+# Qwen 2.5 Coder 7B - llamafile
+
+- Model creator: [Qwen](https://huggingface.co/Qwen/)
+- Original model: [Qwen/Qwen2.5-Coder-7B-Instruct](https://huggingface.co/Qwen/Qwen2.5-Coder-7B-Instruct)
+
+Mozilla packaged the Qwen 2.5 Coder models into executable weights that we
+call [llamafiles](https://github.com/Mozilla-Ocho/llamafile). This gives
+you the easiest fastest way to use the model on Linux, MacOS, Windows,
+FreeBSD, OpenBSD and NetBSD systems you control on both AMD64 and ARM64.
+
+*Software Last Updated: 2025-03-31*
+
+*Llamafile Version: 0.9.2*
+
+## Quickstart
+
+To get started, you need both the Qwen 2.5 Coder weights, and the llamafile
+software. Both of them are included in a single file, which can be
+downloaded and run as follows:
+
+```
+wget https://huggingface.co/Mozilla/Qwen2.5.1-Coder-7B-Instruct-llamafile/resolve/main/Qwen2.5.1-Coder-7B-Instruct-Q6_K.llamafile
+chmod +x Qwen2.5.1-Coder-7B-Instruct-Q6_K.llamafile
+./Qwen2.5.1-Coder-7B-Instruct-Q6_K.llamafile
+```
+
+The default mode of operation for these llamafiles is our new command
+line chatbot interface.
+
+## Usage
+
+You can use triple quotes to ask questions on multiple lines. You can
+pass commands like `/stats` and `/context` to see runtime status
+information. You can change the system prompt by passing the `-p "new
+system prompt"` flag. You can press CTRL-C to interrupt the model.
+Finally CTRL-D may be used to exit.
+
+If you prefer to use a web GUI, then a `--server` mode is provided, that
+will open a tab with a chatbot and completion interface in your browser.
+For additional help on how it may be used, pass the `--help` flag. The
+server also has an OpenAI API compatible completions endpoint that can
+be accessed via Python using the `openai` pip package.
+
+```
+.Qwen2.5.1-Coder-7B-Instruct-Q6_K.llamafile --server
+```
+
+An advanced CLI mode is provided that's useful for shell scripting. You
+can use it by passing the `--cli` flag. For additional help on how it
+may be used, pass the `--help` flag.
+
+```
+./Qwen2.5.1-Coder-7B-Instruct-Q6_K.llamafile --cli -p 'four score and seven' --log-disable
+```
+
+## Troubleshooting
+
+Having **trouble?** See the ["Gotchas"
+section](https://github.com/mozilla-ocho/llamafile/?tab=readme-ov-file#gotchas-and-troubleshooting)
+of the README.
+
+On Linux, the way to avoid run-detector errors is to install the APE
+interpreter.
+
+```sh
+sudo wget -O /usr/bin/ape https://cosmo.zip/pub/cosmos/bin/ape-$(uname -m).elf
+sudo chmod +x /usr/bin/ape
+sudo sh -c "echo ':APE:M::MZqFpD::/usr/bin/ape:' >/proc/sys/fs/binfmt_misc/register"
+sudo sh -c "echo ':APE-jart:M::jartsr::/usr/bin/ape:' >/proc/sys/fs/binfmt_misc/register"
+```
+
+On Windows there's a 4GB limit on executable sizes.
+
+## Context Window
+
+This model has a max context window size of 128k tokens. By default, a
+context window size of 8192 tokens is used. You can ask llamafile 
+to use the maximum context size by passing the `-c 0` flag. That's big 
+enough for a small book. If you want to be able to have a conversation
+with your book, you can use the `-f book.txt` flag.
+
+## GPU Acceleration
+
+On GPUs with sufficient RAM, the `-ngl 999` flag may be passed to use
+the system's NVIDIA or AMD GPU(s). On Windows, only the graphics card
+driver needs to be installed if you own an NVIDIA GPU. On Windows, if
+you have an AMD GPU, you should install the ROCm SDK v6.1 and then pass
+the flags `--recompile --gpu amd` the first time you run your llamafile.
