Key Takeaways
- ByteDance's Seedance 2.5 can generate a person's likeness in professional-looking video from a few reference photos, a first for video models according to @levelsio; a 15-second clip took around 4 minutes and is already in Photo AI. — via 1 2
- AI content authenticity is breaking down: @levelsio argues AI-generated reviews make product judgment impossible, and predicts LLM apps will become free for data while the internet loses real content and training data. — via 1 2 3
- A Shaanxi court acquitted Zhang Heng for fighting back against an illegal demolition and armed intruders, declaring self-defense after nearly three years of detention. — via 1
- Typhoon "Dolphin" prompted a red alert in East China: Ningbo suspended bus and subway, a 9-year-old went missing after waves swept a family in Wenling, and Shanghai's Wukang Road flooded badly. — via 1 2 3 4
- @HiTw93 shared a product-engineering playbook for the AI era: code is only about 30% of the job, decisions on what not to build matter most, and weekly global releases build a long-term brand. — via 1
1. AI and Product Building
- ByteDance's Seedance 2.5 uses a handful of reference images to generate near-professional video of a specific person. @levelsio says it's the first time character similarity in video "reaches the level of image models," with a 15-second clip taking about 4 minutes to generate. The model has been rolled out to Photo AI. — via 1 2
- @levelsio argues AI makes online authenticity unverifiable: website reviews can be AI-generated, and video demos can also be synthetic, so judging a new product from its web presence is impossible without a way to verify realness. He separately predicts LLM apps will move to free-with-data-exchange models, with models actively asking users questions to gather training data; if people stop publishing original content, the internet loses its fresh, authentic material and AI companies must look to chat logs and real-world experience. — via 1 2 3
- Building his game, @tdinh_me found 3D character animation the biggest time sink; Claude was notably weak at it, so a task took 4 hours of combined AI output and manual tuning. The demo is playable and he hopes to finish a first version today — though he says he shouldn't have abandoned the 2D direction. — via 1 2 3
- @HiTw93's product-engineering philosophy: code is only ~30% of a product engineer's job; the real work connects personal pain with user pain, produces an easy-to-use solution, and promotes it. In the AI era, "what not to do" is more important than "what to do," and tokens should be invested in user problems, requirement analysis, data mining, and content friendliness. He recommends weekly releases, no AI-buzzwords, no fake cross-following, and building a long-term brand by writing in English and targeting a global audience; data from sales, traffic, reviews, and issues uncovers the funnel. — via 1
- Subscription growth tactic: @nathanbarry says people subscribe when given an immediate reason; Sam Vander Wielen's pledge to share launch and ad-spend financials dramatically lifted signups, and his book sold out on Amazon. — via 1
2. China: Extreme Weather, Courts, and Public Accountability
- Typhoon "Dolphin" is approaching East China with a red warning; landfall is expected between Sanmen, Zhejiang, and Fuding, Fujian. Ningbo suspended its entire bus and metro network, a family of four in Wenling was knocked over by huge waves and a 9-year-old boy is missing, and Shanghai's Wukang Road was severely flooded. — via 1 2 3 4
- In Xianyang, Shaanxi, the Qindu District Court acquitted Zhang Heng of intentional injury, ruling that he acted in self-defense when multiple people with weapons entered his home during an illegal demolition. Zhang had been held in detention for nearly three years before the decision. — via 1
- Foshan's teacher recruitment is under investigation after the written-exam top 13 all failed the interview while candidates ranked 14-18 all advanced to the physical exam. Because interviews count 60%, and a score below 70 disqualifies the candidate's total grade, the interview effectively has veto power; the education bureau has suspended the recruitment. — via 1
- Economic Observer reporter Li Weiao's article reporting that financial regulator Li Yunze was removed as an NPC deputy was deleted from Weibo. Henan village-bank depositors had used the post's comments to complain about deposits frozen for five years and blocked rights, but Weibo made those comments visible only to the authors and labeled them harmful content. — via 1
