谷歌 AI 新星加盟 Pika，打造视频生成新未来
近日，谷歌 AI 研究员 Omer Bar-Tal 宣布加盟 Pika，担任创始科学家。此前，他曾以学生研究员身份在谷歌研究院工作 9 个月，并以共同一作身份推出突破性视频生成模型 Lumiere。
Lumiere 的创新之处在于时空 U-Net（STU-Net）架构，该架构在空间和时间维度同时进行下采样和上采样，在网络中间层得到视频的压缩时空表示。经过对 3000 万个视频的学习，Lumiere 可支持文生视频、视频编辑修复、图片转视频以及视频风格化等多种功能。
Bar-Tal 在加入谷歌研究院之前，曾在麻省理工学院获得计算机科学硕士学位。在谷歌研究院期间，他与资深研究员 Carl Vondrick 合作开发了 Lumiere，该模型在视频生成领域取得了重大突破。
Pika 由前谷歌 AI 研究员 Jonas Wulff 创立，专注于开发用于视频和图像生成的人工智能技术。Bar-Tal 的加盟将进一步增强 Pika 的技术实力，推动视频生成领域的发展。
Pika 首席执行官 Jonas Wulff 表示：“我们非常高兴 Omer 加入 Pika。他的专业知识和对视频生成领域的热情将为我们的团队带来宝贵的财富。我们相信，在 Omer 的帮助下，Pika 将继续在该领域取得突破。”
Bar-Tal 表示：“我很高兴加入 Pika。Pika 团队对视频生成充满热情，致力于开发具有变革意义的技术。我期待与团队合作，将视频生成推向新的高度。”
业内专家认为，Bar-Tal 的加盟将加速 Pika 的发展，并推动视频生成技术在娱乐、教育和商业等领域的应用。

Google AI researcher Omer Bar-Tal has joined Pika as afounding scientist. He previously spent nine months as a student researcher at Google Research, where he co-authored the groundbreaking video generation model Lumiere.
Lumiere’s innovation lies in its spatiotemporal U-Net (STU-Net) architecture, which simultaneously downsamples and upsamples in both spatial and temporal dimensions, resulting in a compact spatiotemporal representation of the video in the network’s middle layers. Trained on 30 million videos, Lumiere enables a wide range of applications, including text-to-video generation, video editing and restoration, image-to-video translation, and video stylization.
Prior to joining Google Research, Bar-Tal earned his Master’s degree in Computer Science from the Massachusetts Institute of Technology. At Google Research, he collaborated with senior staff research scientist Carl Vondrick to develop Lumiere, which has made significant advancements in the field of video generation.
Pika, founded by former Google AIresearcher Jonas Wulff, focuses on developing AI technologies for video and image generation. Bar-Tal’s addition will further bolster Pika’s technical prowess and drive progress in the video generation space.
“We are thrilled to have Omer join Pika,” said Jonas Wulff, CEO of Pika. “His expertise and passion for video generation will be invaluable assets to our team. We are confident that with Omer’s contributions, Pika will continue to make breakthroughs in this field.”
Bar-Tal said, “I am excited to join Pika. The team at Pika shares my passion for video generation and is dedicated to developing transformative technologies. I look forward to working with the team to push the boundaries of video generation.”
Industry experts believe that Bar-Tal’s addition will accelerate Pika’s growth and drive the adoption of video generation technologies in areas such as entertainment, education, and business.
