CodeQwen1.5 is an open-source large language model specialized in code, supporting 92 programming languages and long-context understanding.

CodeQwen1.5-7B is a specialized code LLM built upon the Qwen1.5 language model, pretrained with approximately 3 trillion tokens of code-related data. It supports 92 programming languages and offers long-context understanding and generation, processing up to 64K tokens. The model demonstrates capabilities in basic code generation, long-context modeling, code editing, and SQL. This open-source model aims to provide a transparent and accessible alternative to proprietary coding assistants, addressing concerns related to cost, privacy, security, and copyright. It has been evaluated on benchmarks like HumanEval, MBPP, LiveCodeBench, and SWE Bench, showing competitive performance against larger and proprietary models. CodeQwen1.5 is part of the Qwen1.5 open-source family and is intended to advance research in code assistance and code agents.
