Starcoder is a large language model and associated framework designed to generate, complete, and evaluate source code across multiple programming languages. It functions as a source code model that can produce complete function implementations and predict subsequent characters in a line of code based on provided prompts.
The project provides a specialized toolkit for adapting base models to specific coding tasks and instruction-following behaviors. This includes a conversational code assistant framework for training models to generate code via natural language chat, as well as a parameter-efficient fine-tuning framework that uses adapter layers to minimize computational costs.
The system covers a broad range of capabilities including causal language modeling, multi-turn dialogue training, and data engineering for dialogue dataset formatting. It also includes a standardized evaluation harness to measure the accuracy and quality of generated code outputs through predefined test cases and benchmarks.