+
+On NVIDIA GPUs, by default, the prebuilt tinyBLAS library is used to
+perform matrix multiplications. This is open source software, but it
+doesn't go as fast as closed source cuBLAS. If you have the CUDA SDK
+installed on your system, then you can pass the `--recompile` flag to
+build a GGML CUDA library just for your system that uses cuBLAS. This
+ensures you get maximum performance.
+
+For further information, please see the [llamafile
+README](https://github.com/mozilla-ocho/llamafile/).
+
+## About llamafile
+
+llamafile is a new format introduced by Mozilla on Nov 20th 2023. It
+uses Cosmopolitan Libc to turn LLM weights into runnable llama.cpp
+binaries that run on the stock installs of six OSes for both ARM64 and
+AMD64.

+
+## Introduction
+
+Qwen2.5-Coder is the latest series of Code-Specific Qwen large language models (formerly known as CodeQwen). As of now, Qwen2.5-Coder has covered six mainstream model sizes, 0.5, 1.5, 3, 7, 14, 32 billion parameters, to meet the needs of different developers. Qwen2.5-Coder brings the following improvements upon CodeQwen1.5:
+
+- Significantly improvements in **code generation**, **code reasoning** and **code fixing**. Base on the strong Qwen2.5, we scale up the training tokens into 5.5 trillion including source code, text-code grounding, Synthetic data, etc. Qwen2.5-Coder-32B has become the current state-of-the-art open-source codeLLM, with its coding abilities matching those of GPT-4o.
+- A more comprehensive foundation for real-world applications such as **Code Agents**. Not only enhancing coding capabilities but also maintaining its strengths in mathematics and general competencies.
+- **Long-context Support** up to 128K tokens.
+
+**This repo contains the instruction-tuned 7B Qwen2.5-Coder model**, which has the following features:
+- Type: Causal Language Models
+- Training Stage: Pretraining & Post-training
+- Architecture: transformers with RoPE, SwiGLU, RMSNorm, and Attention QKV bias
+- Number of Parameters: 7.61B
+- Number of Paramaters (Non-Embedding): 6.53B
+- Number of Layers: 28
+- Number of Attention Heads (GQA): 28 for Q and 4 for KV
+- Context Length: Full 131,072 tokens
+  - Please refer to [this section](#processing-long-texts) for detailed instructions on how to deploy Qwen2.5 for handling long texts.
+  
+For more details, please refer to our [blog](https://qwenlm.github.io/blog/qwen2.5-coder-family/), [GitHub](https://github.com/QwenLM/Qwen2.5-Coder), [Documentation](https://qwen.readthedocs.io/en/latest/), [Arxiv](https://arxiv.org/abs/2409.12186).
+
+## Requirements
+
+The code of Qwen2.5-Coder has been in the latest Hugging face `transformers` and we advise you to use the latest version of `transformers`.
+
+With `transformers<4.37.0`, you will encounter the following error:
+```
+KeyError: 'qwen2'
+```
+
+## Quickstart
+
+Here provides a code snippet with `apply_chat_template` to show you how to load the tokenizer and model and how to generate contents.
+
+```python
+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]
+```
+
+### Processing Long Texts
+
+The current `config.json` is set for context length up to 32,768 tokens.
+To handle extensive inputs exceeding 32,768 tokens, we utilize [YaRN](https://arxiv.org/abs/2309.00071), a technique for enhancing model length extrapolation, ensuring optimal performance on lengthy texts.
+
+For supported frameworks, you could add the following to `config.json` to enable YaRN:
+```json
+{
+  ...,
+  "rope_scaling": {
+    "factor": 4.0,
+    "original_max_position_embeddings": 32768,
+    "type": "yarn"
+  }
+}
+```
+
+For deployment, we recommend using vLLM. 
+Please refer to our [Documentation](https://qwen.readthedocs.io/en/latest/deployment/vllm.html) for usage if you are not familar with vLLM.
+Presently, vLLM only supports static YARN, which means the scaling factor remains constant regardless of input length, **potentially impacting performance on shorter texts**. 
+We advise adding the `rope_scaling` configuration only when processing long contexts is required.
+
+## Evaluation & Performance
+
+Detailed evaluation results are reported in this [📑 blog](https://qwenlm.github.io/blog/qwen2.5-coder-family/).
+
+For requirements on GPU memory and the respective throughput, see results [here](https://qwen.readthedocs.io/en/latest/benchmark/speed_benchmark.html).
