Qwen2.5 72B

Model Overview

Qwen2.5 72B is Alibaba’s flagship open-weights model, released on September 19, 2024 as part of the Qwen2.5 series. The model delivers leading Chinese-language understanding, strong multilingual coverage across 29+ languages, and a 131K context window. On academic benchmarks, Qwen2.5 72B matches or exceeds Llama 3.1 70B on MMLU (86.1) and significantly outperforms it on math (83.1 vs 71.8) and coding (86.6 HumanEval pass@1). Released under the Qwen License — which permits commercial use with minimal restrictions — Qwen2.5 72B has become a top choice for Chinese-market deployments, bilingual RAG systems, and code-generation pipelines where Chinese context matters. The model ships with native support for structured output, tool calling, and long-document summarization.
