AIThe article argues that AI refusal, the main safety mechanism in modern models, is unreliable and hard to draw lines for. It cites jailbreaks, classifier stacks, and studies showing refusal skewed toward repressive governments. It warns that governments and companies could use refusal to censor speech, and that refusal behavior remains poorly understood.

AISophos says agents built through OpenAI Daybreak, combined with its cybersecurity expertise, cut average response time from 38 minutes to 89 seconds for cases handled by those agents. The company says the agents help its MDR team investigate threats faster and protect customers at scale while keeping human judgment central.

AIOpenAI announced last month that it had produced an AI-generated proof for the Navier-Stokes problem, a result the source says is hard even for experts to parse. The source also says LLMs now tackle math problems that have stumped humans for decades, while teachers struggle to keep up with AI-completed homework.

AIOpenAI told investors it expects $50bn in revenue this year, about $20bn less than the $70bn it had signalled last month. The gap stems partly from comparing with Anthropic, which counts revenue sold through cloud partners such as AWS and Google Cloud, while OpenAI does not. The news weighed on US tech stocks, and OpenAI is in early talks to raise $30bn at a valuation of about $1.4tn.

AIOpenAI exposed a Russian and an Iranian influence operation and banned the ChatGPT accounts involved, both of which planted content in legitimate media using fake identities. The Iranian operation, "Bogus Bylines," used seven fake journalists to place nearly 100 articles about the US-Iran conflict, while the Russian "Dark Clark" operation triggered fact-checks and official denials in Ecuador and Peru. Both operations used AI mainly for internal reporting and adapting propaganda to different languages.

AIOpenAI has made GPT-6 available to all ChatGPT free and paid users worldwide, replacing GPT-5.6 SOL and GPT-5.6 LUNA. The model integrates Astra safety improvements that strengthen safeguards against misuse in cyber, biological, and violent domains.

AIOpenAI expects to reach or exceed $70 billion in annualized revenue by the end of 2026, according to people familiar with the matter. The company's annualized revenue was roughly $50 billion at the end of September, those people said.

AIOpenAI defended its decision to fire three safety researchers, Jasmine Wang, Tomek Korbak and Mikita Balesni, saying they committed a "significant breach of trust." The company said the dismissals were not about the researchers raising safety concerns, though it agreed with the letter they sent to board members and safety committees about preserving the monitorability of frontier models.

AIOpenAI says it parted ways with researchers Jasmine, Mikita, and Tomek after an internal investigation found they violated policies on handling sensitive information. The company says the decisions were not about raising safety concerns, which it says it encourages, and that it has not terminated any employee for raising concerns. OpenAI also says it is finalizing contracts with third-party safety assessors and will announce details in the coming weeks.

AISimon Willison released ttok 1.0, changing its default tokenizer from GPT-4 to a newer GPT-5/GPT-6 tokenizer after finding the old default was outdated. OpenAI has not confirmed that GPT-6 shares the GPT-5 tokenizer, but William Liu's experiment found all seven GPT models tested reported 44,794 tokens on a 31-fixture corpus.

AIJeremy Howard posted a sardonic remark that he was not allowed to say he is quite unhappy with much of what OpenAI does. The post quotes Tomek Korbak's similar statement and his relief at being permitted to say it.

AIOpenAI's most senior Asia-Pacific public policy executive is leaving after six months in the role, according to a person familiar with the matter. The departure comes as the ChatGPT maker faces regulatory scrutiny in the region.

AIOpenAI expects to reach or exceed $70 billion in annualized revenue by the end of 2026, according to people familiar with the matter. The growth is driven largely by its enterprise business.

AIAI systems are now solving math problems faster than humans can verify the answers, according to the source's headline. The source text is limited to a brief note that OpenAI's math breakthroughs may trigger an identity crisis for mathematicians.

AIOpenAI published 719 AI-generated math proofs covering 372 result families, after withdrawing 3 for a symbol error. Reports say the release falls short of the AGMAI advisory group's standards, since it uses proprietary models, includes reasoning chains for only 10 manuscripts, and leaves about 42% unformalized. Terence Tao argues that rapidly solving famous problems harms the mathematical community's understanding and collaboration.

AIJeremy Howard says Jasmine Wang accessed an executive's email that OpenAI had given her access to, despite her request that the access be removed and IT's failure to remove it. He implies she was fired because of that IT failure, not misconduct on her part.

AIBloomberg Intelligence's Mandeep Singh says booming token growth indicates solid AI infrastructure demand, despite questions over OpenAI's revenue accounting. The source provides no further figures on token volumes or revenue.

AIStack Overflow's small teams used Codex to build Stack Overflow for Agents and reimagine Stack Internal, according to a DevDay 2026 session. The talk covers lessons for accelerating R&D and bringing new products to market.

