DeepSeek引发资本市场对算力增长展望的担忧 华泰证券分析

fjmyhfvclm2025-01-29  98

华泰证券研报称，DeepSeek发布R1模型及相关应用，以较低的训练成本达到与现有前沿模型相当的效果，引发市场对算力投资的担忧。华泰证券认为：1）DeepSeek主要创新是通过在预训练阶段加入强化学习，DeepSeek V3训练成本相当于Llama3系列的7%，对当前世代AI大模型的降本做出了重要贡献，有望降低现有模型的训练和推理成本；2）目前北美四大AI公司主要通过扩大GPU集群规模的方式探索下一代大模型，DeepSeek的方式是否在下一代模型研发中有效还有待观察。3）DeepSeek这次的成功显示，在Scaling Law放缓的大背景下，中美在大模型技术上的差距有望缩小。
