AI News Brief: SK Hynix’s AI chip boom benefits exporters like South Korea, but the US, despite investing hundreds of billions in AI infrastructure, sees limited economic growth. The report points out that while US data center construction pushes up semiconductor prices, most of the profits flow to chip exporters like SK Hynix rather than showing up in US GDP growth. In short, the AI infrastructure boom’s short-term lift to the US economy is weaker than expected, with upstream chip-exporting countries capturing the biggest dividends.

AI News Brief: OpenAI found that adjusting two API settings can nearly triple GPT-5.6’s scores on the ARC-AGI-3 benchmark while also improving efficiency. The first setting retains reasoning across multi-turn tasks so the model continues its reasoning chain instead of rethinking from scratch; the second enables compaction, which compresses prior reasoning before handing it to subsequent steps to slash context length and compute without losing key info. Combined, they show that managing a model’s memory and reasoning continuity is itself a direct lever for boosting both performance and cost — not just swapping models or scaling compute.

AI news brief: KOSPI triggered circuit breakers for two consecutive days, wiping $620 billion in market cap, mainly because SK Hynix’s Q2 earnings missed analyst expectations (despite record operating profit of 60.54 trillion KRW and 557% YoY growth, still below the 64 trillion KRW consensus). Stock fell another 4% that day, and combined with Tuesday’s drop, SK Hynix and Samsung Electronics together account for nearly half of the Korean index weight. The sell-off was amplified by single-stock leveraged ETFs approved in May…

AI news brief: Pangram, a New York startup focused on detecting AI-generated content, has raised $9M led by Menlo Ventures with participation from Haystack, ScOp, Script Capital, and Cadenza. They also launched Pangram 4 (text detection) and Pangram Image (image detection), claiming over 99% accuracy in detecting AI-assisted writing, human-AI hybrid content, and AI humanizer-rewritten text. The image detection model is currently research-preview only with wider release planned in coming weeks.

AI news brief: TSMC and South Korean chip stocks plunged on July 29, with SK Hynix shares falling despite reporting strong earnings — reflecting investor concerns about the rise of Chinese chipmakers outweighing fundamental positives. South Korea’s benchmark index accelerated its decline on Wednesday, breaking below a key technical indicator threshold and wiping out all the previous AI-driven rally gains. Market observers noted that profit-taking and position unwinding in AI-related trades…

AI News Brief: Nvidia announces plans to invest $1 billion in South Korean tech group Naver, marking a new phase in their collaboration on building global AI infrastructure. Under the agreement, Naver will leverage its partnership with Nvidia to target 200 megawatts (200MW) of data center capacity by 2028. The funds will go toward data center construction and expansion to support the massive compute demands of AI workloads…

AI News Brief: Core Scientific’s Q2 revenue more than doubled YoY from $78.6M to $164.2M, driven by rapid expansion of AI and HPC colocation business, while bitcoin mining’s share keeps shrinking. Colocation revenue surged from $10.6M to $136.7M YoY, lifting gross profit from $5M to $70M, but a $1.215B non-cash loss from warrant revaluation pushed the company to a $1.15B net loss.

AI News Brief: Crypto infrastructure companies are doubling down on Texas land acquisitions, driven by growing AI and HPC power demand. Galaxy Digital announced on Tuesday the purchase of a 500-acre site in McGregor, Texas, where it will build its second AI and HPC data center campus in the state, with initial planned power capacity of 74 MW to be expanded in phases. On the same day, Bitcoin miner MARA Holdings announced an acquisition agreement for a 1,200-acre site in Matagorda County with existing power access, supporting up to 2 GW of capacity, with plans to develop it for AI and HPC workloads while also using it as a Bitcoin mining base.

AI News Brief: Visa outlined its stablecoin strategy during the Q3 earnings call, emphasizing that it is investing across every layer of the stablecoin ecosystem. The company posted Q3 revenue of $11.6 billion, up 14% year-over-year, driven by double-digit growth in payments volume, cross-border volume, and processed transactions. Visa said it has invested across blockchain, issuance, wallets, infrastructure and orchestration, and applications, with progress this quarter in both the issuance and application layers. The company has joined the OpenStandard consortium, which plans to issue the OpenUSD stablecoin for global money movement. Visa’s stablecoin platform is designed to let partners settle with Visa in stablecoins, offering on-chain wallet-as-a-service infrastructure as well as the ability to move funds between fiat and stablecoins (starting with OpenUSD). The platform will also integrate with Pismo to support tokenized deposits for financial institutions, with plans to onboard third-party tokenized deposit infrastructure providers in the future. Visa also pointed to AI as another long-term growth area, viewing stablecoins and AI as complementary technologies: if stablecoins are reshaping the back end of commerce, AI is reshaping the front end, and agentic commerce will expand Visa’s addressable market and drive future growth. Cross-border volume grew 13% YoY (12% excluding intra-Europe), while processed transactions grew 10%.
