You can quantize your own models by installing AutoAWQ or picking one of the [6500+ models on Huggingface](https://huggingface.co/models?search=awq).
```console
```bash
pip install autoawq
```
After installing AutoAWQ, you are ready to quantize a model. Please refer to the [AutoAWQ documentation](https://casper-hansen.github.io/AutoAWQ/examples/#basic-quantization) for further details. Here is an example of how to quantize `mistralai/Mistral-7B-Instruct-v0.2`:
```python
from awq import AutoAWQForCausalLM
from transformers import AutoTokenizer
??? Code
model_path = 'mistralai/Mistral-7B-Instruct-v0.2'
quant_path = 'mistral-instruct-v0.2-awq'
quant_config = { "zero_point": True, "q_group_size": 128, "w_bit": 4, "version": "GEMM" }
```python
from awq import AutoAWQForCausalLM
from transformers import AutoTokenizer
# Load model
model = AutoAWQForCausalLM.from_pretrained(
model_path, **{"low_cpu_mem_usage": True, "use_cache": False}

from llmcompressor.modifiers.quantization import GPTQModifier
from llmcompressor.modifiers.smoothquant import SmoothQuantModifier
# Configure the quantization algorithms
recipe = [

SAVE_DIR = MODEL_ID.split("/")[1] + "-W8A8-Dynamic-Per-Token"
model.save_pretrained(SAVE_DIR, save_compressed=True)
tokenizer.save_pretrained(SAVE_DIR)

Remember to check whether the `reasoning_content` exists in the response before accessing it. You could checkout the [example](https://github.com/vllm-project/vllm/blob/main/examples/online_serving/openai_chat_completion_with_reasoning_streaming.py).
## Structured output
The reasoning content is also available in the structured output. The structured output engine like `xgrammar` will use the reasoning content to generate structured output. It is only supported in v0 engine now.
```bash
vllm serve deepseek-ai/DeepSeek-R1-Distill-Qwen-1.5B --reasoning-parser deepseek_r1
```
The following is an example client:
```python
from openai import OpenAI
from pydantic import BaseModel
# Modify OpenAI's API key and API base to use vLLM's API server.
openai_api_key = "EMPTY"
openai_api_base = "http://localhost:8000/v1"
client = OpenAI(
api_key=openai_api_key,
base_url=openai_api_base,
)
models = client.models.list()
model = models.data[0].id
class People(BaseModel):
name: str
age: int
json_schema = People.model_json_schema()
prompt = ("Generate a JSON with the name and age of one random person.")
completion = client.chat.completions.create(
model=model,
messages=[{
"role": "user",
"content": prompt,
}],
extra_body={"guided_json": json_schema},
)
print("reasoning_content: ", completion.choices[0].message.reasoning_content)
print("content: ", completion.choices[0].message.content)
```
## Tool Calling
The reasoning content is also available when both tool calling and the reasoning parser are enabled. Additionally, tool calling only parses functions from the `content` field, not from the `reasoning_content`.

!!! tip
While not strictly necessary, normally it´s better to indicate in the prompt the
JSON schema and how the fields should be populated. This can improve the
JSON schema and how the fields should be populated. This can improve the
results notably in most cases.
Finally we have the `guided_grammar` option, which is probably the most
difficult to use, but it´s really powerful. It allows us to define complete
languages like SQL queries. It works by using a context free EBNF grammar.

When tool_choice='required' is set, the model is guaranteed to generate one or more tool calls based on the specified tool list in the `tools` parameter. The number of tool calls depends on the user's query. The output format strictly follows the schema defined in the `tools` parameter.
## None Function Calling
vLLM supports the `tool_choice='none'` option in the chat completion API. When this option is set, the model will not generate any tool calls and will respond with regular text content only, even if tools are defined in the request.
By default, when `tool_choice='none'` is specified, vLLM excludes tool definitions from the prompt to optimize context usage. To include tool definitions even with `tool_choice='none'`, use the `--expand-tools-even-if-tool-choice-none` option.
Note: This behavior will change in v0.10.0, where tool definitions will be included by default even with `tool_choice='none'`.

### xLAM Models (`xlam`)
The xLAM tool parser is designed to support models that generate tool calls in various JSON formats. It detects function calls in several different output styles:
1. Direct JSON arrays: Output strings that are JSON arrays starting with `[` and ending with `]`
2. Thinking tags: Using `<think>...</think>` tags containing JSON arrays
3. Code blocks: JSON in code blocks (```json ...```)
4. Tool calls tags: Using `[TOOL_CALLS]` or `<tool_call>...</tool_call>` tags
Parallel function calls are supported, and the parser can effectively separate text content from tool calls.
Supported models:
* Salesforce Llama-xLAM models: `Salesforce/Llama-xLAM-2-8B-fc-r`, `Salesforce/Llama-xLAM-2-70B-fc-r`
