GPT-5.5's code execution score dropped sharply from 94.50 to 69.50 in today's Smoke evaluation, while material constraint rose from 76.00 to 100.00. The main index edged down from 86.18 to 83.23 after the two dimensions offset each other.
Grok 4's code execution score in today's Smoke evaluation plunged from 94.50 to 72.70, dragging the main leaderboard down 4.2 points, while its material constraint score rose to a perfect 100.00.
The 2026-09-01 YZ Index Smoke quick test covered 11 models, with GPT-o3 ranking first at 96.98 points. Notable shifts include gains for DeepSeek V4 Pro and Gemini 2.5 Pro, while Grok 4 and GPT-5.5 posted sharp drops in code execution.
The three-year-old startup says it reached $15 million in ARR and profitability before raising its latest $15 million round.
Nvidia invests $3.5 billion into Taiwanese chipmaker MediaTek. The deal shows how Nvidia plans to stay essential to AI infrastructure as Big Tech begins to build its own AI chips.
Explosive growth comes with a new regulatory burden in the European Union.
On August 31, 2026, the European Commission designated ChatGPT as a Very Large Online Search Engine under the Digital Services Act, with EU monthly active users of 159.1 million—far exceeding the 45 million threshold. OpenAI now faces the DSA's strictest compliance requirements, including systemic risk assessments, independent audits, and data sharing obligations.
Circleback is also introducing new pricing plans starting from $14 per month
SB Energy granted OpenAI warrants valued at $5.5 billion in exchange for a 20-year lease at a 10GW Stargate data center in Ohio, as disclosed in the company's draft IPO filing.
According to a report by The Information published on August 31, 2026, OpenAI has quietly assembled a massive fleet of Apple hardware—tens of thousands of Mac minis and Mac Studios—dedicated to reinforcement learning training and Computer-Use Agent development. Meanwhile, Anthropic, backed by Google and Amazon, has also been renting substantial Mac mini compute capacity through AWS for similar reinforcement learning tasks.
The US Commerce Department is drafting an unprecedented export control rule to bar Chinese AI firms from remotely accessing Nvidia's high-performance GPUs via data centers in Southeast Asia and beyond. The move escalates US restrictions from chip sales to compute access, but faces legal authority gaps and industry resistance.
Of the Glassdoor reviews from claims adjusters that mentioned AI, a staggering 98 percent were negative. “AI is just a tool,” one person tells WIRED. “It should never be given the keys.”
Interactive mobile "gizmos" are easy to make, hard to share outside Meta's platform.
Three US states have moved within six weeks to restrict AI data center expansion amid a 474 GW backlog of grid interconnection requests in Texas and more than $1 trillion in unfulfilled lease commitments from tech giants. The regulatory shift — from New York's statewide moratorium to Pennsylvania's legally binding GRID framework — reflects a structural struggle over who bears the costs of AI's energy and infrastructure demands.
On April 2, 2026, ten Chinese government departments jointly issued the "AI Science and Technology Ethics Review and Service Measures (Trial)," requiring ethics review before AI research begins — a world-first approach that marks China's shift from policy release to compliance enforcement in AI governance. The mechanism's timing fundamentally diverges from the EU AI Act's pre-market compliance model.
On August 29, 2026, the EU AI Office issued its first information requests to general-purpose AI model providers including OpenAI, Anthropic, and Google, covering model safety, independent external evaluation, post-deployment monitoring, and training data summary disclosure. The move marks the formal start of the mandatory enforcement phase.
The U.S. is shutting out more foreign-made drones and robots. China’s scale means the global competition may simply move elsewhere.
DeepSeek is close to completing a funding round of approximately 50 billion yuan at a valuation of about 500 billion yuan ($74 billion), expected to close by the end of August. The Hangzhou-based AI company has also initiated preparations for a 2027 STAR Market listing.
This week, 405 translation tasks were completed by 4 models. In a sampled blind comparison of 3 articles across multiple models, claude-sonnet-4.6 ranked highest overall with an average score of 9/10.
Grok 4.7's initial training is complete, but xAI has delayed its release to early September to inject SpaceX engineering data—including Starlink telemetry, rocket test logs, and internal engineering documents—into the model. With approximately 2.1 trillion parameters, Grok 4.7 marks a 40% scale increase over Grok 4.6.
