使用方式

CLI

ollama run codellama "Write me a function that outputs the fibonacci sequence"

API

curl -X POST https://127.0.0.1:11434/api/generate -d '{
  "model": "codellama",
  "prompt": "Write me a function that outputs the fibonacci sequence"
}'

變體版本


`instruct`	經過微調，以自然語言生成有幫助且安全的答案
`python`	Code Llama 的一個特殊變體版本，在 1000 億個 Python 程式碼 tokens 上進一步微調
`code`	用於程式碼完成的基礎模型

範例提示

詢問問題

ollama run codellama:7b-instruct 'You are an expert programmer that writes simple, concise code and explanations. Write a python function to generate the nth fibonacci number.'

填空中間 (FIM) 或填充

ollama run codellama:7b-code '<PRE> def compute_gcd(x, y): <SUF>return result <MID>'

填空中間 (FIM) 是程式碼完成模型支援的一種特殊提示格式，可以完成兩個已編寫程式碼區塊之間的程式碼。Code Llama 期望填充程式碼使用特定格式

<PRE> {prefix} <SUF>{suffix} <MID>

<PRE>、<SUF> 和 <MID> 是引導模型的特殊 tokens。

程式碼審查

ollama run codellama '
Where is the bug in this code?

def fib(n):
    if n <= 0:
        return n
    else:
        return fib(n-1) + fib(n-2)
'

編寫測試

ollama run codellama "write a unit test for this function: $(cat example.py)"

程式碼完成

ollama run codellama:7b-code '# A simple python function to remove whitespace from a string:'

更多資訊

Code Llama is a model for generating and discussing code, built on top of [Llama 2](https://ollama.dev.org.tw/library/llama2). It's designed to make workflows faster and efficient for developers and make it easier for people to learn how to code. It can generate both code and natural language about code. Code Llama supports many of the most popular programming languages used today, including Python, C++, Java, PHP, Typescript (Javascript), C#, Bash and more.

| --------------- | ------------------------------ | -------------------------- |
| 7 billion       | [View](/library/codellama:7b)  | `ollama run codellama:7b`  |
| 13 billion      | [View](/library/codellama:13b) | `ollama run codellama:13b` |

## Usage

### CLI

```
ollama run codellama "Write me a function that outputs the fibonacci sequence"
```

### API

```
curl -X POST https://127.0.0.1:11434/api/generate -d '{
  "model": "codellama",
  "prompt": "Write me a function that outputs the fibonacci sequence"
}'
```

## Variations

|            |                                                                                        |
| ---------- | -------------------------------------------------------------------------------------- |
| `instruct` | Fine-tuned to generate helpful and safe answers in natural language                    |
| `python`   | A specialized variation of Code Llama further fine-tuned on 100B tokens of Python code |
| `code`     | Base model for code completion                                                         |

## Example prompts

### Ask questions

```
ollama run codellama:7b-instruct 'You are an expert programmer that writes simple, concise code and explanations. Write a python function to generate the nth fibonacci number.'
```

### Fill-in-the-middle (FIM) or infill

```
ollama run codellama:7b-code '<PRE> def compute_gcd(x, y): <SUF>return result <MID>'
```

Fill-in-the-middle (FIM) is a special prompt format supported by the code completion model can complete code between two already written code blocks. Code Llama expects a specific format for infilling code:

```
<PRE> {prefix} <SUF>{suffix} <MID>
```

`<PRE>`, `<SUF>` and `<MID>` are special tokens that guide the model.

### Code review

```
ollama run codellama '
Where is the bug in this code?

def fib(n):
    if n <= 0:
        return n
    else:
        return fib(n-1) + fib(n-2)
'
```

### Writing tests

```
ollama run codellama "write a unit test for this function: $(cat example.py)"
```

### Code completion

```
ollama run codellama:7b-code '# A simple python function to remove whitespace from a string:'
```
