Open-source Qwen model reaches top-tier AI capability levels

Alibaba's Qwen3.8-27B open model scored at performance levels matching DeepSeek V4-Pro and GPT-5.6 Luna on standard tests.
The model is reportedly the first openly available model to reach capability tiers previously associated with proprietary frontier models.
The result suggests open-source AI development is narrowing the gap with closed commercial models at similar scale.
