待验证模型性能的瓶颈不仅在于参数量，更在于表示的质量，嵌入空间坍缩的模型即使参数再多也无法充分发挥潜力71% 相似待验证Performance improvements in large language models have hit a bottleneck, with benchmark score improvements becoming marginal and some metrics falling short of previous versions.70% 相似待验证当前大模型能力的瓶颈已从模型不够聪明转移到系统不够完善，模型能力的边际提升越来越小而系统工程层面的优化空间巨大70% 相似待验证小模型比大模型更易发生嵌入坍缩，原因包括参数容量有限、优化捷径倾向和各向异性问题被放大69% 相似
