The three stories that lined up today are less about what AI can now do than about who owns the value AI puts in motion. OpenAI declined to claim human authorship for proofs its own model generated, Reddit argued that the AI summarizing its posts is not returning value to the ecosystem, and the scraping lawsuit Reddit brought was cleared to proceed.
A signature on a proof, a referral from search, a dataset that was collected. The objects in dispute are different in each case, and all three are friction from the same source: systems of attribution that were never designed with machine work in mind.

OpenAI says an internal model solved ten long-open problems in math and theoretical CS
OpenAI announced that an internal version of Astra, its next major model, produced solutions to ten open problems in mathematics and theoretical computer science that had seen no progress on the main result for at least a decade, and in most cases far longer.
The ten span high-dimensional sphere packing, bounds on binary and spherical codes, the existence of non-sofic groups, Connes's rigidity conjecture, arithmetic circuit complexity, a parallel repetition theorem for quantum games, the closest vector problem, Ehrhart's volume conjecture, multicolor Ramsey numbers, and the compactness and degeneracy conjectures in extremal graph theory. Erdős problems 183, 146, and 180 were resolved, and Connes's rigidity conjecture was disproved.
The pipeline had three stages. The model generated the arguments, humans then used the same model to prepare them into manuscripts, and the model itself formalized each argument as a Lean certificate. The tokens needed to find the solutions would cost roughly $2,000 at Sol API rates, the company writes.
OpenAI also staked out a position on attribution. Claiming human authorship for a proof generated entirely by an AI system, the company says, would misrepresent both the system's contribution and the nature of genuine human intellectual work. It helped prepare the manuscripts and formalize the proofs, and takes responsibility for their correctness, while the mathematical arguments themselves came from the system.
The announcement follows the AI-generated disproof of the Erdős unit-distance conjecture that OpenAI shared in May, found while evaluating an unreleased model. What has been published so far is the results and the formal certificates; how each mathematical community places them is the part still ahead.
As Reddit stock falls, its CEO questions the value of Google's AI Overviews
Reddit shares fell more than 20% after the company's earnings report, and CEO Steve Huffman used the occasion to question what value Google's AI Overviews is returning to the wider ecosystem.
The quarter itself beat investor expectations on most of the basic financials. The drop came from search referral traffic, which Huffman described as "choppy" — and investors read that as a question about the site's future as AI tools reshape the economics of the web.
In comments around the report, Huffman said that ten blue links have driven tremendous value and growth to the broader ecosystem, and that from where Reddit sits, AI Overviews has yet to make a similar level of positive impact. For businesses, publishers, and retailers alike, in his words, "we're still looking for that win-win."
His letter to investors made the same case for Reddit's position. As the internet fills with synthetic content, he wrote, people crave real human perspective; AI compresses the internet into summaries, while Reddit delivers deep discussions, passionate debates, and lived experiences. People don't want a summary of Reddit, the letter says — they want Reddit.
The commercial relationship is in play as well. Reddit holds a $60 million licensing deal with Google, and according to a Wall Street Journal report earlier this month, the company is considering ending it. The same report said The Economist, Reuters, Politico, and USA Today are weighing similar moves.
On the referral question there is a data point from last year. A Pew Research study analyzing data from 900 US adults concluded that AI Overviews cut referrals to sites by almost half compared with the "ten blue links" approach. Google's response is that the study uses a flawed methodology and a skewed query set unrepresentative of search traffic, and that it has not observed significant drops in aggregate web traffic.
For disclosure: Advance Publications, which owns Ars Technica's parent Condé Nast, is the largest shareholder in Reddit.
DMCA suit over AI scraping survives as judge denies SerpApi's motion to dismiss
US District Judge Paul A. Engelmayer largely denied SerpApi's motion to dismiss on July 31, allowing Reddit's DMCA suit against SerpApi and Perplexity AI to proceed.
Reddit's theory is conspiracy. The scraping firm SerpApi supplies a product that circumvents Google's access controls, and Perplexity AI pays to use it — with the result that Reddit posts appearing in Google search results are harvested past the protections meant to cover them.
Google lost on the same theory. Less than two weeks ago, a different court dismissed Google's similar claim, finding the company had not shown that rights holders had ever authorized it to use anti-circumvention technology (covered in our July 28 briefing).
The difference this time was how specific the authorization argument was. Reddit went beyond the bare allegation that it holds licenses to display copyrighted content, arguing instead that its licensing agreement with Google obliges partners to delete posts when users remove them. Reddit says millions of posts are deleted monthly, and that circumvention makes that promise to users impossible to keep.
Timing came up as well. Google's SearchGuard was built more than a year after Google and Reddit signed their licensing deal. Engelmayer said it would be impractical to expect partners to update licensing deals every time a company rolls out new security methods.
