Qwen2.5-Coder-14B-Instruct is a large language model in the Qwen2.5-Coder series, focusing on code generation, reasoning, and repair. Built upon the powerful Qwen2.5, this model is trained on 5.5 trillion tokens, including source code and synthesized data, making it a leading open-source code LLM. It not only enhances coding capabilities but also maintains strengths in mathematics and general abilities while supporting long contexts of up to 128K tokens.
