Codellama
CodeLlama is a family of large language models derived from the Llama 2 architecture and specialized for producing, completing, and refactoring source code across multiple programming languages. It functions as a code generation model capable of synthesizing source code from natural language descriptions.
The project includes specific model variants designed for different programming tasks. This includes instruction-tuned models trained to follow complex natural language directions and code infilling models that predict and insert missing code segments into existing files by analyzing surrounding context.
The models support wide-ranging capabilities including predictive code completion, automated code generation, and large-scale code analysis. These functions are enabled through training methods such as fill-in-the-middle training and the extension of the context window to process larger amounts of input text.
