Open-Source Models Close the Gap: GLM-5.2 and Qwen 3.7 Challenge Frontier Systems

Two open-source models are drawing attention for benchmark performances that narrow the gap with proprietary frontier systems. GLM-5.2, from Zhipu AI, is topping open-source leaderboards with a one-million-token context window and strong coding performance, according to @marcopapa99.
