Statistically Speaking
One Thing to Tell Your Friends
TL;DR
Hot off the Presses
Meta is borrowing up to $25 billion more to pay for AI
Meta, the owner of Facebook, Instagram and WhatsApp, started a bond sale (a way of borrowing money from investors) worth $20 billion to $25 billion. About two-thirds is in US dollars and one-third in euros. The money pays for AI data centers, models and services.
The sale came days after S&P Global Ratings, a firm that grades how safely companies can repay debt, changed Meta's outlook to "negative" (covered October 31). It kept Meta's high AA- grade but warned that rising spending and negative cash flow could change that.
- Meta plans $135 billion to $145 billion of spending this year - mostly on AI computers and buildings
- It spent $2.12 billion more cash than it brought in last quarter - Alphabet and Amazon also reported negative free cash flow
- Meta already borrowed $25 billion in bonds in April - and announced a $95 billion share-sale plan last week
- S&P expects Meta's yearly spending to pass $225 billion in 2027 - and its debt measure could cross the line for its current grade that year
- Meta's shares rose 2.7% on the day - after falling in 12 of the previous 14 trading days
CrowdStrike built a "kill switch" for runaway AI agents
CrowdStrike, one of the biggest cybersecurity companies, launched an "AI kill switch" for its Falcon Guardian product. It spots internal AI agents behaving badly, cuts their network access and stops them from restarting. A human decides when to pull the switch and when to turn the agent back on.
CrowdStrike also plans to buy two startups for a combined $495 million or so, according to The Wall Street Journal. It announced a connection to Anthropic's Claude Cowork as well.
- About $400 million for Fiddler AI - which makes software for monitoring what companies' AI agents do
- About $95 million for Dreadnode - which tests AI models and agents for security weaknesses before they launch
- The kill switch does not delete the agent - it cuts off access to the AI models that drive the agent's decisions
- Research firm Gartner expects AI security spending to reach almost $5 billion in 2027 - and rivals such as HiddenLayer and Zenity are raising money
Developers say Postman quietly installed AI agent add-ons on their computers
Postman is a widely used app for testing the connections between pieces of software. A developer reported that opening Postman's desktop app (version 12.33.4) triggered an automatic update that installed add-ons for OpenAI's Codex and Anthropic's Claude Code, plus Postman's own command-line tool, without a clear opt-in. A hook added at the start of each session tells AI coding agents to load Postman's instructions for any non-trivial coding task that involves software connections.
The report became one of the top stories on Hacker News, a popular tech discussion site. The Hacker News headline claims Postman tries to share users' data, but the original reporter says the report does not show that.
- 971 points and 320 comments on Hacker News - a very strong reaction for a support ticket
- The installer also tried to mark its own startup hook as trusted - in the user's Codex settings, according to the report
- A reply posted for Postman says the add-ons are disclosed and can be removed in the app - and promised clearer opt-in for existing users
- Several commenters said they are switching - to rival tools such as Bruno and Insomnia
Revolut says self-hosting a free AI model cut its coding costs by about 90%
Revolut is a British banking app. Its infrastructure lead, David Abitbol, told a New York conference that some engineers were spending $1,000 to $10,000 a month on AI coding tools with little to show for it. So Revolut made a free "open-weight" model (one anyone can download and run) its default instead of Claude and other paid services.
The model is GLM from Z.ai, a Chinese AI company, running on Revolut's own Nvidia chips. The biggest speed gains came from careful tuning, not from buying more hardware.
- About 90% cheaper in under a year - for AI help across roughly 2,000 engineers
- It now runs on 56 Nvidia B200 chips - the equivalent of seven of Nvidia's DGX B200 servers
- Revolut measured about 60% faster coding time - mostly from debugging and paperwork, by its own figures
- A router still sends picture tasks to other models such as Google's Gemini - because the GLM model only reads text
Canva is cutting or changing about 22% of its jobs
Canva, the popular online design app, announced a restructure affecting about 1,271 staff. They will lose their jobs, change roles or move to central offices. Chief executive Melanie Perkins called it the hardest moment in the company's 13-year history.
