Qwen2.5-Coder-7B-Instruct

Qwen2.5-Coder-7B-Instruct

Writes, explains and fixes code as a 7B instruction-tuned member of the Qwen2.5-Coder family. For developers who want a capable open coding model that fits on a single consumer GPU.

Made by Qwen on Hugging Face. These notes are Mindket's, written from its model page and model card; the model's own files and license are on Hugging Face.

About

What it is: Qwen2.5-Coder-7B-Instruct is the 7B instruction-tuned model of the Qwen2.5-Coder series, formerly called CodeQwen. It is built for code generation, code reasoning and code fixing. The series comes in six sizes, from 0.5 to 32 billion parameters.

Who it suits: Developers who want an open coding model of moderate size, to run locally or inside their own tools.

Industry | Who uses it | How they use it | Example
Software | Developers | Generate and fix code with a local model | Ask for a quick sort routine
Dev tooling | Tool builders | Back a code assistant with an open model | Add code completion to an editor plugin
Education | Learners | Get code explained step by step | Ask why a loop never ends

If you need the strongest results the series offers, its 32B sibling is the larger option.

Where to use it:

• Your own computer with Python and the transformers library, on Windows, macOS or Linux
• vLLM, which the card recommends for deployment
• Qwen Chat, the hosted chat the card links

Use case | Who | What they get back
Code generation | Developers | Code written from a plain request
Code fixing | Developers | A corrected version of broken code
Code agents | Tool builders | A model that can sit inside agent workflows

How to set it up:

• Python with pip
• A recent transformers release, since versions below 4.37.0 fail with a KeyError for qwen2
• About 15.2 GB of disk space for the BF16 weights, or about 3.8 GB at 4-bit (an estimate)

1. Install the Hugging Face hub tool.
2. Download the model files.
3. Run the card's Python snippet, which loads the tokenizer and model and generates a reply.

pip install -U huggingface_hub
hf download Qwen/Qwen2.5-Coder-7B-Instruct

How to use it: Format a system and a user message with the chat template, then generate. The card's snippet below asks for a quick sort algorithm.

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "Qwen/Qwen2.5-Coder-7B-Instruct"

model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype="auto",
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained(model_name)

prompt = "write a quick sort algorithm."
messages = [
    {"role": "system", "content": "You are Qwen, created by Alibaba Cloud. You are a helpful assistant."},
    {"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)

generated_ids = model.generate(
    **model_inputs,
    max_new_tokens=512
)
generated_ids = [
    output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
]

response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]

For inputs longer than 32,768 tokens, the card says to add a YaRN setting to config.json, for frameworks that support it.

{
  ...,
  "rope_scaling": {
    "factor": 4.0,
    "original_max_position_embeddings": 32768,
    "type": "yarn"
  }
}

Example: You run the snippet as it is, which asks the model to write a quick sort algorithm. The variable response holds the model's code answer, up to 512 new tokens.

For newcomers and experts: If you are new, run the snippet above and swap the prompt for a small coding task of your own. A 7B model is a gentle first step before the larger sizes.

For experts, the model has 28 layers with 28 query heads and 4 key-value heads. The default config covers 32,768 tokens, and YaRN stretches it toward the full 131,072. The card says vLLM applies static YaRN, which may hurt shorter texts.

You send a coding request
The chat template formats the messages
The model generates code and explanation
You decode the reply and review it

Good to know: The card says the YaRN setting should only be added when you need long inputs.

• License: Apache 2.0, as the Hugging Face record lists it.
• Cost to run: no API key or account is named. You need hardware that can hold the weights.
• Data it reaches: downloading reaches Hugging Face. The snippet does not describe reaching other files or the web.
• Not for: the card names no banned uses. Static YaRN may lower quality on short texts, so enable it only for long inputs.

Get the model

Download its files with Hugging Face's command line:

pip install -U huggingface_hub
hf download Qwen/Qwen2.5-Coder-7B-Instruct

Then follow the usage in its model card. Nothing in this kit runs by itself.
