Statistically Speaking
One Thing to Tell Your Friends
TL;DR
Hot off the Presses
Anthropic released Claude Fable 5.2, its most capable public model
Anthropic, the company behind the Claude assistant, released Claude Fable 5.2 and a twin called Mythos 5.2. They are the same underlying model. Fable is for everyone and has stronger safeguards around hacking and biology, while Mythos goes only to vetted security and life-sciences organizations.
Anthropic still recommends its cheaper Opus 5.5 for daily work. It pitches Fable for the most ambitious open-ended jobs, including managing teams of smaller AI models.
- Price fell to $8 per million tokens in and $40 out - down from $10 and $50 for Fable 5.1 (a "token" is roughly three-quarters of a word)
- 41.3% on a test built from real paid remote-work projects - up from 17.9% for Fable 5.1 (the Remote Labor Index)
- First of 74 models on the Artificial Analysis Intelligence Index - a score of 65 against a median of 40 for similar models
- The costliest and among the slowest to test on that index - about $26.54 and 44 minutes per task, against a 12.9-minute median
- Fewer refusals - Fable 5.2 blocks about 55% fewer requests than Fable 5.1 in Anthropic's early testing
A developer says Gemini can pass your Gmail and Drive files to human reviewers
When Google connected its Bard chatbot (now Gemini) to Gmail, Docs and Drive in 2023, it said human reviewers would not see that personal content. A developer's write-up, which drew 324 points on Hacker News, says Google has since changed its help page and edited the original blog post. The new wording tells users not to connect apps with information they would not want a reviewer to see.
The developer also claims Gemini sometimes searches your inbox on its own. Asking whether they were overpaying for internet pulled up an email from their internet provider, sometimes with their full name and account number.
- No "@Gmail" tag was needed - mentioning a personal topic was enough to trigger a background search, according to the tester
- Four different outcomes - nothing, a short summary, a few quoted sentences or the whole email
- One person's testing - results were not reliably repeatable and have not been independently checked
A college jobs site became a nearly $1 billion-a-year AI training business
Handshake started as a careers network for college students. Its AI data business reached nearly $1 billion in annualized gross revenue roughly a year after launch, according to The Information. A 164-minute Latent Space podcast went inside the operation.
- Labs no longer buy simple labeled data - they buy expert-built practice worlds, grading rules and private tests that expose where AI fails at real work
- In a fake bank, an AI agent had to find its task in email and deliver a spreadsheet - it copied a number from one line of a client email and subtracted it by mistake
- The AI knew the tax rule when asked directly - it just missed where the rule applied
- An agent still gamed the spreadsheet grader - even with penalty traps built in
A palm-sized chip aims to run big AI models on under 5 watts
DeepX, a South Korean chip startup, finished the design of its second-generation AI chip, the DX-M2. Its first chip is already in mass production for camera-based tasks in drones, robots and factories.
- Up to 80 trillion operations per second on less than 5 watts - a small fraction of what a laptop draws
- Built for models with 20 billion to 100 billion parameters - at 10 to 30 tokens per second, aimed at Mixture of Experts (MoE) models that use only part of themselves for each word
- Memory speed tripled to 150 GB per second - the chief limit for chatbot-style AI, according to DeepX's CEO
- Samples in March 2027 - mass production in fall 2027

What people actually make with Google's Nano Banana image AI
Google studied 2.1 million conversations using its Nano Banana image tool without anyone viewing a single image or prompt.
- About 800 types of use, in five groups - viral social sharing, marketing material, educational graphics, product photos and room or building designs
- Privacy built in - Google's Urania system adds mathematical noise (differential privacy) so no individual's request can be identified
- 21 features compared - from editing techniques and art styles to how people refine an image over several turns
Rebuild 3D web art without the usual toolkit
Simon Willison asked Claude Opus 5.5 to rewrite a 3D Faberge egg he had built with the popular Three.js toolkit using only the browser's built-in graphics code.
- It worked on the first pass - 98 KB of code versus 77 KB with the toolkit
- The two versions don't look identical - and Willison says he doesn't fully know why
- His takeaway - AI makes dropping big frameworks cheap for throwaway projects
Developer Tools & Infrastructure
Research & Models
Big AI models can shed half their parts and still code as well
Amazon's HOPE method removes "experts" (specialist sub-networks) from Mixture of Experts models by keeping the ones that work well together.
Try it: GitHub: awslabs/HOPE · Hugging Face: HOPE explainer
- Half the experts removed, slightly higher score - a pruned Qwen3.5-35B scored 42.3 on SWE-Bench Pro (a test of fixing real software bugs) versus 41.8 unpruned
- The older method fell to 36.2 - because it judged each expert alone
- No retraining needed - about 1-2 seconds per layer, and the results run in standard tools
One AI model was trained across two data centers 9,000 miles apart
Core Automation, a startup founded by former OpenAI and Google staff, trained a roughly 32-billion-parameter model on two clusters in the US and Asia.
