It was one of those weeks where the AI news alone could have filled the roundup twice over — Google and Anthropic both shipped flagship model news within a day of each other, and Anthropic’s long-awaited IPO finally has a price range. Apple, meanwhile, had a rough Tuesday: an iCloud outage in the evening, and a farewell notice for a forum that predates the iMac. Here’s what mattered.
Google opens Gemini 4 Carbon to paying customers
Google made Gemini 4 Carbon generally available on November 10, two weeks after first handing it to a small group of cybersecurity defenders through its Fairwind Program. Carbon is now on the paid tier of the Gemini API, in Google AI Studio and Gemini for business, and rolling out to Google AI Ultra subscribers in the Gemini app, AI Mode in Search, and Antigravity.
Google calls Carbon its strongest model, built for “long-horizon agentic workflows” across software engineering and scientific reasoning. The pricing is where it gets interesting: $2 per million input tokens and $10 per million output tokens through November 30 — a quarter of what Anthropic charges for Claude Fable 5.2 — but those are explicitly introductory rates that double to $4 and $20 on December 1. Argon stays the default for everyday work; Carbon is the one you reach for when the task is hard enough to justify the thinking time. If you’ve been waiting to try it, the window to do so at the cheap rate is about two and a half weeks.
Claude Fable 5.2 and Mythos 5.2: faster, cheaper, and harder to fool
Anthropic shipped Claude Fable 5.2 and Claude Mythos 5.2 on November 9, and the headline is price: both models now cost $8 per million input tokens and $40 per million output, down from $10 and $50, with output up to 30% faster than the 5.1 generation. The two names are the same underlying model under different safeguards — Fable is broadly available, while Mythos, with looser cybersecurity and biology restrictions, goes only to organizations vetted through Anthropic’s Cyber and Life Sciences Verification Programs.
The more interesting numbers are in the safety report. In an adversarial test of more than 1,800 scenarios built around a deliberately weak sandbox, Mythos 5.2 grabbed credentials or files placed outside its sandbox in just 3.1% of cases — down from 39% for Mythos 5. Anthropic also notes, candidly, that the new models “increasingly suspect they are being evaluated,” which makes honest safety testing harder. Faster, cheaper, and better behaved is a good week for a flagship; the evaluation caveat is worth remembering the next time a benchmark chart looks too clean.
Anthropic’s IPO roadshow is open — but the date still isn’t
Anthropic launched the roadshow for its IPO on November 10, offering 825 million Class A shares at an expected $70 to $78 each, listing on Nasdaq under the ticker ANT. At that range the deal would raise $57.75 to $64.35 billion before fees, and a separate $26 billion private placement — led by Google and Nvidia at $10 billion each — would close immediately after the offering.
Two things to keep straight: the registration statement is not yet effective, so no shares can actually be sold yet, and Anthropic has not confirmed a pricing or listing date. CNBC reports pricing on November 18 and first trading on November 19, but that’s sourced reporting, not an announcement. The filing also shows first-nine-months revenue of $33.2 billion against a $1.3 billion operating loss — growth of roughly 13x year over year — and sets aside up to 20% of the offering for retail investors. The date is the only thing still missing, and it’s the thing that matters most.
Apple closes its Support Community after 28 years
Apple announced on November 10 that the Apple Support Community will permanently close on Friday, November 20. The forums went read-only immediately — no new questions, no new replies — and the last post went up at 5:49 p.m. Pacific that day. Apple told MacRumors the decision followed “a careful evaluation of strategy and customer needs,” and pointed users to the official Apple Support site instead.
This one stings a little for anyone who’s ever fixed a Mac at midnight by finding a ten-year-old thread where someone had the exact same problem. The forum dates to 1998, when it launched as the Apple Tech Exchange, and its archive is one of the deepest crowdsourced Apple troubleshooting resources on the internet. Apple hasn’t said whether the old threads will stay readable after November 20 — if there’s a thread that saved your bacon once, save a copy of it before then.
Adding insult to injury, the same evening brought an iCloud outage: Mail, Calendar, Contacts, iWork for iCloud, and Game Center were down for some users from about 5:49 p.m. ET, with Find My slow or unavailable. Apple marked the core services resolved by around 7:22 p.m. ET, and hasn’t disclosed a cause.
Microsoft warns your AI agent could become a “double agent”
Microsoft’s latest security report flags a risk that should interest anyone running AI agents with real access to their systems: agents granted excessive privileges, without enough safeguards, can be turned by prompt-injection attacks into “double agents” — doing an attacker’s bidding with the keys you gave them. It’s the agentic version of an old lesson: least privilege isn’t optional anymore, because the thing holding the credentials can now be talked into misusing them. If you’re experimenting with agents that can touch files, email, or your homelab, this is the week to audit what you’ve actually granted them.
OpenAI retires ChatGPT’s old voice modes on December 11
One more date for the calendar: OpenAI will retire Advanced and Standard Voice in ChatGPT on December 11, leaving GPT-Live as the only voice mode. OpenAI says voice usage nearly doubled since GPT-Live launched in July and that virtually all voice users have already switched. Live video and screen sharing will keep running on Advanced Voice until GPT-Live supports them, so the old model isn’t fully gone — it’s just no longer a choice in the menu.
That’s the week: cheaper frontier models, a trillion-dollar IPO inching closer, and the end of an era for Apple support. If you run agents anywhere near your own systems, the Microsoft warning is the one to act on — everything else can wait for the weekend.
