CodeLLaMA-13B

Meta’s Mid-Sized Powerhouse for Programming

What is CodeLLaMA-13B?

CodeLLaMA-13B is a mid-sized, open-weight large language model from Meta AI, tailored for code generation, understanding, and completion. It builds on the strengths of the original LLaMA 2 architecture, trained with a strong focus on source code across multiple languages. With 13 billion parameters, it offers a performance-to-scale sweet spot—powerful enough for production use, yet lightweight enough for cost-effective deployment.

Featuring fill-in-the-middle (FIM) capabilities, instruction-tuned variants, and support for popular programming languages, CodeLLaMA-13B is ideal for developers, researchers, and enterprises looking to integrate advanced AI into software engineering workflows.