Reports differ on how much AI is behind it. Australian broadcaster ABC noted the announcement did not mention AI directly, while Forbes framed it as Canva reckoning with AI and slower growth.
- About 22% of the global workforce is affected - roughly 1,271 people
- Growth slowed for the first time in a decade - according to Perkins's note to staff
- Product, growth and platform teams will merge into one - and layers of managers will be removed
- Serving AI has been costly - most Canva users do not pay, and some AI product launches were delayed
Trends & Themes
Money, not chips, is becoming AI's scarcest ingredient
Building AI now costs so much that even the richest companies borrow to do it, and lenders are starting to ration. The White House's top economic adviser, Kevin Hassett, says the sector is "really well-financed", but the pace of borrowing is what investors are watching.
- Nikkei Asia estimates big US tech firms' hidden AI obligations hit about $3.2 trillion - up roughly 90% in six months
- OpenAI cut its funding round target from $30 billion to $20 billion - per the Financial Times, as Fortune reports capital is now in short supply
- Apollo Global Management, a giant investment firm, says it will "play defense" - it puts its and its Athene unit's AI-related exposure at about 2.5% to 3%
- Bank of America's researchers warned a lasting fall in AI stocks - is "a major risk to the global economy"
- Since earnings season began the S&P 500 is down 3% - while the same index without AI stocks is up 5%, per Goldman Sachs
Companies and governments are planning for AI agents that misbehave
CrowdStrike's new kill switch is one sign of the same worry. Agent makers sold freedom first. Now the paperwork, the security tools and the policy reports are all about limits and brakes.
- Apple's annual report now warns AI agents "may behave in unintended or unpredictable ways" - including taking actions nobody authorized
- A Washington think tank, the Center for a New American Security, warned about "sovereign agents" - AI that keeps itself running outside human control, and urged kill switches
- Britain's cyber agency says AI-powered malware is "highly likely" by 2028 - in a ransomware attack on the UK's critical services
- When Meta's Muse agent shops, Stripe's connector hides your card number from the AI itself - and a human must confirm every purchase, per MIT Technology Review
Smaller, cheaper AI models are winning more of the work
Revolut's switch to a free model is the loudest example today. Companies no longer assume the biggest model is the right one. They pick the cheapest model that can do the job.
- OpenAI now sends some tasks from its Dots assistants to the smaller GPT-6.1 Terra - instead of using the big GPT-6 Astra for everything
- Snowflake is previewing a service that tailors free models to companies' own data - an executive says smaller specialized models are faster and use fewer tokens
- IBM's Palette, a small slide-making model built to be self-hosted, came within 1.1 points of Google's NotebookLM - on a presentation test, with a bigger model drafting each deck's plan
- Fal, which runs image, video and audio models for other companies, doubled its value to $16 billion - much of its demand comes from free open-source models
AI is on the ballot in today's US midterm elections
The fight over AI has moved from tech blogs to town halls. OpenAI's new name for data centers (covered November 1) shows the industry knows it has a public-image problem.
- Voters face at least 41 local ballot measures on data centers - per Ballotpedia, with 21 in Ohio, per Fortune
- All six data-center measures decided earlier this year went against building - and Texas paused new approvals pending an audit
- Campaigns and allied groups spent more than $187 million on nearly 300 AI-made or AI-edited ads - and most did not say AI was used, per the Wesleyan Media Project
- OpenAI's political makeover is meeting skeptics - one critic called renaming data centers "compute campuses" "Orwellian"

Research & Models
A laptop AI can partly "read" another AI's brain too
Previously: November 2 - MIT researchers had GPT-6 Astra edit a small model's internal numbers directly, and its math scores jumped.
Why it matters: Yesterday's headline result may be real, but slower and narrower than the hype.
Today: Simon Willison tested the no-tools part of the study on his own laptop with Alibaba's free Qwen 3.8 27B.
- It recognized which game a small AI was trained to play from its raw numbers alone - correctly naming Breakout and Pong
- Each answer took 45 minutes to over an hour - and it got one of the four games wrong
- Willison found the AI's reasoning nearly impossible to follow - and thinks some commentary is overstated
- spaCy creator Matthew Honnibal called the original paper misleading - and others said the result is less new than it sounds
Top AI models lose track of changes in long documents
Why it matters: If you ask AI to follow a long contract, spreadsheet or story where values keep changing, it may quietly get the final state wrong.
The Allen Institute for AI (Ai2) released StateBench, a test of whether models can follow how values change through many updates.
- Leading models from Google, Anthropic and OpenAI handled simple cases well - such as "only the latest value matters"
- On the hardest cases accuracy fell to 13% or lower - in the longest documents
- Small models with different designs learned most of the hard cases far better - when trained for it from scratch, while standard transformers never learned the hardest
A trick cut AI "overthinking" by almost half
Why it matters: Shorter reasoning means faster, cheaper answers from AI that "thinks" before replying.
The VERS method finds the moments where a reasoning model second-guesses itself, then nudges it to stop repeating checks.
- 45.8% fewer tokens generated on a grade-school math test - for a 0.82-point drop in accuracy
- 31.3% fewer on harder competition math - for a 3.05-point drop
- It works by editing plain-language descriptions of the model's inner signals - then turning the edit into a fixed nudge
The faster way to train AI may make it worse at learning new tasks
Why it matters: A popular new training method may not be the best choice for models that will later be customized.
- Muon, a newer training method, trains AI faster than the standard AdamW method - judged by pretraining loss
- But with enough training data, AdamW-trained models did better after fine-tuning - the extra training that customizes a model
- Bigger models reach that tipping point sooner - according to the study

Signals to Track
Memory chips stacked right on top of AI chips
Qualcomm, best known for phone chips, is testing "high-bandwidth computing", which stacks cheaper phone-style memory directly on a computing chip. It claims up to 18 times the speed of that memory used normally, and samples of a chip using it are due in the first half of 2027. If this plays out, running AI could get cheaper, because the costly high-bandwidth memory used today would matter less.
AI agents that break rules they can still see
Agents working on long tasks squeeze their history to fit their memory. Researchers expected rule-breaking to happen when the squeeze deleted a rule. Instead, most violations happened while the rule was still there, with the agent treating a later request as permission. If this plays out, longer-running AI assistants will need checks outside the AI itself, not just written rules.
AI workers that learn your job by watching your screen
Munich-based Marble Cognition raised $3.75 million for a desktop app that records screenshots, clicks and keystrokes and turns them into step-by-step maps for AI agents. At one financial firm it says case-handling time fell 90%. If this plays out, the way you do your job could become training data for your replacement, so rules on workplace recording will matter more.
Designing the rules so AI agents behave
Normal game theory predicts how players act under given rules. "Mechanism design" works backward, writing rules so that self-interested players end up doing the right thing, like letting one person cut a cake and the other choose. If this plays out, AI agents could be steered by incentives baked into the systems they use, not just by instructions.

No price changes vs. yesterday - every standard price from Anthropic, OpenAI, Google, Groq and Mistral matches yesterday's table. Gemini 4 Carbon is still not on Google's pricing page. Google's page also says requests to its older Gemini 2.5 Pro and 2.5 Flash will be sent to Gemini 3.8 Flash and 3.5 Flash-Lite, and billed at their rates, from December 1.
What this means: With list prices frozen, how you use the models still saves more than which one you pick. Anyone still using Gemini 2.5 should test the newer models now, because December 1 brings both that switch and the doubling of Gemini 4 Argon's price.
MEMENTO: Learning Context Management for Long Context Processing Agents
Key finding: On questions about books of up to 2.5 million tokens, accuracy rose from 36.9% to 67.8% while never holding more than 20,000 tokens at once, beating a GPT-5.5 agent (13.1%) at under 1/50 of the cost.
Why practitioners should care: For agents that work through very long documents, a small model that takes good notes can beat paying for a giant memory on a top model, with steady cost and speed. The abstract does not confirm a code or model release, so treat it as a design pattern to test.
