    Nathan Lambert's Harvard lecture video released: Chinese open-source models lead, US compute advantage about 16x

    The guest lecture video by Nathan Lambert for Harvard CS 2881R "AI Security" has been released. He surveys the state of open-source models and argues that Chinese open-source models lead comprehensively across three dimensions—performance, downloads, and paper citations—while US open-source models lag China by another 3 to 4 months. He judges that distillation is not the key issue, that the total compute of the top five US labs averages 16 times that of the top five Chinese labs, and points out that banning open source is unfeasible in practice and would only suppress economic activity.

    Ethan Mollick said he asked Opus 5.5 to generate an otter video

    Ethan Mollick said he had Opus 5.5 generate a video using the prompt he uses when testing all AI image generation models, "an otter using wifi on a plane." The account appears in his article reviewing the exponential development of AI over the past 30 months. During the same period, on the day his new book Co-Existence was released, Mollick used charts to review the AI progress in the 30 months since the release of his previous book Co-Intelligence, and said the charts in that article were completed by Opus 5.5 in Claude Projects orchestrating multiple agents. Currently there is evidence showing that this video generation action occurred in the above-mentioned review context, with no subsequent developments yet.

    AI mass-generates e-commerce videos: a 5-person team produces over a thousand per day, at under 5 yuan each

    Yunying Research Society analyzes that AIGC is taking over the mass-production stage of e-commerce recommendation videos; a team of about 5 people can generate over a thousand videos in a few minutes, at under 5 yuan each, while manual shooting costs about 100 to 200 yuan per video. The specific approach is to first break out fixed blocks and variable blocks to form a template, then use low-cost models such as Grok Video and the Seedance entry version to test hooks and directions, and after getting data, switch to Veo, Sora, and the Seedance HD version to produce finished products. The article also mentions that Douyin, Xiaohongshu, and Video Accounts all tightened AIGC content review this year, and that Ocean Engine reported at the end of August that it had shut down more than 50,000 violating accounts, and holds that once materials are no longer scarce, judgment and aesthetics become the new threshold.
