What is Code Llama?
Code Llama is a state-of-the-art large language model (LLM) designed specifically for generating code and natural language about code. It is built on top of Llama 2 and is available in three different models: Code Llama (foundational code model), Codel Llama - Python (specialized for Python), and Code Llama - Instruct (fine-tuned for understanding natural language instructions). Code Llama can generate code and natural language about code based on prompts from both code and natural language inputs. It can be used for tasks such as code completion and debugging in popular programming languages like Python, C++, Java, PHP, Typescript, C#, and Bash.Code Llama comes in different sizes with varying parameters, such as 7B, 13B, and 34B. These models have been trained on a large amount of code and code-related data. The 7B and 13B models have fill-in-the-middle capability, enabling them to support code completion tasks. The 34B model provides the best coding assistance but may have higher latency. The models can handle input sequences of up to 100,000 tokens, allowing for more context and relevance in code generation and debugging scenarios.Additionally, Code Llama has two fine-tuned variations: Code Llama - Python, which is specialized for Python code generation, and Code Llama - Instruct, which has been trained to provide helpful and safe answers in natural language. It is important to note that Code Llama is not suitable for general natural language tasks and should be used solely for code-specific tasks.Code Llama has been benchmarked against other open-source LLMs and has demonstrated superior performance, scoring high on coding benchmarks such as HumanEval and Mostly Basic Python Programming (MBPP). Responsible development and safety measures have been undertaken in the creation of Code Llama.Overall, Code Llama is a powerful and versatile tool that can enhance coding workflows, assist developers, and aid in learning and understanding code.

Code Llama FAQ
What is Code Llama?
Code Llama is a state-of-the-art large language model designed specifically for generating code and natural language about code. It is built on top of Llama 2, enhancing coding capabilities. It is available in three models: the foundational code model, a version specialized for Python, and one fine-tuned for understanding natural language instructions. The model can generate code given text prompts, aiding in tasks like code completion and debugging.
How does Code Llama generate code?
Code Llama generates code based on prompts from both code and natural language inputs. It utilizes its extensive language model, trained on a wealth of code and code-related information, to comprehend the provided prompt and produce relevant code in return. It's designed to insert code into existing code, making it suitable for tasks like code completion.
What are the three different models of Code Llama?
The three models of Code Llama are: Code Llama, the foundational code model, that generates code and natural language based on prompts from both code and natural language inputs; Code Llama - Python, which is specialized for Python code generation; and Code Llama - Instruct, which is fine-tuned for understanding natural language instructions, providing helpful and safe answers in natural language.
How is Code Llama specialized for Python?
The Code Llama - Python is specialized for Python by being further fine-tuned on 100B tokens of Python code. This fine-tuning allows it to generate Python code according to the most benchmarked language for code generation providing additional utility.
What is the key function of Code Llama - Instruct?
Code Llama - Instruct's key function is understanding natural language instructions. It's been trained with a different objective, providing it with a natural language instruction input and the expected output. This training makes it capable of better understanding what users want from their prompts.
How can Code Llama be used for code completion?
Code Llama supports code completion through its fill-in-the-middle capability. This enables it to insert new code into existing code, making it an ideal tool for code completion tasks. Based on the code and natural language prompts provided to it, Code Llama generates code that fills in the gaps.
What programming languages does Code Llama support?
Code Llama supports many popular programming languages in use today, including Python, C++, Java, PHP, Typescript (Javascript), C#, and Bash.
What is the relevance of 7B,13B, and 34B with Code Llama models?
The relevance of 7B, 13B, and 34B with the Code Llama models pertains to the varying parameters of different sizes in which Code Llama comes. These figures represent the number of parameters in the models. The higher the number, the more advanced the model with the 34B model offering the best coding assistance, but potentially with a higher latency.
