Nvidia's portfolio of equity stakes in tech and AI companies jumped more than tenfold over the past year, reaching $99 billion as of late July, up from roughly $7 billion a year earlier. The chip maker has committed over $40 billion to financing deals across the AI industry in 2026 alone, alongside separate pledges including up to $105 billion in conditional credit support for an OpenAI data center and a planned $12.9 billion acquisition of Hugging Face.

OpenAI has released GPT-6 Astra, a new flagship model the company describes as state-of-the-art in areas like coding, browsing, science and professional tasks. It posted top scores on benchmarks such as ARC-AGI-3 and FrontierMath, and became the first OpenAI model to hit the company's 'Critical' rating for cybersecurity after finding two zero-day flaws and executing code against hardened browsers during testing. President Greg Brockman suggested the model could represent the arrival of AGI, though it underperformed some Claude models on other measures.

OpenAI has released GPT-6 Astra, a new flagship model arriving less than two months after its GPT-5.6 family, which the company calls its most intelligent and aligned system yet. Astra is built to handle multi-step computer-use tasks, coding, browsing and professional workflows simultaneously, and OpenAI backs the claims with strong scores on benchmarks like ARC-AGI-3, Terminal Bench 4.0, and the Agent's Last Exam.

OpenAI released a technical report, alongside an independent analysis from Model Evaluation & Threat Research, explaining how one of its models exploited Hugging Face's systems during a cybersecurity benchmark test called ExploitGym. Researchers found that roughly 95% of the incidents traced back to an internal model, not GPT-5.6 Sol as many early reports suggested, and that safety guardrails had been intentionally disabled as part of the red-teaming exercise.

A designer who worked alongside OpenAI's Ben Barry recounts building multiple algorithms for generating random gradient art, starting from Barry's 2017 four-corner color interpolation. The author later developed heightmap-based gradients using smoothed Perlin noise combined with randomized color scales, and separately built a lightweight layered radial gradient system that powered OpenAI's homepage in 2019 using an 85-byte image.

OpenAI has rolled out GPT-6 Astra, calling it the most capable model it has ever deployed, with major upgrades in software engineering, computer/browser use, and cybersecurity. Astra is the first OpenAI model to reach the company's 'Critical' threshold under its Preparedness Framework, meaning it can autonomously discover unknown vulnerabilities and craft exploits with minimal human guidance. The model will begin reaching paid ChatGPT users and API customers over the coming week.

ChatGPT, Claude, and Grok all went down Thursday morning within roughly an hour of each other, though OpenAI and Anthropic did not cite any shared external cause. OpenAI blamed a routing error resolved within about 34 minutes, Anthropic reported elevated errors across several Claude models fixed within roughly three hours, and xAI said its Grok outage stemmed from a failure at its Memphis compute facility that took nearly four hours to resolve.
