## Highlights |
|
|
|
|
|
Today, we're announcing **Qwen3-Coder**, our most agentic code model to date. **Qwen3-Coder** is available in multiple sizes, but we're excited to introduce its most powerful variant first: **Qwen3-Coder-480B-A35B-Instruct**. featuring the following key enhancements: |
|
|
|
|
|
- **Significant Performance** among open models on **Agentic Coding**, **Agentic Browser-Use**, and other foundational coding tasks, achieving results comparable to Claude Sonnet. |
|
|
- **Long-context Capabilities** with native support for **256K** tokens, extendable up to **1M** tokens using Yarn, optimized for repository-scale understanding. |
|
|
- **Agentic Coding** supporting for most platforms such as **Qwen Code**, **CLINE**, featuring a specially designed function call format. |
|
|
|
|
|
 |
|
|
|
|
|
## Model Overview |
|
|
|
|
|
**Qwen3-480B-A35B-Instruct** has the following features: |
|
|
- Type: Causal Language Models |
|
|
- Training Stage: Pretraining & Post-training |
|
|
- Number of Parameters: 480B in total and 35B activated |
|
|
- Number of Layers: 62 |
|
|
- Number of Attention Heads (GQA): 96 for Q and 8 for KV |
|
|
- Number of Experts: 160 |
|
|
- Number of Activated Experts: 8 |
|
|
- Context Length: **262,144 natively**. |
|
|
|
|
|
**NOTE: This model supports only non-thinking mode and does not generate ``<think></think>`` blocks in its output. Meanwhile, specifying `enable_thinking=False` is no longer required.** |
|
|
|
|

For more details, including benchmark evaluation, hardware requirements, and inference performance, please refer to our [blog](https://qwenlm.github.io/blog/qwen3-coder/), [GitHub](https://github.com/QwenLM/Qwen3-Coder), and [Documentation](https://qwen.readthedocs.io/en/latest/). |
|
|
|
|
|
|
|
|
## Quickstart |
|
|
|
|
|
We advise you to use the latest version of `transformers`. |
|
|
|
|
|
With `transformers<4.51.0`, you will encounter the following error: |
|
|
``` |
|
|
KeyError: 'qwen3_moe' |
|
|
``` |
|
|
|
|
|
The following contains a code snippet illustrating how to use the model generate content based on given inputs. |
|
|
```python |
|
|
from transformers import AutoModelForCausalLM, AutoTokenizer |
|
|
|
|
|
model_name = "Qwen/Qwen3-480B-A35B-Instruct" |
|
|
|
|
|
# load the tokenizer and the model |
|
|
tokenizer = AutoTokenizer.from_pretrained(model_name) |
|
|
model = AutoModelForCausalLM.from_pretrained( |
|
|
model_name, |
|
|
torch_dtype="auto", |
|
|
device_map="auto" |
|
|
) |
|
|
|
|
|
# prepare the model input |
|
|
prompt = "Write a quick sort algorithm." |
|
|
messages = [ |
|
|
{"role": "user", "content": prompt} |
|
|
] |
|
|
text = tokenizer.apply_chat_template( |
|
|
messages, |
|
|
tokenize=False, |
|
|
add_generation_prompt=True, |
|
|
) |
|
|
model_inputs = tokenizer([text], return_tensors="pt").to(model.device) |
|
|
|
|
|
# conduct text completion |
|
|
generated_ids = model.generate( |
|
|
**model_inputs, |
|
|
max_new_tokens=65536 |
|
|
) |
|
|
output_ids = generated_ids[0][len(model_inputs.input_ids[0]):].tolist() |
|
|
|
|
|
content = tokenizer.decode(output_ids, skip_special_tokens=True) |
|
|
|
|
|
print("content:", content) |
|
|
``` |
|
|
|
|
|
**Note: If you encounter out-of-memory (OOM) issues, consider reducing the context length to a shorter value, such as `32,768`.** |
|
|
|
|
|
For local use, applications such as Ollama, LMStudio, MLX-LM, llama.cpp, and KTransformers have also supported Qwen3. |
|
|
|
|
|
## Agentic Coding |
|
|
|
|
|
Qwen3-Coder excels in tool calling capabilities. |
|
|
|
|
|
You can simply define or use any tools as following example. |
|
|
```python |
|
|
# Your tool implementation |
|
|
def square_the_number(num: float) -> dict: |
|
|
return num ** 2 |
|
|
|
|
|
# Define Tools |
|
|
tools=[ |
|
|
{ |
|
|
"type":"function", |
|
|
"function":{ |
|
|
"name": "square_the_number", |
|
|
"description": "output the square of the number.", |
|
|
"parameters": { |
|
|
"type": "object", |
|
|
"required": ["input_num"], |
|
|
"properties": { |
|
|
'input_num': { |
|
|
'type': 'number', |
|
|
'description': 'input_num is a number that will be squared' |
|
|
} |
|
|
}, |
|
|
} |
|
|
} |
|
|
} |
|
|
] |
|
|
|
|
|
import OpenAI |
|
|
# Define LLM |
|
|
client = OpenAI( |
|
|
# Use a custom endpoint compatible with OpenAI API |
|
|
base_url='http://localhost:8000/v1', # api_base |
|
|
api_key="EMPTY" |
|
|
) |
|
|
|
|
|
messages = [{'role': 'user', 'content': 'square the number 1024'}] |
|
|
|
|
|
completion = client.chat.completions.create( |
|
|
messages=messages, |
|
|
model="Qwen3-480B-A35B-Instruct", |
|
|
max_tokens=65536, |
|
|
tools=tools, |
|
|
) |
|
|
|
|
|
print(completion.choice[0]) |
|
|
``` |
|
|
|
|
|
## Best Practices |
|
|
|
|
|
To achieve optimal performance, we recommend the following settings: |
|
|
|
|
|
1. **Sampling Parameters**: |
|
|
- We suggest using `temperature=0.7`, `top_p=0.8`, `top_k=20`, `repetition_penalty=1.05`. |
|
|
|
|
|
2. **Adequate Output Length**: We recommend using an output length of 65,536 tokens for most queries, which is adequate for instruct models. |
