Code Llama is a revolutionary new AI system from Meta focused on computer code understanding and generation. As a specialized version of the Llama language model, Code Llama is trained extensively on code and programming language data.

This massive code-centric training empowers Code Llama to generate code, explain code in natural language, and answer questions about code. Still in active development, Code Llama promises to transform how programmers build, document, and comprehend software. Its code comprehension abilities open new frontiers in AI assistants for developers.

How Does Code Llama Work

Code Llama utilizes a massive pretrained language model to generate code from natural language prompts. By training on huge datasets of real-world code and programming language documentation, the model learns the patterns and syntax of code.

When given a natural language description, Code Llama breaks down the input into key components. It searches its vast knowledge to find relevant code snippets that match those components. Code Llama combines and adapts appropriate code fragments to produce working code that aligns with the original description.

Code Llama can also comprehend and explain existing code. It analyzes the logic and functioning of code to provide natural language descriptions. Additionally, it can answer specific questions about how a given code snippet operates. Code Llama aims to augment both code generation and comprehension.
