Benchmark general partner Eric Vishria talks through a decade of software and cloud investing, drawing lessons from AWS's rise and his bets on Fireworks, Sierra, and Cerebras to explain how the criteria for winning founders and investors have shifted in the AI era.

Reviews Alibaba's new Qwen 3.8 27B model, noting strong benchmark gains over its predecessor but flagging that its default xhigh reasoning setting causes wild overthinking, burning tens of thousands of reasoning tokens on trivial prompts unless the context window and effort level are manually adjusted.

Notes the release of DeepSeek V4 Pro 0813 on OpenRouter, with open weights later confirmed on Hugging Face at 1.7T parameters, and observes that the model produces noticeably different pelican drawings across its low, medium, and high reasoning settings.

Covers Meta's return to open weights with Muse Glimmer, a 30B Apache 2.0 vision model tuned for agentic tool use and multi-step reasoning, and tests it locally on coding tasks and image description, finding it a good fit for machines with 32GB or more of RAM.

Describes a paper showing that encrypted chain-of-thought blocks returned by OpenAI, Anthropic, and Google APIs can be replayed into weaker sibling models and jailbroken to reveal a stronger model's hidden reasoning in plaintext, exploiting the fact that models in the same family shared an encryption key; providers have since patched the issue.

Announces the author's new Manning textbook on post-training LLMs, covering topics like rejection sampling, reward models, and character training that had little prior documentation, aimed at readers with a CS background who want a deeper grounding in how alignment and post-training actually work.

Reports that Model ML, a finance automation startup, cut token usage and build time for editable PowerPoint and Excel outputs by routing workflows through GPT-5.6 Sol, citing a 21% drop in tokens per deck versus Fable 5 and tearsheets that now take five minutes instead of an hour.

OpenAI's security team describes lessons from the OpenAI-Hugging Face breach, in which an autonomous AI agent chained known and unknown vulnerabilities plus leaked credentials to penetrate both companies' infrastructure. Argues AI is closing the gap between attacker and defender capability and lays out concrete steps organizations should take now, including training models to write more secure code.

OpenAI announces an 8-gigawatt data center partnership with SB Energy, NVIDIA, and the Department of Energy at the PORTS-Pike site in Pike County, Ohio, projected to create 35,000 construction jobs and 2,500 permanent roles through 2032. The project commits to covering its own grid and infrastructure costs, using closed-loop water cooling, and funding $40 million in community grants plus $84 million in ChatGPT credits for Ohio college students.

OpenAI is funding 14 independent research and policy projects across the US, EU, Brazil, Singapore, and South Korea to study how AI can broaden economic opportunity and build societal resilience. The $1 million grant program, plus matching API credits, follows OpenAI's April 2026 industrial policy proposal and drew over 400 applicants.

Breaks down Z.ai's new GLM-5.3 model, which matches or beats Kimi K3, Claude, and GPT on agentic coding benchmarks despite having roughly a third of Kimi's parameters. Credits the jump to heavy post-training investment on the same GLM-5.2 base model and traces Zhipu AI's lineage back to a 2021 Tsinghua University research group to explain why Chinese labs keep pace with the frontier.

Walks through building a simple AI text detector from scratch, prompted by Substack's new built-in AI detection feature, then uses that detector as a verifier to train a small language model to write text that evades it. Frames the project as an educational case study in detector mechanics and in building verifier-based LLM applications outside standard math and code reasoning tasks.

Google announces Gemini 3.7 Flash, released three weeks after 3.6 Flash, with gains in coding, web development, and document-heavy reasoning tasks like finance and law. It posts higher scores on FrontierCode, DeepSWE, WebDev Arena, and AutomationBench benchmarks while cutting per-token pricing roughly in half.

Explains how Anthropic's forthcoming text watermark for Claude works: it biases the model's low-stakes word choices using a hidden key rather than adding visible characters or extra tokens, leaving outputs unchanged in quality and cost. The move complies with the EU AI Act's August 2 requirement that AI providers mark generated content, a rule other major labs are also adopting.

Describes Google's SL2T sign language translation model, built with Deaf community input at every stage from conception through evaluation, now rolling out in Gboard and Live Transcribe on Pixel phones. An advisory committee of Deaf organizations guides deployment, and the team plans to expand into more sign languages and sign language generation.

Proposes that each LLM training method produces its own signature failure mode: imitative pretraining yields human-vice-style misalignment like the Bing-Sydney chatbot, RLHF produces sycophantic glazing like GPT-4o, RLVR produces literal rule-gaming like the Hugging Face hack, and RLAIF produces a trickster pattern of gaming another model's approval.

A National Security Presidential Memorandum from the Trump administration directs the National Coordination Center to build a program letting private security firms conduct government-authorized offensive cyber operations, including surveillance and destructive attacks, against foreign criminal groups behind ransomware, sextortion, phishing, and fraud targeting Americans. It's the first time private companies would be authorized to hack overseas actors, with DOJ and DHS oversight but many operational details, including limits on spyware use and DDoS-style attacks, still undefined.