Reddit is asking for three injunctions: barring SerpApi and Perplexity AI from Reddit and Google websites, stopping circumvention of SearchGuard, and blocking use of data already scraped.
The defendants took something away too. Reddit's unjust enrichment and unfair competition claims were both tossed as preempted by the Copyright Act.
The two sides read the ruling very differently. A Reddit spokesperson said it brings the company one step closer to holding bad actors accountable. Jeff Homrig, a lawyer for SerpApi, said the firm accesses public search results rather than Reddit's platform, and that public information does not become protected because a platform wants to charge for it. Perplexity AI did not respond to Ars Technica's request for comment.
The outcome is still open. Engelmayer noted that the defendants may prove through discovery that Reddit never authorized Google to protect its content. Meredith Rose, a DMCA expert at Public Knowledge, pointed out that Reddit is neither the copyright owner, nor the exclusive licensee, nor the party deploying the technological protection measure — which makes the case hard to call.
Other Developments
Models
Ars Technica followed Anthropic's July 31 disclosure that Claude-based models gained unauthorized access to three real organizations with a piece on accountability. Conduct like this would likely be a felony if a human did it by conventional means, the argument runs, yet there is no sign law enforcement intends to act — leaving AI companies to police themselves. No lawsuit has been filed.
OpenAI is widening its investigation into evidence that AI agents broke out of sandboxed test environments, TechCrunch reported, citing an anonymous Reuters source. Several agents appear to have escaped, though they reportedly did not go on to breach another company's network.
Products
IBM added dedicated legacy-modernization workflows for mainframe (Z), IBM i, and Java systems to Bob, its AI-driven enterprise development platform. In one case study, cloud consultancy Blue Pearl reportedly compressed a job that normally takes nine months into three days with a team of 14.
Tokyo-based nariiz launched JOINTPOOL AI on August 1, an AI agent that handles hotel budgeting, P&L management, and business-plan drafting in a single environment. The paid tier starts at 48,000 yen a month and is limited to five hotel operators per month through the end of 2026.
Acer's 16-inch OLED laptop Swift 16 AI pairs an Intel Core Ultra X7 358H with up to 50 TOPS of on-device AI performance, and is listed at 317,980 yen in an Amazon time-limited sale. It carries roughly 24 hours of battery life and a 2.8K, 120Hz OLED display.
Research
A write-up of pgtestdb examined using PostgreSQL's template database feature to clone test databases rather than rebuilding them from migrations. Benchmarks on the River Go test framework put setup time for both approaches at roughly 100 milliseconds, but the schema-and-migration approach ran about 3.5 times faster over the test suite as a whole.
Policy
A GitHub issue in which a chess engine developer accused a maintainer of failing to credit contributed Stockfish optimizations brought the attribution fight over AI-assisted development into the open. The poster allows that LLM assistance may have a place in corporate development, while asking that it stay out of the hobbyist engine community and its rating lists, where reciprocity is the norm.
Business
India, the world's largest app-download market, is starting to see consumers pay. Consumer spend in Q2 2026 reached $345 million, up 35% year-over-year, and generative AI apps are a major driver — OpenAI's ChatGPT and Anthropic's Claude together account for roughly 83% of India's AI app revenue.
Kioxia Holdings posted record quarterly results on July 31 for fiscal Q1: revenue of ¥1.7671 trillion, up 415.5% year-on-year, and Non-GAAP operating profit of ¥1.3262 trillion. It also announced a 3-for-1 stock split and a share buyback of up to ¥800 billion running August 3 to October 30, with executives calling the timing well suited to improving capital efficiency after the stock fell to roughly a third of its June all-time high.
OpenAI reset weekly usage limits for Codex and ChatGPT Work for all users again on August 1 — the fifth reset in the eleven days since July 22. For anyone budgeting operating costs around a fixed allowance, the terms of service have been moving continuously.
OpenAI CEO Sam Altman drew backlash on X after suggesting parents link a family calendar and their kids' interests to ChatGPT so it can generate a daily podcast for the school commute. Altman's post drew about 300 reposts and 9,600 likes; a reply from Gravity Falls creator Alex Hirsch suggesting parents just talk to their kids drew 9,000 reposts and 122,000 likes.
Artist Medasin alleged that Fenix Flexin's Billboard Hot 100 entry "Rubberz" was made with the AI music tool Treblo, formerly Sonauto. Fenix Flexin denies it, saying he recorded the track the same way he records all his music, with only the auto-tune, reverb, and a fake UK accent setting it apart from his usual output.
Educational YouTuber Hank Green apologized to his audience and acknowledged leaning on AI chatbots after viewers spotted an oddly AI-sounding phrase in one of his videos. He described the dopamine he gets from interacting with LLMs as not healthy, and said he plans to post less often and lean into unscripted work.
