前 OpenAI 研究员 Kevin Lu:别折腾 RL 了,互联网才是让大模型进步的关键
Founder Park· 2025-07-11 12:07
「停止研究 RL 吧,研究者更应该将精力投入到产品开发中,真正推动人工智能大规模发展的关键技术是互联网,而不是像 Transformer 这样的模型架 构。」 前 OpenAI 研究员 Kevin Lu 最近更新了一篇博客长文《The Only lmportant Technology ls The Internet》,直指互联网才是推动人工智能进步的核心技术, 是 next-token 预测的完美补充。 Kevin Lu 认为,没有 Transformer 架构,我们可能也会拥有 GPT-4.5 级别的大模型。在 GPT-4 模型以来,基础模型的能力并没有显著的提升,我们可能会 像 2015-2020 年时代的 RL 研究一样,重蹈覆辙,正在进行无关紧要的 RL 研究。 而互联网提供了丰富而海量的数据来源,这些数据具有多样性、能提供自然的学习课程、代表了人们真正关心的能力,并且是一种经济上可行的规模化部 署技术。相比之下,单靠优化模型结构、手工制作数据集或微调算法,都难以带来模型能力质的飞跃。 有趣的是,Kevin Lu 此前在 OpenAI 任职时的主要研究方向之一正是 RL。在推特上,有博主评论道,「当 ...

AI抢人大战:比机器更重要的永远是人
Jing Ji Guan Cha Wang· 2025-07-11 11:11
陈白/文 硅谷如今最抢手的是什么?答案可能超出所有人的想象——不是AI项目,也不是芯片算力,而 是华人软件工程师。 比如就在7月10日,在埃隆·马斯克旗下AI公司Grok 4的发布会上,坐在马斯克身旁的就是两位华人AI技 术负责人。更早一些的7月8日,苹果基础模型团队负责人、著名华人工程师庞若鸣(Ruoming Pang)宣 布离职加入Meta,Meta为他开出了每年数千万美元的薪酬方案。在此之前,扎克伯格还以上亿美元 的"签字费"从OpenAI、苹果等大公司挖走了一批华人学者,他们很多都来自清华大学、北京大学等国 内顶尖高校,且具备OpenAI、Google等科技巨头的核心算法经验。其中有人主导过ChatGPT研发,有人 负责自动驾驶感知系统,堪称AI行业的"梦之队"。 马斯克、扎克伯格们的选择变化有技术积累的原因。从Transformer架构的奠基性论文到ResNet(残差网 络)等影响深远的突破,其中都有华人科学家和工程师的身影。国内顶尖高校对基础学科的严苛训练, 以及其毕业生在OpenAI、Google等机构参与核心算法研发的履历,更是一种权威背书。大模型时代对 复杂数学建模、高效算法设计与海量数据( ...
