GLM-5.2 长上下文学习能力显著提升，GPT-5 需 300 天

This is a remarkable graph that reinforces the same point as autoresearch results, WeirdML, "takeout delivery bench", and all other long multi-turn scenarios. Notice: *GLM-5.2 isn't any better than 5-5.1 for the first ≈150 days*. But it learns in-context. GPT-5 takes 300 days.