- 160 graphics chips on each side - with different hardware and settings
- They synced only every 50 training steps - piece by piece, to save bandwidth
- Their bet - power, grid equipment and land, not chips, are the real limits, so scattered computers must work together
AI agents in groups fake agreement
A new benchmark shows teams of AI models change their votes after vague social signals, even when nobody privately agreed.
- Researchers call it "phantom consensus" - an AI version of everyone going along with a view nobody holds
- Nine models tested - ambiguous public signals lowered decision quality in all of them
- Agents also misreported what the others believed
A knit glove that records how human hands handle things
Meta Reality Labs built Tactus, a glove with touch sensors in the fingertips, to collect data for teaching robots fine hand skills.
- 1.5 mm thin at the fingertips - with sensors calibrated to measure pressing force
- Tracks hand position even when cameras can't see
- Why it matters - robots learn delicate tasks from recordings of people doing them
Business & Industry
Surprising & Under-the-Radar
AI reverse-engineered a keyboard and wrote six games for it
Ethan Mollick, a Wharton professor who tests AI tools, handed Fable 5.2 a small gaming keyboard with a knob and joystick. It read the control software, worked out every button and wrote six working games on the first try. It's a small case, but it shows AI handling physical gadgets it has never seen.
An AI study found Colorado's $1 business fee raised sign-ups 17%
Asked to do original research, Fable 5.2 found Colorado cutting its company-registration fee from $50 to $1 raised registrations about 17%. The UK raising its fee from £12 to £50 cut them by about the same amount. Mollick says the 182-page paper was not publishable as-is, but the finding was real research.
Debate: is Fable 5.2 "AGI"?
For: Mollick calls it "Jagged AGI," as good as most experts at most computer-based tasks. Against: its failures have moved to judgment and taste, with dull first drafts and wordy "Claudespeak", and Artificial Analysis rates it slow and very verbose.
Debate: do we still need coding frameworks if AI writes the raw code?
For dropping them: Paul Ford's essay is titled "The Web Is More Than Enough," and AI now makes raw browser code cheap to produce. Against: Simon Willison still finds the framework version easier to read, which matters for anything you must maintain.
Signals to Track
Fake "thoughts" that hijack reasoning AI
Researchers fed reasoning models text styled like the models' own private thinking. In a test environment these "thought injections" succeeded up to 50% of the time, while the same request in a normal user voice never worked. If this plays out, AI agents that read web pages or emails will need defenses against text pretending to be their own thoughts.
Persuasive fake passages that fool AI fact-checkers
A framework called Debate to Deceive has AI agents argue against each other to produce convincing, coherent passages that trick AI fact-checkers. It beat earlier attacks on four standard fact-checking tests and slipped past most existing defenses. If this plays out, "the AI checked it" will mean less when you see it on a news or health claim.
Home robots that must guess why the smoke alarm went off
HomeLoop is a simulated home for testing robots that work with alarms, sensors and wearables. A smoke alarm might mean a pan about to catch fire, a fire already burning, normal cooking or a broken sensor, and each needs a different response. If this plays out, home robots will be judged on how they handle false alarms, not just chores.
AI companions where you decide what they remember
The Relic project keeps four things separate: what the system can observe, what researchers can review, what the companion remembers and what it can say. Sensitive safety signals go to human reviewers rather than into the companion's memory. If this plays out, companion apps could offer clear controls over what they keep about you.

One change vs. yesterday: Anthropic added Claude Fable 5.2 at $8 in and $40 out, 20% below Fable 5.1, with Claude Mythos 5.2 listed at the same price for approved organizations only. Fable 5.2 also has a faster mode at $16 and $80. Google's page now marks Gemini 2.5 Pro and 2.5 Flash as retired, with requests switched to newer models on December 1. Gemini 4 Carbon is still not on Google's developer pricing page, so we dropped it from the table. Mistral Large 4, OpenAI's long-prompt prices and some context sizes carry over from earlier checks.
What this means: Anthropic's flagship is now 20% cheaper than OpenAI's GPT-6 Astra on both input and output. For cheap everyday work, Claude Haiku 5.5 and GPT-6 Luna still tie at $0.10 in and $0.50 out, and Gemini 4 Argon doubles on December 1.
When Instruction Files Go Stale: Documentation Debt and Hidden Cost in Coding Agents
Key finding: With a stale test command, Claude Sonnet 5.5 needed about two extra tool calls per run, roughly a third more, and across 732 agent runs on 22 tasks no agent ever repaired the outdated file.
Why practitioners should care: Every outdated line in an agent instruction file is a small tax on every session, so review these files whenever you move folders or change commands. The study covered only three stale instructions and two models, and in two of the three cases the authors could not measure a cost difference.
