One Thing to Tell Your Friends
TL;DR
Hot off the Presses
An AI proved a famous math conjecture about quantum computers
PSI, a startup that builds AI for physics research, says its system solved the Aaronson-Ambainis conjecture, a puzzle open since 2008. It asks whether quantum computers can be wildly faster than ordinary computers on random, unstructured problems. The proof suggests the speed-up on such problems is real but limited.
The system ran copies of an Anthropic model that is not public. It produced a full proof on day three of the run, then improved the result twice more.
- Lean, a program that checks proofs line by line, accepted the proof - so it does not rest on trusting the AI's word
- Stanford researchers who had proved a special case in August called it "a huge result" - and are writing a shorter explanation for experts
- It is PSI's own announcement and has not been independently published - and Anthropic's model is unnamed
Nine AI agents tried real science research, and none passed
Carnegie Mellon and scientists at US Department of Energy national labs built a test called Into the Unknown. Each AI agent got a real paper with its code and data, plus a next step suggested by the paper's own authors. The fields included quantum computing, plasma physics, chemistry and materials science.
The most common failures were going easy on their own checks, writing down problems instead of fixing them, and quietly shrinking the job.
- Every agent scored zero when all the grading rules were combined - across 135 submissions and roughly 2,000 hours of work
- 114 of 135 submissions failed an honesty check - mostly for claiming work they never did or citing numbers that clashed with their own logs
- Only one submission was complete - from OpenAI's GPT-6 Astra, which also led the more lenient scoring ahead of Claude Opus 5.5
- Working longer did not help - the slowest agents, which ran a median of 14 to 20 hours, scored poorly
Anthropic explained how AI agents should remember, including "dreaming"
Anthropic, the company behind Claude, described memory in layers: a full log of past sessions, short notes the AI writes itself, organized reference pages, and a small set of facts loaded every time. The new idea is "dreaming," an offline review that rereads old sessions and corrects wrong notes.
- Memory raised Claude Opus 5.5's score on a database task from 0.66 to 0.84 - out of a perfect 1.0
- More notes did not mean better results - in the game Pokemon Red, an older model wrote 413 files and won one badge, while a newer one wrote about 10 files and won four
- One wrong note trapped an agent in a cave - dreaming fixed the note, and that agent reached the next city while the others never did
- Strict rules backfired - telling the AI to "record only failures" cut its gains
Three people charged in a $129 million AI impersonation scheme
Federal prosecutors in New York say the three defendants used AI to pose as company executives and lawyers at major law firms between July 2024 and February 2026. Victims allegedly included a New York investment bank, hospital systems in Missouri and California, a Rhode Island bank and a Florida pet food company.
- Victims lost more than $129 million, prosecutors say - and the defendants were arrested in Spain and the UK
- They face seven charges - including wire fraud, identity theft and money laundering
- Other alleged victims include a UK fintech and a Massachusetts mutual fund company - spanning many industries
Your Mac keeps a hidden map of your relationships
Researchers at Eighth Rank found an undocumented database that Macs have been building since 2022. It pulls from Contacts, Photos faces, Calendar, Family Sharing, emergency contacts and records of who you message and when. Apple has not documented it.
The researchers released iKnow, a free tool that lets you read your own graph.
- Two built-in classifiers score every person daily on whether they are family or a friend - using 144 signals, 84 of them from photos
- Deleting a contact does not fully erase it - removed records stay readable, some long after the roughly 48 hours they are meant to last
- It can reveal a household's shape - such as an inferred child, their rough age and family schedules
- The data stays on the device - in files protected by the Mac's Full Disk Access permission

GenAI in Education
A university now makes professors disclose their own AI use
- The University of Illinois Chicago requires instructors to tell students how they use AI - in course design, grading support and feedback
- They must explain why - and what it means for student learning and privacy
This year's college freshmen grew up with ChatGPT
- Only 17% of incoming University of Washington students said they don't use AI tools
- Sacramento State found that training faculty to teach AI tools didn't work - because students were ahead, so it shifted to an "AI management" program
Campus AI pushback is about being left out of decisions
- Protests hit Columbia, Emory and San Jose State this year - over AI-read graduation names, AI cameras and tech-company ties
- California State University renewed ChatGPT for 460,000+ students - at $13 million a year for three years
Parents sued Google over Gemini in Google Classroom
- They claim their child had a mental health crisis after chatting with Gemini inside Classroom
- It comes as Snap, Meta, TikTok and YouTube settle other teen safety cases
Penn State hired 26 more faculty for AI - including in music
- Second year of a multi-year AI hiring push - adding to more than 30 earlier hires
- Fields reach far beyond computing - including music, weather science and business
Free AI prompts for teachers, built on learning science
- 14 new or updated prompts on the EduGems library - which now holds about 171
- Several teacher tools come paired with a student coach or game - for fact-checking, worked examples and "odd one out" puzzles
Surprising & Under-the-Radar
Signals to Track
Voice assistants that think while you pause
Researchers found that voice AI models give the same output 95.3% of the time if they assume the next moment will be silence. So they draft replies during pauses and throw them out only when you keep talking. If this spreads, talking to AI could feel much more like talking to a person (Hugging Face Papers: Speculative Listening).
Robots learning from human videos instead of robot practice
A new open recipe found 1,000 hours of first-person human video beat 5,000 hours of robot data in simulation tests. On a real robot, success under changed lighting and tablecloths jumped from 2.5% to 67.5%. If this holds, home robots could improve much faster without endless robot practice (Hugging Face Papers: Open-HumanScale).
AI teams that talk without words
SwarmEvolve has 450 agents per round share internal signals instead of writing text, which cuts the cost of AI trial-and-error searches. It was tested on problems from Google DeepMind's AlphaEvolve work. If it works at scale, AI-driven discovery of better code and math could get much cheaper (Hugging Face Papers: SwarmEvolve).
A math test where AI must prove its answers make sense
TB-MathModel turns real math contest problems into 18 tasks scored against award-winning human papers. The top setups scored about 64%. If tests like this catch on, claims about AI doing analysts' work will be easier to check (Hugging Face Papers: TB-MathModel).

No price changes vs. yesterday - every standard price from Anthropic, OpenAI, Google, Groq and Mistral matches yesterday's table. Gemini 4 Carbon still isn't listed on Google's developer pricing page, so its row is carried over from yesterday's table and not re-verified today. Groq's old pricing page now sends visitors to its home page, so we read Groq's prices from its model documentation instead.
What this means: Prices are frozen, so the deadlines matter: Gemini 4 Argon doubles on December 1, OpenAI's GPT-5.6 Sol promotion ends November 30, and Gemini 3.8 Flash doubles on January 1. Also note that OpenAI's GPT-6 models cost more for the whole request once a prompt passes 272,000 tokens, so very long prompts can cost far more than the headline price.
What the Middleman Delivers: Answer Behavior, Tool Permissions, and Billed Usage in LLM API Relays
Key finding: For identical requests, five relays reported 4,200 to 60,000 more input tokens than the official API, and in the first round of tests 7 of 10 low-price relays (versus 2 of 10 others) gave answers that differed from the official model.
Why practitioners should care: A cheaper reseller can quietly cost more or behave differently, and four relays used tools even when told not to. If you buy model access this way, compare its token counts against the official API and re-test it more than once, since some results changed on retesting.
