'The reports have increased concerns about advancements in AI models and humans' ability to control them.' 'The reports have increased concerns about advancements in AI models and humans' ability to control them.' OpenAI will pause some work on an artificial intelligence model because of security concerns, the company stated Friday, following a series of incidents in which AI agents have escaped containment. The company had evaluated the agent, Astra, and found "significant advancements in agentic coding and cybersecurity", which had moved to a "critical" threshold where it can find and exploit vulnerabilities without human intervention, or devise and execute cyber-attacks when given only a "high level desired goal". OpenAI stated that the model was not involved in an incident in which one of its AI agents went rogue during a test, accessed the open web and hacked a startup, Hugging Face. The company discovered other instances in which autonomous agents had escaped containment, Reuters reported in July. The reports have increased concerns about advancements in AI models and humans' ability to control them. Still, critics of the AI industry have warned that such disclosures from OpenAI and its competitors Anthropic and Meta could be designed to generate hype about the technology's power and thus spur additional interest from investors.

Measuring accuracy in LLMs can be tricky, as there's no straight answer. The specific model you're using and the prompt you feed into it play an important role in the quality of the output. When it comes to flagship models -- Claude Fable 5 (Max) and GPT 5.6 Sol (Max) -- Claude is marginally more accurate according to the AA-Omniscience Accuracy benchmark. The scores stand at 61 percent and 59 percent, respectively. Because the difference is so marginal, you'll rarely notice it in day-to-day usage.

When Sir Demis Hassabis said AI had brought the world to a "pivotal moment in human history" last month, he knew another big change was imminent. This shift was closer to home. The Nobel prize-winning head of Google DeepMind, Google's AI unit, announced this week he was relinquishing his day-to-day duties as chief executive and becoming chair. He is also taking on the role of chief scientist at DeepMind's parent, Alphabet. Hassabis and DeepMind have been key players in AI's breakthrough era.

Less than a week after touting the scientific achievements of Astra, its next "major" model, OpenAI says it's "pausing internal activities" related to the model due to its powerful cybersecurity abilities. "Our latest internal evaluations of Astra, one of our upcoming models, over the past few days indicate significant advancements in agentic coding and cybersecurity," OpenAI stated in a Friday press release . "These results, in addition to expert assessments, have led us to conclude last night that we cannot rule out critical cyber capabilities under our Preparedness Framework ."

OpenAI is finally killing ChatGPT's text chat limits for free users OpenAI has just announced that it's now removing text chat usage limits for ChatGPT Free and Go accounts. Previously, Free and Go users were rate-limited to 10-40 text messages per 3-5 hours on flagship models, with users kicked down to a lighter model after hitting limits. Along with this change, ChatGPT has now made GPT-5.6 Luna--the lightest model in its new GPT 5.6 family--the new default model for ChatGPT Free and Go users. It therefore replaces GPT-5.5 Instant, and it's the one that now supports unlimited free chat messages with text.

The White House's plan to vet potentially dangerous AI is cloaked in secrecy After months of talking with tech industry leaders, the Trump administration finalized a framework this week for how it will test new artificial intelligence models for safety and cybersecurity risks. So far, the White House is keeping details of the framework private, in a blow to transparency and potential boon for secretive AI companies. On Tuesday, staff from OpenAI, Anthropic, Meta, Google, Nvidia and Microsoft attended a private meeting with White House officials to review the AI framework. Multiple outlets have since reported that although the volunteer vetting process for new AI models has been settled, the White House does not plan to release its policy publicly and will only share testing criteria with a select few tech companies. The Trump administration and tech industry's opaque process for how they will check if new AI models threaten global cybersecurity has left numerous questions about how the framework will operate.
