenizer.apply_chat_template`, the model will engage its thinking mode.
173
 
174
- ```python
175
- text = tokenizer.apply_chat_template(
176
- messages,
177
- tokenize=False,
178
- add_generation_prompt=True,
179
- enable_thinking=True # True is the default value for enable_thinking
180
- )
181
  ```
182
 
183
- In this mode, the model will generate think content wrapped in a `<think>...</think>` block, followed by the final response.
184
 
185
- > [!NOTE]
186
- > For thinking mode, use `Temperature=0.6`, `TopP=0.95`, `TopK=20`, and `MinP=0` (the default setting in `generation_config.json`). **DO NOT use greedy decoding**, as it can lead to performance degradation and endless repetitions. For more detailed guidance, please refer to the [Best Practices](#best-practices) section.
187
 
 
188
 
189
- ### `enable_thinking=False`
190
 
191
- We provide a hard switch to strictly disable the model's thinking behavior, aligning its functionality with the previous Qwen2.5-Instruct models. This mode is particularly useful in scenarios where disabling thinking is essential for enhancing efficiency.
192
 
193
  ```python
194
  text = tokenizer.apply_chat_template(
195
  messages,
196
  tokenize=False,
197
  add_generation_prompt=True,
198
- enable_thinking=False # Setting enable_thinking=False disables thinking mode
199
  )
200
  ```
201
 
202
- In this mode, the model will not generate any think content and will not include a `<think>...</think>` block.
203
 
204
- > [!NOTE]
205
- > For non-thinking mode, we suggest using `Temperature=0.7`, `TopP=0.8`, `TopK=20`, and `MinP=0`. For more detailed guidance, please refer to the [Best Practices](#best-practices) section.
206
 
207
- ### Advanced Usage: Switching Between Thinking and Non-Thinking Modes via User Input
208
 
209
- We provide a soft switch mechanism that allows users to dynamically control the model's behavior when `enable_thinking=True`. Specifically, you can add `/think` and `/no_think` to user prompts or system messages to switch the model's thinking mode from turn to turn. The model will follow the most recent instruction in multi-turn conversations.
210
 
211
- Here is an example of a multi-turn conversation:
212
-
213
- ```python
214
- from transformers import AutoModelForCausalLM, AutoTokenizer
215
-
216
- class QwenChatbot:
217
- def __init__(self, model_name="Qwen/Qwen3-235B-A22B"):

255
- response_2 = chatbot.generate_response(user_input_2)
256
- print(f"Bot: {response_2}")
257
- print("----------------------")
258
-
259
- # Third input with /think
260
- user_input_3 = "Really? /think"
261
- print(f"User: {user_input_3}")
262
- response_3 = chatbot.generate_response(user_input_3)
263
- print(f"Bot: {response_3}")
264
- ```
265
-
266
- > [!NOTE]
267
- > For API compatibility, when `enable_thinking=True`, regardless of whether the user uses `/think` or `/no_think`, the model will always output a block wrapped in `<think>...</think>`. However, the content inside this block may be empty if thinking is disabled.
268
- > When `enable_thinking=False`, the soft switches are not valid. Regardless of any `/think` or `/no_think` tags input by the user, the model will not generate think content and will not include a `<think>...</think>` block.

270
  ## Agentic Use
271
 
272
- Qwen3 excels in tool calling capabilities. We recommend using [Qwen-Agent](https://github.com/QwenLM/Qwen-Agent) to make the best use of agentic ability of Qwen3. Qwen-Agent encapsulates tool-calling templates and tool-calling parsers internally, greatly reducing coding complexity.
273
 
274
- To define the available tools, you can use the MCP configuration file, use the integrated tool of Qwen-Agent, or integrate other tools by yourself.

