币界网消息，腾讯混元及SSV数字文化实验室联合中科院信工所等机构，正式推出首个覆盖“七体之变”的古文字感知评测基准Chronicles-OCR。该基准包含2800张由专家交叉标注的图像，首次将甲骨文到草书等七种字体的识别难度统一量化。研究团队评测了28个主流多模态大语言模型，结果显示它们在古早字体上几乎全军覆没。在跨时代字符检测任务中，GPT-5和Gemini 2.5 Pro的核心指标接近0，表现最强的模型也仅有16.5。即使直接在图上画框免除定位步骤，最高准确率也只有27.1%，其中Gemini 3.1 Pro在甲骨文上的准确率仅14.0%。这证实了现代模型严重依赖规整的现代版式先验。实验还揭示了一个反直觉的现象：开启思考模式反而会导致古文字识别率下降。
