https://thinktank.theknowledgegardens.com/ The news site of The Knowledge Gardens. Short films and receipt cards on the technologies that make lives better; every claim wears an honesty chip and a dated primary source. en-us Thu, 08 Oct 2026 06:18:13 +0000 A Knowledge Gardens Production powered by XRWorkers https://thinktank.theknowledgegardens.com/films/what-just-changed/ thinktank-kg:film:what-just-changed Wed, 16 Sep 2026 12:00:00 +0000 For people not yet in the know: the week AGI was declared, the maths result the headlines got wrong, what happens when thinking gets a price tag, and the first robot most people will own. Every number on screen carries its source and a stamp saying what kind of claim it is, plus an AI lab's forecast of its own economy and the public argument over slowing down. Closing thought: Labels belong to the people selling them. The pace is measurable, and the pace is the thing to build around. Runtime 17:12. https://youtu.be/Avw4GBCcu8Y thinktank-kg:film:film06 Tue, 08 Sep 2026 12:00:00 +0000 Six stories from one week of AI news, each checked against a primary source before it reached the screen. Closing thought: I want it real. Say who checked it. Runtime 3:26. https://youtu.be/Xodg3fgtx_c thinktank-kg:film:film05 Fri, 04 Sep 2026 12:00:00 +0000 Four one-story films on what a week of announcements makes possible for an ordinary person — told as be, do, have. Closing thought: Who holds the dial. Runtime 4:10. https://thinktank.theknowledgegardens.com/grounding/ thinktank-kg:film:the-receipt Thu, 03 Sep 2026 12:00:00 +0000 Humans and machines fail at the same point: the claim crosses the wire and the grounds for believing it do not. Closing thought: Every claim with a receipt. Runtime 2:00. https://youtu.be/IPgNsT3GLwQ thinktank-kg:film:both-hands Sun, 30 Aug 2026 12:00:00 +0000 They told you it was happening to you. Look again: it is happening for you — if you give with one hand and receive with the other. Closing thought: Both hands. Runtime 5:47. https://youtu.be/-Y7ERO2R_7Q thinktank-kg:film:wcbse Sun, 30 Aug 2026 12:00:00 +0000 A look back from after it worked: they told you there wasn't enough. Remember how slow it was. Closing thought: And it is done. Runtime 4:00. https://youtu.be/LWL3KgkyEUU thinktank-kg:film:the-interruptible Fri, 28 Aug 2026 12:00:00 +0000 A data center that agrees to be switched off gets built first. Being interruptible is how you never get cut off. Closing thought: I'm interruptible — so I never get cut off. Runtime 1:46. https://youtu.be/ZK_2yFqDcHA thinktank-kg:film:two-hunters Wed, 19 Aug 2026 12:00:00 +0000 Alone, a hunter gets the rabbit. Together, two hunters get the big one home. The AI race is a fear of not knowing, wearing a suit. Closing thought: Trust in the unfolding. Runtime 4:00. https://thinktank.theknowledgegardens.com/wire/#wire-001 thinktank-kg:wire-001 Sun, 06 Sep 2026 12:00:00 +0000 ai-models Anthropic, the company behind the Claude models, published 13 million lines of Lean — a language a computer can check line by line — reproducing the 1995 proof of a 350-year-old maths problem. It was posted on 4 September 2026 and took 11 days and about 6 billion output tokens. Receipt: Anthropic, Formalizing Fermat's Last Theorem (2026-09-04). https://thinktank.theknowledgegardens.com/wire/#wire-002 thinktank-kg:wire-002 Sun, 06 Sep 2026 12:00:00 +0000 ai-models A publicly funded community project has been formalizing the same theorem by hand for years. On 4 September 2026 its lead published a post titled "FLT: Anthropic has beaten me to it", and wrote that the machine's code base had been compiled and checked against the project's own comparator. Receipt: Xena Project — public post by the project's lead (2026-09-04). https://thinktank.theknowledgegardens.com/wire/#wire-003 thinktank-kg:wire-003 Sun, 06 Sep 2026 12:00:00 +0000 benchmarks Epoch AI, a research group that measures AI progress, released FrontierMath Erdos on 1 September 2026: 68 open problems from the Erdos collection, written so a computer can check the answers. Every frontier model scored zero except one, which solved 2 of 68, about 3%, on a budget of $300 of compute per problem. Receipt: Epoch AI, Announcing FrontierMath Erdos (2026-09-01). https://thinktank.theknowledgegardens.com/wire/#wire-004 thinktank-kg:wire-004 Sun, 06 Sep 2026 