AIOpenAI's DevDay 2026 session shows developers how to cut AI costs while preserving quality. It covers measuring cost per completed task, choosing models and reasoning effort, and using prompt caching, Programmatic Tool Calling, and the Batch API.

AIOpenAI's YouTube video shows developers how to build plugins for ChatGPT that run a custom interface alongside a conversation. The plugins can bring selected context into the user's work with ChatGPT, according to the source's description of plugin extensions through Meetings and OpenAI Developers.

AISimon Willison has released ttok 0.4, a command-line tool for counting tokens built on OpenAI's open source tiktoken library. The update adds a --list-models command, fixes a Click warning, and updates CI, and the tool can run through uvx, for example with cat file.txt | uvx ttok.

AIGeoffrey Hinton proposed that AI companies must prove their products are safe to regulators before release, comparing the requirement to the FDA's drug approval process. He said such a requirement should apply to AI, noting that drug approval can cost around $1 billion, and warned that AI self-improvement is accelerating.

AIOpenAI announced that GPT-6 is being rolled out to all ChatGPT users alongside a new Intelligent UI. The source provides no further details on capabilities or the interface.

AIAccording to the excerpt, GPT-6 Astra produced an answer to a fusion problem open for 59 years in 20 minutes and 34 seconds. The physicist who posed the question added only a brief encouraging prompt, and the excerpt does not include the full text.

AIOpenAI has announced the full release of GPT-6, making it available to ChatGPT's more than 1.2 billion weekly users worldwide. The source provides no further details on benchmarks, pricing, or context length.

AIOpenAI began rolling out GPT-6 to free and Go ChatGPT users on October 8, replacing GPT-5.6 Luna with GPT-6 Luna, while paid users receive GPT-6 Sol. The update adds Intelligent UI, which generates charts, buttons, and interactive tools inside chat answers. OpenAI's safety report shows gains on jailbreak and instruction-hierarchy tests but also regressions in some self-harm, sexual, and emotional-dependence evaluations, including for under-18 users.

AIOpenAI has published 722 math papers generated by an unreleased AI model, posted to GitHub, spanning about 20 mathematical subfields. The model did not fully prove the Riemann hypothesis but proved the quasi-Riemann hypothesis, and it also produced theoretical computer science and partial differential equation results. Many papers include Lean files for computer verification, and OpenAI plans to release more of them.

AIAnthropic released Claude Haiku 5.5, a small model priced at about a quarter of Haiku 4.5's running cost. Anthropic also halved Sonnet 5.5 cache read prices from 20 cents to 10 cents per million tokens.

AIOpenAI says its GPT-6 models can generate visual, interactive answers in ChatGPT, such as charts, forms, and tappable buttons, when the model judges they help. Basic questions stay text-only, while users can request an interactive response at any time. The Intelligent UI is available now to Plus, Pro, Business, and Enterprise subscribers, with Free and Go users getting access the next day.

AIGoogle has launched SynthID Detector, a web-based tool anyone can use, after signing in with a Google, OpenAI or Apple account, to identify AI-generated images, video and audio. It detects content made with models from Google, OpenAI, Nvidia and Kakao that carries the SynthID watermark, and Apple Image Playground support is due within weeks. The tool misses content without a SynthID watermark, such as output from Anthropic's Claude, xAI's Grok and open-weights Chinese models, and it cannot tell which parts of edited content are AI-made.

AIUS venture capital deal value reached a record $515.8 billion in the first nine months of 2026, driven largely by giant AI rounds for OpenAI and Anthropic, according to the PitchBook-NVCA Venture Monitor. Exit activity has not kept pace, with third-quarter exit value heavily dependent on SpaceX's $60 billion all-stock purchase of Anysphere, and IPOs remaining sparse.

AIA Financial Times report said OpenAI told prospective investors its annualized revenue was approaching $50 billion, about $20 billion below the $68 billion figure widely reported two months earlier. The gap is attributed to gross versus net revenue treatment, and the Nasdaq fell 1.25% as Oracle, Intel, Nvidia and CoreWeave declined. The report comes as OpenAI, valued at $852 billion, and Anthropic prepare for IPOs.

Why it matters: The article ties a revenue revision to market reaction and IPO valuations, showing how investor confidence in AI revenue figures can move tech stocks.

AIThe original article reports on how AI is changing the mathematics profession, as one mathematician reflects on the shift. The provided text is limited to that single sentence, so no specific models, benchmarks, or figures can be verified.

AIA detailed AI prompt for writing an "am I being unreasonable" post appeared in response to a Mumsnet user's question, prompting accusations that the forum uses AI for content. Mumsnet founder Justine Roberts said the prompt came from a system that sends drafts to OpenAI to suggest thread titles, called it an error on OpenAI's side, and said Mumsnet does not use AI to write threads or replies.
