### 1. Introduction of DeepSeek Coder
|
||||
|
||||
Deepseek Coder comprises a series of code language models trained on both 87% code and 13% natural language in English and Chinese, with each model pre-trained on 2T tokens. We provide various sizes of the code model, ranging from 1B to 33B versions. Each model is pre-trained on project-level code corpus by employing a window size of 16K and a extra fill-in-the-blank task, to support project-level code completion and infilling. For coding capabilities, Deepseek Coder achieves state-of-the-art performance among open-source code models on multiple programming languages and various benchmarks.

|
||||
|
||||
#### Data Creation
|
||||
|
||||
- Step 1: Collecting code data from GitHub and apply the same filtering rules as [StarcoderData](https://github.com/bigcode-project/bigcode-dataset) to filter data.

|
||||
- Step 2: Parsing the dependencies of files within the same repository to rearrange the file positions based on their dependencies.
|
||||
- Step 3: Concatenating dependent files to form a single example and employ repo-level minhash for deduplication.
|
||||
- Step 4: Further filtering out low-quality code, such as codes with syntax errors or poor readability.

|

|
||||
- Step 1: Initially pre-trained with a dataset consisting of 87% code, 10% code-related language (Github Markdown and StackExchange), and 3% non-code related Chinese language. Models are pre-trained using 1.8T tokens and a 4K window size in this step.

|
||||
- Step 2: Further Pre-training using an extended 16K window size on an additional 200B tokens, resulting in foundational models (**DeepSeek-Coder-Base**).
|
||||
- Step 3: Instruction Fine-tuning on 2B tokens of instruction data, resulting in instruction-tuned models (**DeepSeek-Coder-Instruct**).

### 4. How to Use
|
||||
Here give some examples of how to use our model.
|
||||
#### 1）Code Completion
|
||||
Before proceeding, you'll need to install the necessary dependencies. You can do this by running the following command:
|
||||
```
|
||||
pip install -r requirements.txt
|
||||
```
|
||||
A demo is also available on the [🤗 Hugging Face Space](https://huggingface.co/spaces/deepseek-ai/deepseek-coder-33b-instruct), and you can run the demo locally using `app.py` in the [demo](https://github.com/deepseek-ai/deepseek-coder/tree/main/demo) folder. (Thanks to all the HF team for their support)

||||

||||
Here are some examples of how to use our model.

|

This code works by selecting a 'pivot' element from the array and partitioning the other elements into two sub-arrays, according to whether they are less than or greater than the pivot. The pivot element is then in its final position. The process is then repeated for the sub-arrays.
|
||||
```
|
||||
|
||||
#### 4）Repository Level Code Completion
|
||||
If you don't want to use the provided API `apply_chat_template` which loads the template from `tokenizer_config.json`, you can use the following template to chat with our model. Replace the `['content']` with your instructions and the model's previous (if any) responses, then the model will generate the response to the currently given instruction.

||||
