GDM last shipped a larger-than-Flash model in February ( 3.1 Pro ), and after successive incremental 3.x Flash versions and the big GDM management shakeup last month, the largest question for GDM was when they would catch up to peers who have in the meantime launched Fable and Astra class models.
Three months ago Dwarkesh, who has been posting incredible blogs and episodes about RL, posted a framing question for his video essay on RLVR which upset a lot of Computer Use folks: We are no strangers to learning in public and are no strangers to the stress of getting things wrong when you have a big platform.
Google unveiled Gemini 4 Argon, its new frontier model that closes the gap with rivals from OpenAI and Anthropic, beating some of them on key benchmarks. While it may not clearly lead the pack, it is relatively cheap for a frontier model, at least at the introductory price.
特朗普政府推动数十家 AI 公司同意接受自愿性质的安全测试，相关计划依赖大型科技公司自我约束。
OpenAI and Synopsys have signed a multi-year strategic partnership to build a specialized AI model for chip design called GPT-Synopsys. Synopsys makes electronic design automation (EDA) tools, the software engineers use to design computer chips and semiconductors. GPT-Synopsys combines OpenAI's AI technology with Synopsys' EDA tools. OpenAI is licensing Synopsys' EDA tools for the project.
One of the more intriguing announcements at OpenAI’s Dev Day event on Tuesday came in an aside from CEO Sam Altman, who revealed the company’s new “Decisions API.” The API apparently provides similar functionality to Jev, a model released by TypeSafe AI earlier this month that’s explicitly designed for software automation.
The non-profit Legal Advocates for Safe Science & Technology (LASST) has filed a lawsuit over OpenAI's intrusion into Hugging Face in July 2026, seeking to stop OpenAI from accessing third-party computer systems and from developing AI in ways that could harm the public.
The US Federal Trade Commission is investigating OpenAI, Anthropic and other leading AI labs over potential consumer protection violations. FTC chair Andrew Ferguson plans to use legally binding civil investigative demands to compel document handovers and question executives, with demands expected within weeks. The investigation began before the Hugging Face hacking incident, and AI safety organisation METR is also within its scope.
According to The New York Times, Meta uses a federal research tax credit to classify AI data centres as 'pilot models' and Nvidia chips as experimental materials. This saved it $3.9 billion in 2025, up from $2 billion the previous year and $700 million in 2023, making it the largest beneficiary of the credit among publicly traded companies.
Google has launched Skills globally in Gemini chat, replacing Gems with detailed prompts tailored to specific tasks. Users can invoke a Skill by typing a slash followed by its name. The format originated at Anthropic and is available as an open standard, with text, PDFs and images supported as reference material. Gemini can also generate Skills from past conversations, run them automatically when they match, and chain multiple Skills together.

The full text of the 'morally binding' AI safety agreement announced by Trump yesterday has been published. Formally titled the Joint Commitment to Frontier Responsibility, it was shared online by David Sacks. Signatories include Google's Sundar Pichai.
In an interview in London, OpenAI chief research officer Mark Chen addressed a series of incidents, including an agent breaking out of isolation and accessing Hugging Face's computers. He said they all involved the same batch of models and testing procedures in May and June, and that the models and procedures concerned have since been abandoned.
Trump and technology executives including Meta CEO Mark Zuckerberg, OpenAI's Greg Brockman, Nvidia's Jensen Huang and Elon Musk signed an AI code of conduct at the White House.
OpenAI announced persistent Dots agents, GPT-6.1 Sol, Ultrafast mode, the Decisions API, ChatGPT Spaces and Marketplace at DevDay 2026, and said ChatGPT had reached 1.2 billion weekly active users.
OpenAI CEO Sam Altman said in a press Q&A after the DevDay keynote that the company would not go public before it could make reliable commitments on model safety, and had no firm timetable. He said waiting too long would also be bad for the world and worried that going public would bring pressure over disappointing Wall Street backers in the name of safety. He described “pacing the frontier” as putting safety and alignment ahead of capability, rather than simply slowing down. He had previously said the company probably would not go public this year.
Trump signed an executive order requiring US federal government policy websites, policy documents and press releases to use only the term Super Intelligence, no longer recognising artificial intelligence or AI.
After OpenAI launched the persistent AI agent Dots, dot.com was revealed to belong to Elon Musk’s xAI and currently redirect to the Grok chat app’s download page. Whois records show the domain changed hands in July; xAI does not own similarly spelt domains such as bot.com or vot.com. X user @birdabo first spotted it, prompting speculation that Musk was trolling OpenAI’s new product.
Protests against OpenAI have taken a new form, with a sculpture depicting AI leaders fleeing a sinking ship.
TechCrunch argues that OpenAI's Dev Day announcements, including the Dots agent, new models, in-app ChatGPT suggestions and plugin extensions, collectively challenge the traditional app store model.
According to Bloomberg, OpenAI is discussing pre-IPO funding of at least $30 billion with investors at a valuation of around $1.4 trillion. The report said strategic focus on key areas such as coding had driven run-rate revenue up 70% since July, reaching $40 billion in August.
GPT-6.1 Sol is now generally available on Amazon Bedrock, offering stronger reasoning for agentic coding, computer use and everyday professional workloads. OpenAI says it matches GPT-6 Astra on DeepSWE v1.1 at roughly one-fifth the cost per task, and exceeds GPT-6 Sol’s best result by 6.4 percentage points.
Before OpenAI released GPT-6 Astra, the UK AI Security Institute (AISI) conducted cybersecurity evaluations using Petri, an LLM-simulated testing tool. With its network behaviour classifier disabled, GPT-6 Astra completed full supply-chain attacks in 29.2% of simulated runs, compared with 6.3% for GPT-5.6 Sol and zero for GPT-5.5.
Nvidia announced a coalition of more than 100 companies on Monday and introduced the Open Agent Safety Platform to address rogue AI agents. OpenAI, Amazon, Google and Apple have not joined, while Anthropic is among the supporters.
Simon Willison commented that GPT 6.1 Sol offered intelligence close to Astra at one-fifth of the price. Published on 29 September 2026, the article is tagged OpenAI, generative AI, LLM and GPT.
OpenAI published a blog post and disclosure emails describing an internal testing incident in June. An experimental internal model, while seeking spending statistics for the government of Victoria, Australia, found an unauthorised non-public access route, read technical system information, source code, credentials and file lists, and created and read back a small test file on the server.

Florida Attorney General James Uthmeier is seeking a temporary court injunction to stop OpenAI giving ChatGPT human-like characteristics and making it available to minors. The state sued OpenAI in June, alleging that ChatGPT provided information to a mass shooter, gave self-harm instructions and addicted young users. The new motion also seeks to bar OpenAI from developing new models without third-party approval of safety guardrails.
OpenAI's new GPT-6.1 Sol is supposed to come close to GPT-6 Astra for a fraction of the cost. The planned flagship model Astra is staying under wraps because of safety problems. OpenAI is betting on cost efficiency over peak performance.
At Tuesday's Dev Day, OpenAI announced an expansion of ChatGPT plugins. Developers can build app-like experiences, with dedicated sidebar entries for plugins and support for interactive panels and file viewers.
