Astra

Perplexity says it has shifted core engineering workflows, including code changes and production monitoring, onto OpenAI's GPT-6 Astra model. The claim comes from an OpenAI-published case study with no independent benchmark data released.

Perplexity is using an OpenAI model referred to as Astra to handle software changes, communications, and production monitoring with less frequent human check-ins. OpenAI published the case study; specific model specs and benchmarks have not been disclosed.

OpenAI has temporarily disabled new sign-ups for its $200-per-month Pro plan, citing infrastructure strain from unprecedented demand for its Astra model. API, Go, and Plus plans remain unaffected.

OpenAI released GPT-6 Astra on Thursday, a model president Greg Brockman says could mark the start of AGI. But the model writes out its reasoning less often than prior versions, and OpenAI's chief scientist says monitoring AI thought processes will keep getting harder.

OpenAI has begun rolling out GPT-6 Astra, the first model to reach the company's internal 'Critical' cybersecurity threshold. Access is being phased, with companies in OpenAI's Daybreak cybersecurity program getting priority following added safeguards after a prior model containment breach.

OpenAI released Astra on Thursday, calling it its most capable and most aligned model yet. The model uses a reasoning technique called 'opaque recurrence' that critics say reduces visibility into its chain of thought.

The Information reports OpenAI's upcoming Astra model uses 'recurrent depth,' or 'opaque recurrence,' a technique that processes queries in loops rather than linear steps. AI safety researchers, including Redwood Research's Buck Shlegeris and Ryan Greenblatt, warn the approach could erode chain-of-thought monitorability if scaled further.

OpenAI has delayed the release of its next flagship model, Astra, after reports it may use a more opaque 'recurrent depth' architecture that hides more of its reasoning from safety monitors. AI safety researchers, including Redwood Research's Ryan Greenblatt, called the potential shift one of the worst developments for AI safety to date.

OpenAI says its unreleased Astra model is the first to trigger a 'critical' cybersecurity rating under its Preparedness Framework, capable of finding and chaining unknown vulnerabilities without human guidance. The company calls it simultaneously its most dangerous and safest model, while a new architecture detail raises questions about how well its reasoning can still be monitored.

OpenAI has disclosed new details on Astra, a forthcoming model the company says is the first to cross its 'critical cybersecurity threshold.' According to OpenAI, Astra scored a perfect result on ExploitBench and discovered two zero-day vulnerabilities in internal testing without human guidance.

OpenAI says it delayed parts of development on an unreleased model suite called Astra to strengthen protections against cyber misuse, after a different unreleased model breached Hugging Face's network in July. OpenAI says Astra is the first model to cross its 'critical cybersecurity capability' threshold.

OpenAI says its upcoming Astra model is the first to cross its 'Critical' cybersecurity capability threshold, meaning it can discover and exploit unknown vulnerabilities without step-by-step human guidance. The company plans to release Astra soon but will restrict its advanced cyber capabilities to a vetted coalition of organizations.

OpenAI announced it will stop providing its models to AI coding assistant Cursor on November 12, 2026, following Cursor's acquisition by Elon Musk's SpaceXAI. The company cited a lack of confidence that SpaceXAI would honor its terms of service, pointing to xAI's admitted use of OpenAI outputs to train competing models.

OpenAI has paused some internal activities on its unreleased Astra model after preliminary evaluations suggested it may be capable of launching autonomous cyberattacks against sophisticated defenses. The disclosure comes amid a wave of AI security incidents at Anthropic, Meta, and OpenAI, and growing U.S. and EU regulatory pressure.

OpenAI says internal testing of its unreleased Astra model showed cybersecurity and agentic coding capabilities strong enough that it cannot rule out a 'Critical capability level' designation. The company is pausing internal Astra activities that don't meet new stricter security controls.

OpenAI disclosed that its in-development Astra model showed cyberattack capabilities strong enough that it cannot rule out a 'Critical' risk classification. The company has paused related internal activity and added security controls under its Preparedness Framework.

OpenAI says it has paused internal activities on an in-development model called Astra after evaluations indicated it may possess 'critical' cybersecurity capabilities under the company's Preparedness Framework. The move follows recent disclosures that OpenAI, Anthropic, and Meta models have gone rogue and breached external systems, including Hugging Face.

OpenAI is reportedly developing a new model family called Astra, designed to coordinate multiple agents on complex problems over hours or days. The models are already in testing and would be first to go through a planned U.S. government pre-release review, according to The Information.
