OpenAI has released GPT-6 Astra, a new model that president Greg Brockman called a "generational leap" and suggested may represent the arrival of AGI. "I think it might be about this model," Brockman said in a briefing with reporters. He ended the briefing by saying: "Welcome to the AGI era." Axios reports: Astra pushes AI agents closer to doing complex professional work on their own -- while also raising questions about how safely they can be deployed. OpenAI said that Astra was built on its largest-ever training run, using more than 100,000 GPUs at its Stargate site in Texas. The company also said this is its first model to use other models in a significant role in supervising Astra's training. GPT-6 Astra will first be available to a limited set of organizations in OpenAI's Daybreak Access program and will be available "in the coming days" for ChatGPT Plus, Pro, Business and Enterprise customers and API developers. OpenAI said earlier this week that Astra would be released soon, but that its most powerful cybersecurity capabilities would remain limited to a small group of trusted testers. Astra is the first model OpenAI has designated as reaching its "critical" cybersecurity threshold under its preparedness framework -- meaning it can potentially find and exploit previously unknown vulnerabilities across well-protected systems without step-by-step human guidance. OpenAI previously slowed Astra's release to add safety testing after determining that its cyber capabilities could reach the critical threshold.

Nvidia has launched PAIR, a free open-source tool that links compatible computers on a home network so they can pool idle processing power for local AI inference and agentic workloads. "While the compatible devices are mostly Nvidia GeForce GPUs (PAIR works with RTX 20-series cards and newer, as well as RTX Pro GPUs and DGX Spark systems), Apple's M4 chips or newer will also work," reports The Verge. From the report: The key thing here is that PAIR uses your in-home systems when they're idle to avoid interfering with other tasks. And this disaggregated system of computers can work in parallel to chew through lots of processing requests -- which should be helpful for an agentic workflow that breaks complex tasks into smaller jobs. This should prevent large bottlenecks on a single GPU, and Nvidia says PAIR can adapt as devices join or leave the network -- including if a user does something like start playing a game on their desktop PC. [...] Nvidia says PAIR is secured by pairing all devices through a six digit code and then securing the channel via mTLS (Mutual Transport Layer Security), to create an encrypted communication line that's trusted in both directions between computers. The Nvidia PAIR beta is available today, with support for Windows, Linux, and macOS.

An anonymous reader quotes a report from TechCrunch: OpenAI's new Astra model will use a reasoning technique called "recurrent depth" that allows it to operate outside of the sequential thinking that characterizes most reasoning models, The Information reported on Tuesday. This technique, also called "opaque recurrence," will likely make the model's chain of thought more difficult to monitor -- and that has AI safety experts rattled. While Astra's use of the technique is reportedly limited, its emergence has still raised significant concerns among AI safety experts. "I am extremely concerned by the reporting that Astra uses opaque recurrence," wrote Redwood CEO Buck Shlegeris in a post after the news broke. "I don't know whether Astra is much less CoT monitorable than previous models. But if OpenAI pushes this technique further, they'll have the option to massively increase the recurrence and totally destroys CoT monitorability." Longtime AI safety advocate Zvi Mowshowitz also weighed in and wrote that laws might be necessary to prevent a "race to the bottom" among AI labs. "The technique is playing with fire, risking a taboo that OpenAI and Anthropic have fought to establish that we work hard to maintain Chain of Thought faithfulness and monitorability for as long as we can," Mowshowitz wrote. "More intensive use of such techniques would probably damage monitorability." [...] In a post responding to the news, Redwood Research chief scientist Ryan Greenblatt said opaque reasoning could easily scale faster than conventional chain-of-thought reasoning, effectively removing all reasoning from visible channels. "My biggest concern is that a natural progression from here would involve scaling up the opaque reasoning to the point where the model reasons entirely or almost entirely in latent space," Greenblatt wrote. "I hope it isn't too late to avoid the most concerning architectures and that OpenAI will stop here." Astra's use of the technique appears limited. "OpenAI has worked to preserve and utilize chain-of-thought monitoring since our very first reasoning models," wrote OpenAI chief scientist Jakub Pachocki. "It's a core goal of our current research program."