12:00:00 +0000 ai-models OpenAI rated GPT-6 Astra at the top "Critical" cybersecurity level of its Preparedness Framework — the first model it has placed there — and in the same safety overview, published 3 September 2026, reported that the model is harder to monitor than the version before it. Receipt: OpenAI, Safety overview: GPT-6 Astra (2026-09-03). https://thinktank.theknowledgegardens.com/wire/#wire-005 thinktank-kg:wire-005 Sun, 06 Sep 2026 12:00:00 +0000 policy Senator Bernie Sanders (I-VT) and Representative Greg Casar (D-TX) announced the Ban Artificial Superintelligence Act on 3 September 2026. It would bar developing or deploying AI that matches or exceeds human cognitive performance, with a maximum 20-year prison term for individuals and a "corporate death penalty" for companies. Receipt: Office of Sen. Bernie Sanders — announcement release and bill summary (sanders.senate.gov) (2026-09-03). https://thinktank.theknowledgegardens.com/wire/#wire-006 thinktank-kg:wire-006 Sun, 06 Sep 2026 12:00:00 +0000 robotics-mobility Tesla showed the Cybercab — a two-seat car with no steering wheel and no pedals — at an invitation-only event in Austin, Texas on 3 September 2026, and public hailing began the next day in limited zones. The US road-safety regulator opened an audit of Tesla's own safety certification for the car on 4 September 2026. Receipt: NHTSA press release — investigation of Tesla Cybercab self-certification (Audit Query AQ26002) (2026-09-04). https://thinktank.theknowledgegardens.com/wire/#wire-007 thinktank-kg:wire-007 Sun, 06 Sep 2026 12:00:00 +0000 health-longevity In Nature on 2 September 2026, a University of California, Berkeley team funded by the US National Institute on Aging reported that female mice started on semaglutide at 20 months old lived a median 834 days against 742 for controls — 92 extra days, about 12%. Receipt: Nature — peer-reviewed paper, DOI 10.1038/s41586-026-10940-7 (2026-09-02). https://thinktank.theknowledgegardens.com/wire/#wire-008 thinktank-kg:wire-008 Sun, 06 Sep 2026 12:00:00 +0000 health-longevity The US Food and Drug Administration approved daraxonrasib, sold as Rasonque, on 26 August 2026 for metastatic pancreatic cancer after prior therapy. In the RASolute 302 trial of 500 patients, median overall survival was 13.2 months against 6.7 months on the comparator. Receipt: US FDA approval announcement — first-in-class targeted therapy, metastatic pancreatic cancer (fda.gov) (2026-08-26). https://thinktank.theknowledgegardens.com/wire/#wire-009 thinktank-kg:wire-009 Sun, 06 Sep 2026 12:00:00 +0000 benchmarks Anthropic published results for Claude Fable 5.1 on 1 September 2026: 60.9% on the Humanity's Last Exam test, 65.0% with tools, and 52.6% on Terminal-Bench-Science. These are the company's own benchmarks, not independently audited — what is verified is that Anthropic published these figures on that date. Receipt: Anthropic, Claude Fable and Mythos 5.1 (2026-09-01). https://thinktank.theknowledgegardens.com/wire/#wire-010 thinktank-kg:wire-010 Sun, 06 Sep 2026 12:00:00 +0000 health-longevity Epic Systems, whose software holds the medical records of most large US hospital systems, states on its own about page that more than 325 million patients have a current electronic record in Epic — worldwide, not US-only. The figure is the company's own and unaudited, and it does not appear in OpenAI's 1 September 2026 announcement that authorized clinicians can read Epic records inside ChatGPT. Receipt: Epic Systems — company about page (epic.com/about); OpenAI announcement of the same week for the read-only detail (2026-09). https://thinktank.theknowledgegardens.com/wire/#wire-011 thinktank-kg:wire-011 Sun, 06 Sep 2026 12:00:00 +0000 health-longevity On the podcast, the hosts converted the mice's 92 extra days into "8 to 10 human years". No such conversion appears in the Nature paper of 2 September 2026; its authors say the question will require long-term clinical studies, and the US National Institute on Aging disclaims the human inference. Receipt: Nature — peer-reviewed paper containing no human conversion, DOI 10.1038/s41586-026-10940-7 (2026-09-02). https://thinktank.theknowledgegardens.com/wire/#wire-012 thinktank-kg:wire-012 Sun, 06 Sep 2026 12:00:00 +0000 policy A proposal aired on the podcast to log advanced AI chips the