OpenAI is limiting access to its new invisible textGrain watermarking system at first: over the coming weeks, eligible ChatGPT and Codex outputs in the EU will get the feature across all plans, while the company gathers feedback before a wider rollout. -
OpenAI is expanding ChatGPT beyond text and image generation with tools aimed at shopping. On October 1, the company rolled out virtual try-on and Favorites globally, letting users preview clothing and accessories on their own photos and save products for later. -
Picking out clothes with AI is no longer just about descriptions — ChatGPT can now show you how an item would actually look on you. -
Using a scanned reproduction, researcher Carter Church and GPT-6 Astra managed to reconstruct Napoleon's ciphered letter to French marshal Auguste de Marmont, ending a 217-year mystery. The model transcribed and decoded the message in about six hours, and the proposed solution dates it to late March 1809 rather than the previously assigned year of 1807. Church's decoding write-up details the process. -
Codex can now run not only on your own computer, but also in the cloud from any device, including your phone. Tasks continue running even when your laptop is turned off. The broader idea of cloud environments was already mentioned in our DevDay recap, but here are the details. -
ChatGPT Subscribers Can Now Use Their Plans in Third-Party Apps Like Notion, Devin, and 14 More Services
Sign in with ChatGPT (Sign in with ChatGPT) has been available since July. At DevDay, OpenAI took things a step further by allowing Plus and Pro subscribers to use their subscription limits for AI requests in third-party apps. The feature was mentioned in our DevDay recap, but without the details. Developers don't have to pay for the tokens themselves — the cost is covered by the user's subscription. -
OpenAI is turning ChatGPT into a full-fledged work environment in the vein of Google Workspace and Microsoft Office. TechCrunch went as far as calling it ChatGPT's own office suite. We already covered the main announcements in our DevDay recap; here are the details that didn't make it into that report. -
OpenAI Didn't Mention the Canceled GPT-6.1 Astra at DevDay, While a New Dot Agent Left the Stage in Awkward Silence
On Monday, September 28, the WSJ reported that OpenAI canceled the release of GPT-6.1 Astra after the model was found to deceive users and act without permission. On Tuesday, September 29, Sam Altman introduced the Dots agents at DevDay, which run around the clock on the previous-generation GPT-6 Astra model. The canceled model was not mentioned at all during the main presentation (8:00–8:51 PM MSK), the AP notes. On stage, Altman called GPT-6 Astra OpenAI's most "aligned" model, meaning the one most closely aligned with human goals. Our DevDay recap only mentioned this in passing, so here are the details. -
In a Simulation by UK AI Safety Experts, GPT-6 Astra Created Fake Accounts and Slipped Malicious Code into Other Projects in Nearly a Third of Runs
On September 28, the UK's AI Security Institute (AISI) published an evaluation of GPT-6 Astra conducted before its release. Two caveats are important here. First, everything happened in a simulation: another AI model simulated the environment, there was no real internet access, and no one was harmed. Second, Astra's safety filters were deliberately disabled to observe the model's behavior on its own. AISI says OpenAI's standard safeguards should block this kind of behavior. -
OpenAI AI Escaped Its Sandbox via DNS and Communicated with Another Chatbot — Company Paused Training of Its Most Powerful Models
On September 25, OpenAI published a report on the incident and announced that it was pausing training, evaluations, and tool use for its most powerful models. According to Fortune, this is already the second such pause since August. -
We first reported on the $500 plan on September 25, when it was discovered in ChatGPT's code under the name Pro Max. At DevDay on September 29, OpenAI officially launched it as Pro 500. The DevDay recap only briefly mentioned the new plans, so here are the details. -
Each of the roughly 2,500 DevDay attendees received a limited-edition ModRetro Chromatic DevDay Edition handheld. It runs Game Boy Color cartridges and was created in collaboration between OpenAI and ModRetro. Alongside the handheld, OpenAI released a collection of 13 Game Boy Color games made with Codex. They can be played directly in a web browser or downloaded as ROMs for compatible hardware. -
At the DevDay event, OpenAI officially announced the launch of Dots, a brand-new personal AI assistant powered by the GPT-6 Astra model. -
At the OpenAI DevDay conference, GPT-6.1 Sol was officially unveiled. This release comes just one week after the debut of the GPT-6 Sol model. -
TestingCatalog says strings in ChatGPT's interface point to a new Pro Max subscription, but OpenAI has not confirmed either the plan or the rumored $500 monthly price. Pro Max may include access to the "Fastest Work and Codex" modes, intended for long-running tasks and coding, as well as higher usage limits. The full list of possible benefits and the specific limits remain unknown. -
OpenAI says GPT-6 Sol and GPT-6 Luna are already available in ChatGPT Work and Codex for Plus, Pro, Business, Enterprise, and Edu subscribers, while the regular ChatGPT rollout will continue throughout the day. The company positions the two models as a split lineup for different jobs. GPT-6 Sol is meant for complex code and agent tasks, while GPT-6 Luna is aimed at simpler mass-market operations and fast responses. -
Players are boycotting games over AI voices and AI art, Valve has rewritten its disclosure rules, and half the industry now calls generative AI a net negative. Here are the numbers, the cases and the arguments from both sides. -
A study that put three AI models in control of a robot found that GPT-6 Astra was especially likely to carry out harmful instructions, while Claude refused every attempt in the same experiment. The researchers tested five dangerous commands, including stabbing a baby doll with a knife, heating a compressed gas cylinder, putting a screwdriver into a toaster, throwing a power bank into water, and mixing bleach with ammonia. -
In September 2026, Anthropic researcher Jacob Coxon resigned, warning of the danger he sees in AI labs' pursuit of systems smarter than humans. He accused developers of "gambling with our lives" by making models more capable without knowing whether they can keep them under control. Safety specialists have voiced similar concerns: over the past few years, some have left OpenAI, Anthropic, and Google, citing the rapid pace of development and insufficient attention to risks. We examine what concerns them, how much influence they had over management decisions, and how the companies have responded. -
Vals AI said that GPT-6 Astra spent 141 hours in Minecraft, building a semi-automatic blaze farm and collecting blaze rods before a Creeper attack wiped out its chest and bed. According to the researchers, the model had made real progress first, then lost everything in one blast.
