1月20日,发布DeepSeek-R1大模型,在后训练阶段大规模使用了强化学习技术,在仅有极少标注数据的情况下,极大提升了模型推理能力。在数学、代码、自然语言推理等任务上,性能比肩OpenAIo1正式版,API服务定价为每百万输入tokens1元(缓存命中)/4元(缓存未命中),每百万输出tokens16元,均大幅低于同性能下海外主流模型价格。DeepSeek-R1模型上线后引发用户广泛关注,1月27日以来,DeepSeekAPP已经连续多日位居中国、美国等IOS免费榜榜首。
海通证券认为近年来国内模型进步显著,2024年Kimi、豆包等模型逐步出圈,并带来用户使用习惯的养成。本次DeepSeek-R1的发布,在性能对齐OpenAI-o1正式版、但成本更低,有望带来下游更为广泛的应用落地和商业化机会,持续看好AI应用的投资机会。