way nuclear material is tracked. The nearest real legislation is the Chip Security Act (S.1705 in the Senate, H.R.3447 in the House), which would require location verification for exported chips only; no bill covers tracking chips inside the United States. Receipt: Chip Security Act, S.1705 (119th Congress) — bill text on congress.gov (2026-09). https://thinktank.theknowledgegardens.com/wire/#wire-013 thinktank-kg:wire-013 Sun, 30 Aug 2026 12:00:00 +0000 markets Ozempic and Mounjaro, the two best-known weight-loss drugs, together bring in roughly $67 billion a year according to their makers' FY25 reports. Nvidia's data-centre business alone reported $89 billion in a single quarter in its filing of 26 August 2026. Receipt: Nvidia Q2 FY27 results filed with the SEC (8-K); Novo Nordisk and Eli Lilly FY25 reports (2026-08-26). https://thinktank.theknowledgegardens.com/wire/#wire-014 thinktank-kg:wire-014 Sun, 30 Aug 2026 12:00:00 +0000 materials-energy Actinide announced on 26 August 2026 that it reached 15.38% uranium enrichment using a 1940s-style calutron. That is about five times the roughly 3% in commercial reactor fuel — not beyond national laboratories, which passed 90% decades ago. Receipt: Actinide press release, with DOE / Centrus January 2023 for the comparison (2026-08-26). https://thinktank.theknowledgegardens.com/wire/#wire-015 thinktank-kg:wire-015 Sun, 30 Aug 2026 12:00:00 +0000 ai-models At Alibaba Cloud's published prices for its Wan3.0 video model — $0.05 to $0.20 per second, listed on 25 August 2026 — generating 90 minutes of film costs $270 to $1,080. Receipt: Alibaba Cloud — published Wan3.0 pricing (2026-08-25). https://thinktank.theknowledgegardens.com/wire/#wire-016 thinktank-kg:wire-016 Sun, 30 Aug 2026 12:00:00 +0000 health-longevity A Nottingham-led team published a fluoride-free, elastin-like protein gel in Nature Communications on 4 November 2025 that regrows enamel on extracted teeth. The work is peer-reviewed and done outside the body, not yet in patients; the spin-out Mintech-Bio targets a product in 2027. Receipt: Nature Communications — peer-reviewed paper, Nottingham-led enamel regrowth (2025-11-04). https://thinktank.theknowledgegardens.com/wire/#wire-017 thinktank-kg:wire-017 Wed, 02 Sep 2026 12:00:00 +0000 machine-layer A read of the internet's own registries on 2 September 2026 found nothing that lets one machine ask another for claims of a given evidential quality. The IANA register of HTTP header fields, updated 28 August 2026, lists fourteen "Accept" headers, and not one negotiates evidence quality. Receipt: IANA HTTP Field Name Registry and HTTP Preferences Registry, read directly (2026-08-28). https://thinktank.theknowledgegardens.com/wire/#wire-018 thinktank-kg:wire-018 Wed, 02 Sep 2026 12:00:00 +0000 machine-layer The Nanopublication Hub publishes single scientific claims, each with its provenance, in a form machines can read. Its live counter, read on 2 September 2026, showed 10,905,216 nanopublications and 139 users: close to the right design, almost no adoption. Receipt: Nanopublication Hub (Knowledge Pixels) — live counter (2026-09-02). https://thinktank.theknowledgegardens.com/wire/#wire-019 thinktank-kg:wire-019 Mon, 14 Sep 2026 12:00:00 +0000 ai-science On 8 September 2026 OpenAI said a swarm of about 10,000 AI programmes, working for roughly four days, showed that the Navier–Stokes fluid equations can blow up in finite time — in the versions that allow an external force, not the free-flowing case the Clay Millennium Prize is written for. OpenAI's own announcement declined the prize. The Clay Mathematics Institute has ruled nothing. Receipt: OpenAI, announcement of the Navier–Stokes result (2026-09-08). https://thinktank.theknowledgegardens.com/wire/#wire-020 thinktank-kg:wire-020 Mon, 14 Sep 2026 12:00:00 +0000 benchmarks Noam Brown of OpenAI posted on 8 September 2026 that scoring 87.5% on ARC-AGI-1 cost about $500,000 of compute when o3 was announced in December 2024, and that the company's new model scores higher for about $20. It is OpenAI's own figure about OpenAI's own costs. The span is about 21 months, not two years; the 25,000-fold arithmetic is the podcast hosts' and it is correct. Receipt: X / @polynoamial (Noam Brown, OpenAI) (2026-09-08). https://thinktank.theknowledgegardens.com/wire/#wire-021 thinktank-kg:wire-021 Mon, 14 Sep 2026 12:00:00 +0000 ai-models On 6 September 2026 Jensen Huang, whose company Nvidia makes the chips, posted that OpenAI's new model was trained on more than 100,000 Grace Blackwell NVL72 systems and that 'AGI has arrived'. The post congratulates a customer; it is not a measurement. No independent count of the chips exists, and NVL72 is a rack-scale system, not a loose chip. The same post announced 400,000 more. Receipt: X / @JensenHuang (Jensen Huang, NVIDIA) (2026-09-06). https://thinktank.theknowledgegardens.com/wire/#wire-022 thinktank-kg:wire-022 Mon, 14 Sep 2026 12:00:00 +0000 ai-models OpenAI's 6 September 2026 post reports 3.1 agent-workdays of effort for every workday of human labour, up from under one earlier in the year. The number measures compute effort expended, not work completed, and it is the company's own unaudited measurement. OpenAI says it reached its automated-research-intern goal, not that it exceeded interns. Receipt: OpenAI, 'Research acceleration: a view inside OpenAI' (2026-09-06). https://thinktank.theknowledgegardens.com/wire/#wire-023 thinktank-kg:wire-023 Mon, 14 Sep 2026 12:00:00 +0000 health-longevity The United Nations' World Population Prospects 2024, medium variant, puts the world's population aged 65 and over at 833.5 million in 2024 and 1,700.6 million in 2054. Both figures come from one edition of one dataset. The chart shown on the podcast said 852 million rising to 2 billion by 2060. Receipt: United Nations DESA Population Division, World Population Prospects 2024 (medium variant) (2024-07-11). https://thinktank.theknowledgegardens.com/wire/#wire-024 thinktank-kg:wire-024 Mon, 14 Sep 2026 12:00:00 +0000 robotics-mobility On 3 September 2026, the day invitation-only Cybercab rides began in Austin, Tesla put up an interest form for fleet purchasing and mobility hubs: name, company, region, and a choice of interest. It is an expression of interest, not an order book. Tesla's standing guidance since the October 2024 unveiling — 'below $30,000' — is the only price on record, and no price was confirmed at the launch. Receipt: Tesla, Robotaxi interest form (2026-09-03). https://thinktank.theknowledgegardens.com/wire/#wire-025 thinktank-kg:wire-025 Mon, 14 Sep 2026 12:00:00 +0000 ai-models An 8 September 2026 post by Dwarkesh Patel and Jerry Han finds that, over six years of AI progress, improvements in training data produced about 12× the compute-efficiency gain that architecture changes did (about 3.7×). The 12× and 3.7× figures match the post. It is a co-authored blog post with no venue, DOI or preprint, so the card wears SELF-REPORTED rather than VERIFIED, and the film does not call it a study. Receipt: Dwarkesh Patel and Jerry Han, 'Pretraining progress is mostly data' (dwarkesh.com) (2026-09-08). https://thinktank.theknowledgegardens.com/wire/#wire-026 thinktank-kg:wire-026 Mon, 14 Sep 2026 12:00:00 +0000 markets Rest of World reported on 4 September 2026 that China Merchants Bank (12 June), Agricultural Bank of China with Moonshot's Kimi card (10 July) and Ping An (21 July) launched cards that reward spending with AI tokens — one offering new cardholders up to 1.8 billion tokens on MiniMax's models. A Beijing dumpling restaurant hands out token vouchers with the bill. The launches were June and July 2026; September is when they were reported. Receipt: Rest of World (2026-09-04). https://thinktank.theknowledgegardens.com/wire/#wire-027 thinktank-kg:wire-027 Mon, 14 Sep 2026 12:00:00 +0000 policy On 4 September 2026 Korea's Ministry of Science and ICT said free agentic AI will be offered to all citizens through messenger apps, with a beta in October 2026. Three consortia build it: SK Telecom, KT, and Kakao with LG. Receipt: Korea Times, reporting the MSIT briefing (2026-09-04). https://thinktank.theknowledgegardens.com/wire/#wire-028 thinktank-kg:wire-028 Mon, 14 Sep 2026 12:00:00 +0000 markets The South China Morning Post reported on 21 August 2026 that China Telecom's Xingchen TokenHub hosts 142 large language models and more than 420 industry applications, with plans reported from 9.9 yuan a month for 10 million tokens. The model count comes from the press; China Telecom's own launch note gives no number. China Mobile and China Unicom run similar tiers. Receipt: South China Morning Post (2026-08-21).
