Code Model
A language model specifically trained or fine-tuned to understand and generate programming code.
Full Definition
Code models are trained on large corpora of source code across many programming languages, enabling them to write, complete, debug, explain, and translate code. They learn syntactic rules, common patterns, API conventions, and algorithmic idioms from billions of lines of open-source code. Models like GitHub Copilot (based on Codex), Code Llama, and DeepSeek Coder are purpose-built for coding tasks. General-purpose models like GPT-4 and Claude also perform strongly at code because their training data includes substantial code, but dedicated code models can outperform them on niche languages and tasks like low-level systems programming.
Examples
GitHub Copilot auto-completing a Python function body from a docstring describing the function's purpose.
Code Llama translating a C function to equivalent Rust with memory safety improvements.
