Code Llama is a model for generating and discussing code, built on top of Llama 2. 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.

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)"
