Type: AI model
Qwen2.5 is a generation of Alibaba’s open-weight Qwen model family, offered in a wide range of sizes and strong on math, coding, and reasoning relative to its predecessors. It was a widely used baseline before Qwen3. GROUNDING tracks Qwen2.5’s variants, benchmarks, and continued use in open-model work.
