    Ben Affleck 讲述他参观 OpenAI 看到 text-to-image 后一度认为电影业已终结,随后发现研究者不熟悉镜头如何拍摄、布光和剪辑,并据此创办 InterPositive。Netflix 于 2026 年 3 月以 5.87 亿美元现金收购该公司;引用内容提到其自建数据集微调开源视频模型,只训练最后一层电影级能力,并用每部新片素材训练私有模型。

    引用Rohan Paul@rohanpaul_ai

    Ben Affleck (Hollywood star & Artists Equity CEO) talks about how he fine-tunes open video models by unfreezing weights and trained only the last cinematic layer so a film crew can hit real production standards. for context, Ben Affleck founded InterPositive in 2022, a 16-person AI shop for film post and Netflix bought it in March 2026 for $587 mn in cash. He needed that model because public video models were trained on his peers' films, and he did not think that was a real business. So InterPositive raised money, shot its own dataset for 8 months on a controlled stage, and used it only as late-stage training. Each new film then trains a private model on its own dailies, so the production keeps the footage and the learning. That is the product Netflix paid $587 million for. ---- From "Bloomberg Live" YouTube channel, (link in comment)

    作者引用 Ben Affleck 在闭门峰会的分享,其创立的 16 人后期 AI 工作室 InterPositive 于 2026 年 3 月被 Netflix 以 5.87 亿美元现金全资收购。做法是解冻开源视频权重、专训最后的电影层,并用在受控舞台实拍 8 个月的私有数据集做后期训练;每部新片在自己的拍摄素材上微调专属私有模型,素材与模型迭代成果留在剧组手里。

    推荐理由:原文梳理了 Ben Affleck 用私有实拍数据微调开源视频模型的思路与产权闭环,读者可以借此对比公共模型与影视级生产的差距。

    Rohan Paul 对比 Ben Affleck 的前后反差:Affleck 在 2026 年 2 月称 AI 只是类似 VFX 的工具、写不出有意义的东西,随后却打造了 VFX 级 AI 工具并以 5.87 亿美元售出。作者引用的上下文称 Affleck 于 2022 年创立电影后期 AI 公司 InterPositive,通过解冻权重微调开源视频模型、仅训练最后一层电影级参数,并用自摄 8 个月数据做后期训练,Netflix 于 2026 年 3 月以 5.87 亿美元现金收购该公司。

    Thomas Wolf 发推调侃 Karpathy 从 X 消失后,Ben Affleck 开始讲微调方法,称要先冻结基座权重、学习率用 2e-4。引用内容介绍 Affleck 通过解冻权重、只训练最后的电影级层来微调开放视频模型,其创办的 InterPositive 自建 8 个月数据集,并被 Netflix 以 5.87 亿美元现金收购。
