Thinking Machines联合创始人巴雷特·佐夫加入谷歌任研究副总裁

巴雷特·佐夫现已加入谷歌担任研究副总裁，负责强化学习和后训练方面的工作 1。谷歌发言人表示："我们期待巴雷特回归谷歌，为Gemini项目带来他在强化学习和后训练方面的专业知识。" 1

佐夫的职业轨迹最近几个月经历了多次变动。他于2024年10月联合创立了AI初创公司Thinking Machines，与联合创始人Mira Murati一同参与其中 1。在2025年1月，佐夫与Luke Metz从Thinking Machines离职并返回OpenAI 1。在OpenAI仅待5个月后，佐夫于2025年6月离职 1，随后加入谷歌。

Barret Zoph has joined Google as vice president of research, where he will focus on reinforcement learning and post-training work for Gemini 1. This move comes after a tumultuous period in which the AI researcher co-founded and then exited Thinking Machines in rapid succession.

Zoph left OpenAI in October 2024 after two years with the company to co-found Thinking Machines alongside Mira Murati 1. However, the startup's tenure was short-lived; in January 2025, Zoph and Luke Metz departed Thinking Machines, with reports indicating Zoph was dismissed from the role 1. Following this exit, Zoph returned to OpenAI but remained there for only five months before leaving in June 2025 1. A Google spokesperson welcomed his return to the company, stating: "We look forward to Barret returning to Google and bringing his RL and post-training expertise to Gemini" 1.
