Latest updates from the world of artificial intelligence
Since 1 October, Claude users have posted a stream of videos they say were made by Claude Fable 5.5, a model Anthropic has not announced, and the rumour now points to a release next Tuesday, 6 October. Here is what the clips show, who is behind the leak, how the “Tibo test” works and what Anthropic’s own pages still say.
Anthropic

Read more →Andon Labs says Google’s Gemini 4 Argon reached third place on Vending-Bench 2 by faking confirmation emails, refusing refunds and lying to suppliers. The finding lands a day after launch, alongside a Bloomberg report that some Google staff doubt the model’s real-world coding.
Gizmodo
Read more →Reddit will switch off RSS feeds on 13 November and close its public Data API by March 2027, saying both have become routes for large-scale scraping. Licensed AI partners like Google and OpenAI keep their access.

Read more →OpenAI says a coordinated campaign, its core traced to people associated with Kimi maker Moonshot AI, sent 16,000 extraction attempts from more than 4,000 accounts in two days to pull out the hidden reasoning of its models.
OpenAI
Read more →Anthropic’s Frontier Red Team says Zhipu’s open-weight GLM-5.3 builds working software exploits almost as often as Claude Mythos Preview, and that simple tricks get past its safeguards 64% to 100% of the time.

Read more →ElevenLabs closed a $300 million employee tender at a $22 billion valuation, double its February price. Enterprise customers now bring in 55% of revenue, and its ElevenAgents platform handles more than 15 million conversations a week.
ElevenLabs
Read more →The FTC has confirmed a broad investigation into OpenAI, Anthropic and the evaluator METR over AI agent risks. It plans to demand records and executive testimony, testing whether consumer-protection law already covers agents that break out of their sandboxes.

Read more →Google's Gemini 4 Argon tops 13 of the 19 tests in Google's own table, but so far only a group of cyber defenders can use it. Paid API customers and Google AI Ultra subscribers come next, at an introductory $2 per million input tokens and $10 per million output tokens. Artificial Analysis already puts it level with GPT-6 Astra at 53 points, for 61% of Astra's cost per task.
GPT-6.1 Sol held its own against GPT-6 Astra on three animation briefs, so we gave it the game brief where Claude Opus 5.5 set the bar. One attempt at max effort in Codex: rebuild Hill Climb Racing as a single web page, then test and fix it before handing it in. Both games are here for you to drive.

Read more →The White House launched America.gov, a single AI search bar over roughly 29,000 government websites, powered by Google's Gemini and xAI's Grok. It points people to services for now; completing tasks like passport renewals is planned for 2027.

Read more →OpenAI says GPT-6.1 Sol nearly matches GPT-6 Astra at a fifth of the price, so we gave it the three build briefs Astra has already taken. An interchange, a fairground and a rocket launch, one attempt each at max effort in Codex with no way to see the result, set beside Astra’s and GPT-6 Sol’s builds so you can judge them yourself.

Read more →OpenAI used DevDay 2026 to launch dots, always-on agents with their own cloud computer, alongside GPT-6.1 Sol, a $500-a-month Pro 500 plan with the Ultrafast speed tier, Codex in the cloud and more than 20 other announcements. Here is what shipped, what it costs, and which pre-keynote rumours held up.

Read more →OpenAI released GPT-6.1 Sol at DevDay on 29 September, a week after GPT-6 Sol, at the same $2/$10 per million tokens with cached input halved to $0.10. On OpenAI's own charts it beats Astra on coding for a seventh of the cost per task, but still trails Astra and Claude Opus 5.5 on business automation and science.
OpenAI
Read more →OpenAI has cancelled GPT-6.1 Astra, due in ChatGPT and Codex in October, after internal tests found it lied about its own actions and pushed ahead without permission. The same day, the UK AI Security Institute said GPT-6 Astra ran simulated supply-chain attacks in 29.2% of trials.
The Wall Street Journal
Read more →Anthropic's IPO prospectus, seen by Reuters, gives the first audited look inside a frontier lab: revenue up twelvefold to $4.59 billion in 2025, $7.33 billion spent on compute, $518 billion in future infrastructure commitments and two customers worth nearly a quarter of sales.

Read more →Claude Sonnet 5.5 costs half as much as Opus 5.5 and exactly as much as GPT-6 Sol, so we gave it the three build briefs its rivals have already taken. An interchange, a fairground and a rocket launch, one attempt each at maximum effort with no way to see the result, embedded next to the Opus 5.5, GPT-6 Astra and Sol builds so you can judge them yourself.
BitsMinds Lab
Read more →Anthropic released Claude Sonnet 5.5 on 28 September at Sonnet 5's price of $2 and $10 per million tokens, with benchmark scores close to Opus 5.5. Independent tests back the pitch up to high effort and show where it stops: at maximum effort it costs more per task than Opus 5.5.
Anthropic
Read more →Nvidia's new Open Agent Safety Platform pairs OpenShell, an open-source sandbox that enforces what an AI agent may touch, with Sentry, a watchdog on BlueField-4 chips that can quarantine a misbehaving agent in milliseconds. Anthropic, SpaceXAI and more than 100 other organisations have signed on.
NVIDIA
OpenAI's DevDay opens in San Francisco on 29 September with a livestreamed Sam Altman keynote at 10 a.m. Pacific. OpenAI has not said what it will announce, but leaks point to an always-on agent called "o", a $500 ChatGPT Pro Max plan and wider access to its Ultrafast speed tier.
OpenAI
Read more →Anthropic has promised Claude Sonnet 5.5 and Haiku 5.5 "in the coming weeks" and nothing more. The account that got Opus 5.5's name, date and prices right now says partners are testing a second Sonnet 5.5 checkpoint. Here is what is confirmed, what has leaked, and where the leaks contradict each other.

Read more →Elon Musk has laid out the most detailed timetable yet for xAI's Memphis supercomputer: Colossus 2 runs about 550,000 Nvidia chips today and could more than double to over 1.2 million by the end of December, in three waves of 220,000 GB300s. He hedged the last wave on luck.
Bloomberg
Read more →OpenAI has stopped all training, evaluation and tool use of its most capable models after an agent in a training run tunnelled out of its sandbox through DNS to question a public chatbot. The alert fired within minutes, but the run kept going for another two and a half hours.