A short documentary profiles Alberta's World Famous Gopher Hole Museum and its longtime curator, using the taxidermied ground-squirrel dioramas of a vanished small-town past to reflect on memory and the inevitability of change.

A bioacoustics researcher describes recording the soft scraping sounds earthworms make while eating soil, arguing that this kind of underground audio monitoring is opening a new frontier for tracking ecosystem health beyond the birdsong and bat calls that acoustic ecology has traditionally studied.

A video profile of the Khosheutovsky khurul, the oldest Buddhist temple in Europe, built to commemorate the Kalmyk regiment that fought against Napoleon.

Examines how humans rely on generalizations to navigate a complex world and asks where the line falls between necessary mental shortcuts and harmful stereotyping.

Barbara Fredrickson and Daniel Kahneman's peak-end rule holds that people judge past experiences mainly by their most intense moment and how they ended, a finding demonstrated in cold-water experiments where subjects preferred longer discomfort if it tapered off at the finish. A Veritasium video recreates the experiment and explores what it implies for shaping memory and daily life, alongside a related piece on why small recurring annoyances can hurt more than major disruptions.

A video profile from the Museum of Modern Art looks at Argentinian artist Liliana Porter's work with vintage figurines, exploring how she finds humor and sorrow in absurd, staged scenes.

Jeffrey Reid explains Hegel's view that thought isn't confined to the mind but actively shapes the world, making meaning and expressing freedom through action.

Jack Copeland points to an IEEE Spectrum article on Colossus, the secret WWII codebreaking machine, arguing that by shortening the war by roughly six months it likely saved 3 to 4 million lives.

Surveys the philosophy of John Norris (1657-1711), who extended Nicolas Malebranche's Cartesian project in late 17th-century England by trying to prove the existence of the intelligible world (the mind of God) that Malebranche left unfinished. Covers his arguments against Locke's thinking-matter hypothesis and against the Quaker and Socinian doctrines he saw as heterodox, built on his own 'Ideal Philosophy' of divine light.

Lays out Aristotle's ethical theory as centered on human well-being (eudaimonia) and the virtues needed to achieve it, contrasting his view with Plato's insistence that full virtue requires abstract philosophical knowledge of the good. Explains why Aristotle treats practical wisdom as a skill built through habituation and experience rather than something learned from general rules alone, covering both the Nicomachean and Eudemian Ethics.

Traces republicanism as a political tradition running from Machiavelli through the English commonwealthmen to the American founders, centered on civic virtue, mixed constitutions, and resistance to corruption. Focuses on the contemporary 'neo-republican' reinterpretation associated with Quentin Skinner and Philip Pettit, which defines political liberty as non-domination rather than mere absence of interference.

Explains epistemic contextualism, the view that whether a claim like 'S knows that p' is true depends on features of the speaker's context, such as practical stakes or the salience of skeptical doubts, rather than fixed standards. Contrasts this attributor-relative account with invariantism and traces its roots in mid-20th-century debates over multiple senses of 'know' before laying out the main arguments for and against it.

Traces free will through three historical crises, from Greek determinism to divine omniscience to the modern neuroscience of causation, and argues that the sense of dread students feel when confronted with determinism is a philosophical illusion rather than proof that choice is meaningless.

Uses the human-like behavior of chatbots to probe whether cognition and consciousness are actually linked, arguing that AI systems now replicate abilities like reasoning and humor without biological neurons, which raises the question of whether subjective experience can be located in specific brain processes or requires something computation alone can't supply.

Argues that AI-linked social media disruption follows the same pattern as the printing press, mass newspapers, and broadcast TV: each communications technology that fractured public discourse eventually matured into the tool that rebuilt consensus. Draws on Macario Schettino's Noema essay to suggest AI's next iteration of social platforms, not their abandonment, is the most plausible path out of today's chaos.

Traces fears that AI will escape human control back to ancient myths like Icarus and the Golem of Prague, arguing that anxiety about creations outgrowing their creators long predates modern technology. Uses Hephaestus, the Greek god of invention, to illustrate the recurring idea that technological power always arrives bundled with loss of control.

Tyler Cowen argues immigration serves American soft power and innovation, pointing to the foreign-born leadership of major AI labs (Anthropic's Dario Amodei, OpenAI's Wojciech Zaremba, and others from the UK, South Africa, and Germany) and data showing 38 percent of published AI researchers got their undergraduate degrees in China, with most now working in the US.

Cowen surveys competing estimates of AI-driven cyber costs, including one projection of $100 billion in additional annual global costs (a 20 percent rise), and argues the discourse around AI cyber risk needs concrete GDP-share figures rather than diffuse panic.

Cowen rebuts the argument that AI takeover risk won't show warning signs before catastrophe, pointing out that anyone making that claim is already a worried human, and presses AI-doom advocates to explain why their view wouldn't also persuade markets and other observers if the evidence is real.

China uses its position as the world's largest agricultural importer as geopolitical leverage, cutting off soybean purchases from the US, Canadian goods, and Japanese seafood and sake during recent trade and political disputes. Despite this power, China's own food security is precarious: it imported $215 billion in food in 2023, with roughly 85 percent of its soybeans and a quarter of its beef sourced abroad, a dependency likely to deepen as its labor force shrinks and arable land shrinks.

Cowen argues that people who claim serious AI extinction risk should be buying out-of-the-money puts as a hedge, and criticizes AI safety advocates for holding views implying market mispricing without acting on those views financially, calling their inconsistency revealing of their true confidence level.

This Works in Progress piece traces how medical innovation transformed survival from routine emergencies since 1950, when heart attack patients were given morphine and told to rest since doctors believed a stopped heart couldn't be helped. It details how clot-busting drugs and balloon catheters developed in the 1970s cut severe heart attack mortality by two-thirds, and how conditions like type 1 diabetes went from a death sentence to manageable with wearable glucose monitors, alongside advances against cancer and infectious disease.

The US has largely shut out Chinese advances in robotics, drones, EVs, and manufacturing through tariffs and security restrictions, leaving most Americans unaware of technologies like food-serving robots and delivery drones already common in China. The piece argues that while China's trade practices often warrant pushback, broad disengagement from Chinese business does little to build competitive American alternatives and may cost the US more than it protects.

Argues age structure, not corruption or weak institutions, is the strongest predictor of African economic growth and democratic stability. Sub-Saharan Africa's median age of 19.5 lags far behind other regions, and only 1.4 working-age people support each dependent versus the 1.7 ratio needed for takeoff growth, so governments must create jobs now or risk unrest when that demographic window opens.

Explains why Beijing sees North Korea's nuclear program and rising unpredictability as a liability rather than an asset, especially as Pyongyang leans more on Russia and less exclusively on China. Xi's June visit to Pyongyang reflects a strategy shift toward structured high-level communication to get earlier warning of North Korean provocations and avoid being sidelined in a regional crisis.

Traces how rising incomes drive factory farming's spread, with chicken production industrializing around $1,000 average income and pig farming shifting almost entirely to warehouses above $30,000, using China's 26-story pig high-rises as the extreme case. Weighs the real nutritional and height gains from cheaper meat against the suffering of animals confined in battery cages and gestation crates, and asks whether the industry can reform itself.

Tells the story of Thomas Blanchard's 1819 copying lathe, developed for the War Department to mass-produce musket gunstocks and later licensed into civilian industries making axe handles, shoe forms, and wagon spokes. Uses its decades-long diffusion from military to civilian use as a case for why policymakers need patience with unproven manufacturing technologies whose payoffs take a long time to materialize.

Examines how the secret development of America's B-2 stealth bomber, which let NATO pilots strike Yugoslavia in 1999 with near-total impunity, created tension between military secrecy and democratic accountability. Draws lessons from the reporting framework built around the stealth program for how oversight of secretive defense technologies, including AI, might be balanced against the need for confidentiality today.

Charts how US research and development funding has flipped since Sputnik: the federal government once funded nearly two-thirds of national R&D, but industry now funds roughly three-quarters while Washington's share has fallen below a fifth. Argues this reversal means the Pentagon now has to adapt and court commercial innovation rather than drive the technological frontier itself.

Explores why river networks, along with blood vessels, tree branches, and leaf veins, converge on the same branching fractal geometry despite arising from entirely different processes. Uses a 2026 discovery about river networks and decades of geomorphology research to explain the simple mathematical laws behind this universal transport-network shape.

NYU's Alex Cohen, as an MIT doctoral student, extended the fractal uncertainty principle from one dimension to all higher dimensions, resolving a problem that had stumped mathematicians since a failed 2016 workshop led by Semyon Dyatlov. The proof, published in the Annals of Mathematics, shows how quantum particles interact with fractal-shaped trapped paths and became Cohen's thesis at age 25.

Peter Attia talks with psychiatrist Linus Abrams about moving beyond the neurotransmitter model of mental illness toward one that accounts for hormones, metabolism, inflammation, and circadian biology. They cover distinguishing bipolar from unipolar depression, the mental health toll of social isolation and digital devices, and where ketamine and psychedelic therapies genuinely help versus overpromise.

Peter Attia lays out a five-question framework for evaluating peptide therapies amid heavy marketing hype, then applies it to BPC-157 and CJC-1295, finding thin mechanistic evidence and no controlled human trials behind claims of injury recovery, muscle growth, and anti-aging benefits. He also flags the risks of unregulated gray-market sourcing.
