About this model

deepseek-coder-1.3b-instruct is the smallest instruction-tuned checkpoint in the DeepSeek Coder family. The base models were trained from scratch on 2 trillion tokens, 87 percent code and 13 percent natural language in English and Chinese, using a fill-in-the-middle objective and a 16k context window for repository-level understanding. The instruct version is fine-tuned on coding instruction data so it follows requests like writing a function or explaining a snippet. Despite its size it scores well on HumanEval and MBPP relative to other sub-2B code models.
