About StarCoder2 3B

StarCoder2-3B is a 3-billion parameter large language model developed by the BigCode project, focusing on code generation tasks. Its architecture features a transformer decoder with grouped-query and sliding window attention, trained using the Fill-in-the-Middle objective. The model supports a context window of 16,384 tokens, allowing it to handle large contexts for tasks like code completion and translation across 17 programming languages. However, it is not designed for direct instruction-following.
