AI News Brief: TutorMoments is a newly released preview of an evaluation framework designed to test whether top large language models (LLMs) can strike the balance between stepping in to help and stepping back to let students think for themselves when acting as a tutor — one of the hardest trade-offs to get right in education. The evaluation uses a ‘replay’ format built on real transcripts from one-on-one math tutoring sessions in the US.

AI News Brief: Mysten Labs co-founder and CTO Sam Blackshear has announced he’s leaving to join Anthropic, where he’ll work on defensive security research. Mysten Labs, the team behind the Sui blockchain, was co-founded by Blackshear and four former Meta executives in September 2021; after his departure, the company’s technical vision will be led by co-founder and CEO Evan Cheng.

AI news flash: Tim Cook stated during what is likely his final earnings call as Apple CEO that the highly anticipated Siri AI upgrade may come with a paywall. He acknowledged the plan isn’t finalized, but the idea is to let users buy more Siri AI compute through their existing iCloud+ subscriptions, which currently provide expanded cloud storage. Cook said they think some users will want to use Siri AI heavily, so they’ll roll out some kind of upgrade on iCloud+ that lets users add on a higher-tier service bundle, and see how the market responds. He also stressed he’s quite excited about Siri AI’s current direction. This freemium-plus-paid-upgrade model mirrors what most AI players like Anthropic and OpenAI do.

AI News Brief: OpenAI recently announced research results on several long-standing open problems in mathematics and theoretical computer science, spanning three major areas: geometry, cryptography, and computational complexity theory. The company claims substantial progress in these fields, but the public summary doesn’t include specific proof procedures, algorithm details, or quantitative data — only the problem categories and academic scope touched by the research. Since the original summary is quite concise and doesn’t explain which models or methods were used to achieve these breakthroughs, nor provide verifiable technical metrics, we can’t offer deeper mechanistic analysis here…

AI news brief: Google launched a new feature on Thursday letting users generate fictional imagery directly in its satellite map app Google Earth through its AI image generator ‘Nano Banana 2’. Google said the feature was meant to let users ‘get creative’ in geographic scenes. The prompt-driven tool can overlay nearly any generated image onto real maps…

AI news flash: According to Nikkei data released during a July evening (Taiwan time), the four major US tech giants (Alphabet, Amazon, Microsoft, Meta) saw Q2 capital expenditures and other investments exceed their core operating cash flow by nearly $100 billion. This reflects growing market concerns about AI over-investment, with investors beginning to split these tech giants into two categories: those that can clearly demonstrate how AI directly contributes to revenue and profit growth, and those still stuck in the cash-burning infrastructure-building phase without a proven monetization path…

AI News Brief: SK Hynix reported earnings on Wednesday, with April–June net profit surging more than 13× year-over-year and operating margin reaching 76%, setting single-quarter records for revenue, operating profit, and net profit—stellar on paper. Yet the stock dipped after the release because operating profit still missed the analyst consensus, signaling that the market’s bar for AI chip stocks has clearly risen. SK Hynix rebounded strongly on Friday, but its market cap hasn’t reclaimed the $1 trillion threshold. Two months ago, fueled by aggressive US tech capex and the bet that AI is a long-term growth story, TSMC, Samsung Electronics, and SK Hynix all rallied, with market caps successively breaking $1 trillion—an Asian corporate milestone. Now the mood has shifted: investors who two months ago were scrambling for reasons to keep buying are now noticeably cautious, even as chip executives insist AI capex is a multi-year commitment. The article argues AI innovation rivals or even surpasses the internet in importance, but the current boom carries bubble-like risks reminiscent of the early-2000s dot-com era. The biggest difference: this rally is anchored in Asian tech companies, and a large number of Asian investors (including many retail players) have piled significant capital into related stocks—so if prices swing sharply, these same investors who benefited from the rally will be the first to take the hit.

AI News Brief: OpenAI recently disclosed and shut down a Cambodia-based scam operation that used ChatGPT to assist in investment fraud, romance scams (pig butchering), online gambling, and identity impersonation. OpenAI detected anomalous usage patterns from related accounts, classified them as cases of AI tool abuse for fraud, and suspended them per policy. Since the original summary is brief, no further details on account numbers, financial scale, victim range, or detection techniques were provided — see the original link for details.

AI news brief: Chinese optical communications supplier Zhongji Innolight listed on the Hong Kong Stock Exchange on July 30, with shares dropping on debut and breaking below the issue price right at open. The IPO raised HK$53.4 billion (about US$6.8 billion), making it the second-largest new listing in Asia this year. Zhongji Innolight is a key AI-related equipment supplier, primarily making optical communications components used for high-speed data transmission in data centers and AI servers…

AI News Brief: A Bitcoin (BTC) mining stock hedge fund is seeking capital amid an AI stock selloff, the UK’s Financial Times reports. Situational Awareness, a hedge fund founded in 2024 by former OpenAI researcher Leopold Aschenbrenner, has approached investors and lenders for fresh capital after suffering major losses during the recent AI stock selloff. According to the Wall Street Journal, the fund had roughly $20 billion in AUM as of June 8. Citing insiders and a July 24 investor letter, the FT noted the fund also offered some investors the option to buy back portfolio assets, though the size of losses and capital raised were not disclosed. The letter said the fund was up 439% net of fees through June, but the FT pointed out the fund used leverage to amplify positions, which magnified losses during the July AI crash. Aschenbrenner argued the selloff created attractive investment opportunities. Cointelegraph previously reported that the fund made heavy bets on power and data centers supporting AI, including Bitcoin miners pivoting to AI compute. March SEC filings showed the fund held about $1.11 billion across 7 Bitcoin mining stocks, including IREN, Core Scientific, Riot Platforms, and CleanSpark. Aschenbrenner published a series of AGI essays in mid-2024, predicting AGI machines would surpass college graduates’ capabilities by the end of the decade. Cointelegraph reached out to Situational Awareness for comment but had not received a response at the time of publication.
