Simon Willison reviews the Qwen2.5-Coder Series from Alibaba’s research team. The 32B model version is open-source and capable of running on a MacBook Pro M2, which Willison tested. His assessments based on both Qwen’s scores and Paul Gauthier’s Aider benchmarks suggest that Qwen2.5-Coder-32B is highly competitive, offering comparison with existing models such as GPT-4o and Claude 3.5. He also provides detailed insights into running different versions of the model on his Mac.
