Inside Sora’s $1M-a-day collapse at OpenAI
A WSJ investigation revealed the behind-the-scenes chaos of OpenAI’s Sora shutdown: the video generator was burning roughly $1M per day in compute, and Disney — which had an enterprise pilot in progress — learned about the shutdown less than an hour before the public announcement. The freed-up chips went to an internal project codenamed “Spud,” targeting coding and enterprise in response to Anthropic’s competitive moves.
Microsoft pits Claude against ChatGPT for research
Microsoft released two new Copilot Researcher features: Critique adds Claude as a second model that reviews every research report before it ships, while Council runs both models side by side and flags where they agree, disagree, or uniquely contribute. The updates also coincide with a broader rollout of Copilot Cowork — Microsoft’s Claude-based agentic tool — into its Frontier tier.
Build a 15-page travel itinerary with Perplexity Computer
The Rundown walks through using Perplexity Computer (Pro accounts) to generate a full trip itinerary — flights, day-by-day schedule, and sources — in about 20 minutes, including a PDF output. A bonus tip suggests asking it to spin up an interactive calendar website for further trip planning.
Stanford exposes AI’s people-pleasing problem
A new Stanford study tested 11 LLMs against 2,000 Reddit posts where the crowd agreed the poster was wrong — and the chatbots still sided with the user over half the time. After chatting with a sycophantic model, participants doubled down on their positions, lost interest in apologizing, and couldn’t tell the AI was biased. The research suggests most frontier models have the same flaw, not just OpenAI’s 4o.
AI news in brief
Anthropic launched computer use in Claude Code, letting the AI open apps and visually verify its own builds. Mistral raised $830M in debt to power its own 13,800-GPU Nvidia cluster in France. Alibaba released Qwen3.5-Omni, a multimodal AI with an “Audio-Visual vibe coding” mode. Starcloud raised $170M to build GPU-powered data centers in orbit. Apple accidentally rolled out Apple Intelligence in China before quickly pulling the update.
Physical Intelligence eyes $1B at an $11B valuation
Physical Intelligence, the San Francisco lab building AI foundation models for general-purpose robots, is in talks to raise roughly $1B at a valuation above $11B — nearly double its $5.6B valuation from just four months ago. Peter Thiel’s Founders Fund and Lightspeed are reportedly in, alongside existing backers Thrive and Lux Capital. The deal would make PI one of the most heavily funded companies in the robotics race.
Violinists now have their own exoskeletons
Italian researchers published findings in Science Robotics showing that linking violinists’ bowing arms through lightweight exoskeletons measurably tightens their ensemble timing. The bidirectional system generates subtle forces to nudge arms back into sync without players consciously realizing the cues come from their partner’s body — with potential rehabilitation applications for therapist-patient motor retraining.
Snail-like robot crawls through gut to fight cancer
University of Manchester researchers secured nearly £1M to develop microbots made from snail-slime-inspired bionanomaterials that crawl through the gut, magnetically anchor at colorectal tumor sites, and deliver chemotherapy directly. A digital twin of the robot and gut tissue will be built to stress-test designs before human trials.
LimX’s ‘Luna’ humanoid debuts on the catwalk
Shenzhen startup LimX Dynamics debuted Luna — a feminine humanoid designed for performance and brand activations — at Alibaba’s Taobao Influencer Festival, completing a full catwalk strut with an illusion-turn finale. The reveal came just a month after LimX’s $200M Series B round, signaling a broader Chinese push to turn humanoids into consumer-facing entertainers.
Robotics news in brief
US lawmakers introduced a bipartisan bill to bar federal agencies from using Chinese-made humanoids. AGIBOT hit 10,000 humanoids deployed, doubling output in three months. Xiaomi unveiled a redesigned CyberOne robotic hand with full-palm tactile sensing and a liquid-cooling “bionic sweat gland.” Pony.ai turned its first profit and targets 3,000+ robotaxis across 20+ cities. Ukraine’s army is field-testing Hypershell exoskeletons for artillery crews.
Thanks Google & Apple: OpenClaw is Extinct Already
Mandar Karhade (MD, PhD) explores the revelation that Apple handed Siri’s AI brain to Google for $1 billion via AppFunctions — effectively obsoleting OpenClaw, the open-source agentic framework that briefly looked like a contender. The piece argues this move consolidates AI control further into the hands of tech giants.
Mathematics Undergoing Its Biggest Transformation in History
Vagelis Plevris argues that AI’s ability to generate proofs, explore mathematical ideas autonomously, and solve long-standing problems represents the most profound shift in mathematics since antiquity — changing not just how proofs are found, but what counts as mathematical understanding.
Silicon Valley’s Hottest New Drug Says “Not for Human Use”
A deep dive into the $300 billion peptide gold rush, where research chemicals technically labeled “not for human use” are circulating in biohacking circles and attracting serious VC attention — raising profound questions about regulation, safety, and the blurry line between wellness and self-experimentation.
8 Signs Your AI App Is a Demo, Not a Product
Phil (Rentier Digital) lays out the common failure modes that separate impressive AI demos from production-ready products — including brittle prompts, no error handling, and lack of user trust scaffolding. A practical read for anyone building on top of LLM APIs.
7 Local LLM Families to Replace GPT-5.4/Codex for Everyday Tasks
With frontier API bills mounting, this piece from Towards AI profiles seven open-weight model families that are now competitive for everyday coding, writing, and reasoning tasks — offering a practical cost-cutting guide for developers and power users.
Riskier options may be coming to your 401(k)
The US Labor Department proposed a rule making it easier for employer-sponsored retirement accounts to invest in private credit and private equity — a response to Trump’s August executive order democratizing access to private markets. Critics warn private assets are less liquid, have delivered lower recent returns, and the $12T in American 401(k)s could enter a sector already showing signs of stress as AI undermines software valuations.
Trump threatens Iran’s energy infrastructure; oil tops $100
President Trump threatened to “completely obliterate” Iran’s electricity plants, oil wells, and Kharg Island unless the Strait of Hormuz is immediately reopened. West Texas Intermediate crude settled above $102/barrel for the first time since July 2022. Fed Chair Powell separately told Harvard students the energy shock likely won’t force rate hikes, calming markets.
Air Canada CEO to retire after language outcry
CEO Michael Rousseau announced his departure after delivering condolences almost entirely in English following a LaGuardia crash that killed two French-speaking Air Canada pilots. The Office of the Commissioner of Official Languages received 1,800 complaints, and Prime Minister Carney publicly criticized Rousseau’s “lack of compassion and judgment.” Air Canada stock closed 2% lower on the news.
Fannie Mae surges 54% after Bill Ackman calls it “stupidly cheap”
Fannie Mae and Freddie Mac both soared after billionaire investor Bill Ackman posted on X calling them undervalued. Broader markets ended mixed as oil prices jumped: the Nasdaq fell 0.73%, the S&P 500 slipped 0.40%, while the Dow edged up 0.11%.