  ## Processing Long Texts
325
 
326
- Qwen3 natively supports context lengths of up to 32,768 tokens. For conversations where the total length (including both input and output) significantly exceeds this limit, we recommend using RoPE scaling techniques to handle long texts effectively. We have validated the model's performance on context lengths of up to 131,072 tokens using the [YaRN](https://arxiv.org/abs/2309.00071) method.
327
-
328
- YaRN is currently supported by several inference frameworks, e.g., `transformers` and `llama.cpp` for local use, `vllm` and `sglang` for deployment. In general, there are two approaches to enabling YaRN for supported frameworks:
329
-
330
- - Modifying the model files:
331
- In the `config.json` file, add the `rope_scaling` fields:
332
- ```json
333
- {
334
- ...,
335
- "rope_scaling": {
336
- "rope_type": "yarn",
337
- "factor": 4.0,
338
- "original_max_position_embeddings": 32768
339
- }
340
- }
341
- ```
342
- For `llama.cpp`, you need to regenerate the GGUF file after the modification.
343
-
344
- - Passing command line arguments:
345
-
346
- For `vllm`, you can use
347
- ```shell
348
- vllm serve ... --rope-scaling '{"rope_type":"yarn","factor":4.0,"original_max_position_embeddings":32768}' --max-model-len 131072
349
- ```
350
-
351
- For `sglang`, you can use
352
- ```shell
353
- python -m sglang.launch_server ... --json-model-override-args '{"rope_scaling":{"rope_type":"yarn","factor":4.0,"original_max_position_embeddings":32768}}'
354
- ```
355
-
356
- For `llama-server` from `llama.cpp`, you can use
357
- ```shell
358
- llama-server ... --rope-scaling yarn --rope-scale 4 --yarn-orig-ctx 32768
359
- ```
360
-
361
- > [!IMPORTANT]
362
- > If you encounter the following warning
363
- > ```
364
- > Unrecognized keys in `rope_scaling` for 'rope_type'='yarn': {'original_max_position_embeddings'}
365
- > ```
366
- > please upgrade `transformers>=4.51.0`.
367
-
368
- > [!NOTE]
369
- > All the notable open-source frameworks implement static YaRN, which means the scaling factor remains constant regardless of input length, **potentially impacting performance on shorter texts.**
370
- > We advise adding the `rope_scaling` configuration only when processing long contexts is required.
371
- > It is also recommended to modify the `factor` as needed. For example, if the typical context length for your application is 65,536 tokens, it would be better to set `factor` as 2.0.
372
-
373
- > [!NOTE]
374
- > The default `max_position_embeddings` in `config.json` is set to 40,960. This allocation includes reserving 32,768 tokens for outputs and 8,192 tokens for typical prompts, which is sufficient for most scenarios involving short text processing. If the average context length does not exceed 32,768 tokens, we do not recommend enabling YaRN in this scenario, as it may potentially degrade model performance.
375
-
376
- > [!TIP]
377
- > The endpoint provided by Alibaba Model Studio supports dynamic YaRN by default and no extra configuration is needed.
378
 
379
- ## Best Practices
380
 
381
- To achieve optimal performance, we recommend the following settings:
382
 
383
- 1. **Sampling Parameters**:
384
- - For thinking mode (`enable_thinking=True`), use `Temperature=0.6`, `TopP=0.95`, `TopK=20`, and `MinP=0`. **DO NOT use greedy decoding**, as it can lead to performance degradation and endless repetitions.
385
- - For non-thinking mode (`enable_thinking=False`), we suggest using `Temperature=0.7`, `TopP=0.8`, `TopK=20`, and `MinP=0`.
386
- - For supported frameworks, you can adjust the `presence_penalty` parameter between 0 and 2 to reduce endless repetitions. However, using a higher value may occasionally result in language mixing and a slight decrease in model performance.
 
 
 
387
 
388
- 2. **Adequate Output Length**: We recommend using an output length of 32,768 tokens for most queries. For benchmarking on highly complex problems, such as those found in math and programming competitions, we suggest setting the max output length to 38,912 tokens. This provides the model with sufficient space to generate detailed and comprehensive responses, thereby enhancing its overall performance.
 
 
389
 
390
- 3. **Standardize Output Format**: We recommend using prompts to standardize model outputs when benchmarking.
391
- - **Math Problems**: Include "Please reason step by step, and put your final answer within \boxed{}." in the prompt.
392
- - **Multiple-Choice Questions**: Add the following JSON structure to the prompt to standardize responses: "Please show your choice in the `answer` field with only the choice letter, e.g., `"answer": "C"`."
393
 
394
- 4. **No Thinking Content in History**: In multi-turn conversations, the historical model output should only include the final output part and does not need to include the thinking content. It is implemented in the provided chat template in Jinja2. However, for frameworks that do not directly use the Jinja2 chat template, it is up to the developers to ensure that the best practice is followed.

96
 
97
+ ## Quickstart
98
+
99
+ > **Note:** Use `transformers>=4.51.0` to avoid `KeyError: 'qwen3_moe'`.
 
100
 
 
101
  ```python
102
  from transformers import AutoModelForCausalLM, AutoTokenizer
103
 
 
120
  messages,
121
  tokenize=False,
122
  add_generation_prompt=True,
123
+ enable_thinking=True # default True
124
  )
125
  model_inputs = tokenizer([text], return_tensors="pt").to(model.device)
126
 
 
129
  **model_inputs,
130
  max_new_tokens=32768
131
  )
132
+ output_ids = generated_ids[0][len(model_inputs.input_ids[0]):].tolist()
133
 
134
  # parsing thinking content
135
  try:
 
136
  index = len(output_ids) - output_ids[::-1].index(151668)
137
  except ValueError:
138
  index = 0
 
139
  thinking_content = tokenizer.decode(output_ids[:index], skip_special_tokens=True).strip("\n")
140
  content = tokenizer.decode(output_ids[index:], skip_special_tokens=True).strip("\n")
141
 
 
143
  print("content:", content)
144
  ```
145
 
146
+ ### Deployment
 
 
 
 
 
 
 
 
 
 
147
 
148
+ * **SGLang**:
149
 
150
+ ```shell
151
+ python -m sglang.launch_server --model-path Qwen/Qwen3-235B-A22B --reasoning-parser qwen3 --tp 8
152
+ ```
 
 
153
 
154
+ * **vLLM**:
155
 
156
+ ```shell
157
+ vllm serve Qwen/Qwen3-235B-A22B --enable-reasoning --reasoning-parser deepseek_r1
 
 
 
 
 
158
  ```
159
 
160
+ Local use supported by Ollama, LMStudio, MLX-LM, llama.cpp, and KTransformers.
161
 
162
+ ## Switching Between Thinking and Non-Thinking Modes
 
163
 
164
+ > **Tip:** Use `enable_thinking` in `tokenizer.apply_chat_template` or soft switches `/think` and `/no_think` in prompts.
165
 
166
+ ### `enable_thinking=True`
167
 
168
+ The model generates reasoning wrapped in `<think>...</think>` followed by the final response.
169
 
170
  ```python
171
  text = tokenizer.apply_chat_template(
172
  messages,
173
  tokenize=False,
174
  add_generation_prompt=True,
175
+ enable_thinking=True
176
  )
177
  ```
178
 
179
+ > **Note:** For thinking mode, use `Temperature=0.6`, `TopP=0.95`, `TopK=20`, `MinP=0`. Do **not** use greedy decoding.
180
 
181
+ ### `enable_thinking=False`
 
182
 
183
+ No `<think>...</think>` blocks are produced. Recommended settings: `Temperature=0.7`, `TopP=0.8`, `TopK=20`, `MinP=0`.
184
 
185
+ ### Soft Switches
186
 
187
+ * Add `/think` or `/no_think` to include or omit reasoning in the same `enable_thinking=True` setting.
188
+ * Soft switches are ignored when `enable_thinking=False`.

190
  ## Agentic Use
191
 
192
+ Qwen3 excels in tool calling. Use [Qwen-Agent](https://github.com/QwenLM/Qwen-Agent) for streamlined integration.
193
 
 
194
  ```python
195
  from qwen_agent.agents import Assistant
196
 
 
197
  llm_cfg = {
198
  'model': 'Qwen3-235B-A22B',
199
+ 'model_server': 'http://localhost:8000/v1',
 
 
 
 
 
 
200
  'api_key': 'EMPTY',
 
 
 
 
 
 
 
201
  }
202
 
 
203
  tools = [
204
+ {'mcpServers': {
205
+ 'time': {'command': 'uvx', 'args': ['mcp-server-time', '--local-timezone=Asia/Shanghai']},
206
+ 'fetch': {'command': 'uvx', 'args': ['mcp-server-fetch']}
207
+ }},
208
+ 'code_interpreter',
 
 
 
 
 
 
 
209
  ]
210
 
 
211
  bot = Assistant(llm=llm_cfg, function_list=tools)
212
 
 
213
  messages = [{'role': 'user', 'content': 'https://qwenlm.github.io/blog/ Introduce the latest developments of Qwen'}]
214
  for responses in bot.run(messages=messages):
215
  pass
 
218
 
219
  ## Processing Long Texts
220
 
221
+ Qwen3 natively supports up to 32,768 tokens. For up to 131,072 tokens, use YaRN [ArXiv:2309.00071](https://arxiv.org/abs/2309.00071).
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
222
 
223
+ ### Enabling YaRN
224
 
225
+ * **Transformers config**:
226
 
227
+ ```json
228
+ {
229
+ "rope_scaling": {"rope_type": "yarn", "factor": 4.0, "original_max_position_embeddings": 32768}
230
+ }
231
+ ```
232
+
233
+ * **vLLM**:
234
 
235
+ ```shell
236
+ vllm serve ... --rope-scaling '{"rope_type":"yarn","factor":4.0,"original_max_position_embeddings":32768}' --max-model-len 131072
237
+ ```
238
 
239
+ * **llama.cpp**:
 
 
240
 
241
+ ```shell
242
+ llama-server ... --rope-scaling yarn --rope-scale 4 --yarn-orig-ctx 32768
243
+ ```
244
 
245
+ > **Important:** Upgrade to `transformers>=4.51.0` to avoid warnings about unrecognized keys in `rope_scaling`.
246
 
247
+ > **Tip:** Only enable YaRN when needed for long contexts; default 40,960 embeddings suffice for most scenarios.
248
 
249
+ ## Best Practices
250
+
251
+ 1. **Sampling Parameters**
252
+
253
+ * Thinking mode: `Temperature=0.6`, `TopP=0.95`, `TopK=20`, `MinP=0`.
254
+ * Non-thinking mode: `Temperature=0.7`, `TopP=0.8`, `TopK=20`, `MinP=0`.
255
+ 2. **Output Length**: 32,768 tokens usually enough; up to 38,912 for complex tasks.
256
+ 3. **Standardised Format**
257
+
258
+ * **Math**: Request step-by-step reasoning and final answer in `\boxed{}`.
259
+ * **MCQs**: Use JSON to specify answers, e.g., `"answer": "C"`.
260
+ 4. **History**: Exclude `<think>` blocks from conversation history.
