    The Coming Patent Storm in AI Hardware

    A Texas-based technology company filed patent infringement actions in May 2026 in Texas district courts, Delaware, and the ITC against Nvidia, SK Hynix, Kioxia, Corsair Gaming, and Western Digital over memory technologies, per Law360. The article argues that concentrated value in AI chips, shared engineering bottlenecks in HBM, chiplet interconnects, co-packaged optics, and cooling, and a maturing patent landscape are converging to make AI hardware the next major patent litigation front. It notes that the window before large operating companies build defensive moats through cross-licensing and inter partes review appears open now in HBM and CPO and is opening in chiplet interconnects.

    Engineering Fought Productivity Metrics. AI Ended the Fight

    Rising, variable AI token costs (Uber exhausting its 2026 budget in four months, Salesforce's reported ~$300M/year Anthropic bill) have ended engineering's exemption from productivity measurement, but DORA and SPACE show no single metric works, and 2025–2026 data finds AI raises throughput while also raising bugs, incidents and review time. The article argues for attributing AI activity to shipped work and outcomes, using cost per merged pull request, autonomy rate and token yield rate instead of token consumption, and treating committed AI configuration files as maintained code.

    Anthropic can already retrain Mythos with "a fraction of the compute originally needed," says former researcher Coxon

    Former OpenAI and Anthropic researcher Jacob Coxon says a slide from Anthropic's IPO roadshow was a major reason he left the company after about four months; the chart shows pre-training compute multiplier for code over time on a logarithmic y-axis, and Coxon says its steep climb points to accelerating algorithmic efficiency. He argues Anthropic's Mythos model was "not a one-time deviation, but a point on a superexponential," and that Anthropic could already retrain Mythos with a fraction of the compute originally needed. Coxon says algorithmic improvements are "on the verge of being automated" and wants frontier model development paused next year so competitors can catch up.

    Simple Puzzle Reveals AI's Jagged Intelligence

    An article describes training a GPT from scratch on a million solutions to the 15 puzzle, after which it solves 99.9 percent of randomly scrambled boards but fails on the easiest puzzles, including one that is already solved, while assigning its wrong moves over 97 percent probability. The author attributes this to AI emulating its training data through shortcuts rather than understanding, producing a "jagged" boundary where performance collapses outside the training distribution. The piece draws on Ilya Sutskever and Melanie Mitchell to argue that skill is not understanding and that AI can be confidently wrong.

    The avalanche that hit math is coming for AI development

    The author argues that AI is already accelerating frontier AI research—citing METR's finding that Anthropic's progress rate has doubled in a year, largely due to AI-assisted R&D—and that rapid gains in verifiable domains like mathematics suggest AIs could match the best human AI researchers within a couple of years, with a median estimate of 2028. He contends that AI research resembles the well-scoped, verifiable problems AIs excel at, so automating it could compress years of algorithmic progress into one, yielding either a "spark" or a "software-only singularity."

    Frontier AI takes only months to get 10 times cheaper

    Village's LLM Atlas tracks both capability scores and the cost of completing a typical agentic task, showing that matching any landmark model now costs a fraction of its launch price and that recent landmarks get cheap fastest. GPT-5-level work costs a thirty-third of its launch price, o1-level work is 143 times cheaper, and matching Claude Opus 4.6 is 51 times cheaper today. Levels set since o1 are falling 11 to 25 times a year, versus 3 to 5 times a year for GPT-4 and GPT-4o levels.

    Rethinking Memory for AI Inference

    Moving compute closer to memory can cut data movement, power consumption and latency, but different AI workloads need different approaches to memory architecture, interconnects and processing. Software support, standardization and thermal management remain major barriers to wider adoption, with processing-in-memory and near-memory processing still early despite efforts such as LPDDR6-PIM and compute on custom HBM base dies. The article surveys industry views on how edge inference, where models are known ahead of time, may benefit from ahead-of-time compilation and near-data compute.

    I Love AI

    In a personal essay, the author reflects on twenty years since leaving home to study computer science, explaining why AI drew them in: a field built on tackling problems computers cannot yet solve, where success gets absorbed into ordinary technology (the "AI Effect") and only the failures keep the AI label. They contrast that tradition of heuristics and resource-constrained approximation with today's generative AI, which they see as mostly scale-up engineering, and with papers whose contribution is simply asking an LLM to do something. They still call themselves an AI researcher "at heart," with a tongue-in-cheek "not that kind" disclaimer.

    Dispelling LTAP myths

    This post rebuts four common misconceptions about LTAP: that it is CDC replication, that a single copy forces slow lookups or scans, that open table formats mean eventual consistency, and that Postgres logical replication suffices. It argues Lakebase keeps one logical table with the lake as its durable tier and caches in front of it, so no layer adds a second catalog or source of truth. Each myth is traced to the same misunderstanding of treating every materialization of the data as a second database.

    What end-to-end AI systems mean for the future of automated driving

    In a Q&A, Aptiv vice president of engineering Guillermo Pita explains that end-to-end AI trains a single model to learn driving behavior directly from data rather than chaining separate perception, tracking, planning and control modules, producing more human-like driving but making explainability and debugging harder. He says data diversity, not sheer volume, is the key training challenge, with simulation and synthetic scenarios used to supplement rare events, and that centralized computing architectures fit the approach while concentrating more functionality on a single platform. Success, he argues, depends on advances in AI technology and on an organization's ability to translate millions of miles of driving experience into systems that perform consistently and safely.

    American Inequality and the Future of AI

    In a speech, Federal Reserve Governor Michael S. Barr reviews the latest Survey of Consumer Finances, which shows the top 10 percent of U.S. households hold nearly three-fourths of all wealth and the top 1 percent about one-third, while the bottom half hold only 2 percent. He traces how inequality widened and narrowed over the past century and examines how AI, as potentially capital-biased innovation, could further lower the labor share of national income—which fell to a record low of 52.8 percent in the second quarter of 2026—especially if market power concentrates among a few AI firms. Barr argues society should begin considering how to address these challenges while AI adoption is still in its early stages.

    Type 0.73: Earth on the Kardashev scale, and why AI is short of wire

    An essay applies Kardashev's power-based ranking of civilizations to Earth, which rates about Type 0.73 on Sagan's decimal version, and examines the energy demands of AI data centres. It argues that the current constraint is not generation but grid connections, transmission lines and chipmaking concentrated in Taiwan and the Netherlands, and it weighs Jevons's claim that efficiency raises rather than lowers total consumption.

    Discourse (forums) sees itself well positioned for the AI search era (vs Reddit)

    Discourse argues that Reddit's move toward a logged-in experience, driven by scraping concerns, falling search referrals and ad targeting, reflects an ad-based business model that its own forum customers don't share. It contends that for support forums and knowledge communities, an AI answer that resolves a user's problem without a click can still be a win, provided sources stay attributed and live links let people reach the full thread. Discourse says community operators, not a central platform, should control data boundaries, and that openness to AI retrieval is distinct from allowing bulk pre-training scrapes.

    Who Captures the Most Margin in AI?

    Tomasz Tunguz maps the AI value chain across five layers—power plant, data center operator, neocloud, inference vendor and AI application—and normalizes each to dollars per watt per year to compare gross profit pools, which at a 40% application gross margin split as power 3%, data center 5%, neocloud 28% before GPU depreciation, inference 24% and application 40%. He argues rising compute prices will test who holds pricing power, that applications will command varying pricing power based on ROI, and that vertical integration is already consolidating margin, citing CoreWeave's acquisitions of Weights & Biases, OpenPipe, Marimo and Monolith AI and Nebius spending more than $1b in 2026 on four companies.

    The global pledge to use AI for climate good is a cruel joke

    At COP31 in Antalya, Turkey, more than 190 countries were invited to endorse the Antalya Artificial Intelligence Pledge, which calls for clean-energy-powered data centers, internationally recognized standards, transparency reporting, and e-waste management, but states its objectives are "voluntary and non-prescriptive" and create no new obligations. The article notes the US, which has more data centers than any other country, has no official delegates at the summit after Donald Trump pulled the nation out of the global climate accord, and cites August research in a Nature journal finding AI causes more carbon emissions by boosting fossil fuel production than it avoids through renewable energy gains. The author concludes the pledge offers at best a placebo effect.

    Madness and mayhem

    Azeem says the past two weeks have been chaotic in tech, citing a correction in AI companies, the market shock of the Democrats' mid-term victory that gave the Nasdaq 100 its worst day since March 2020, and news that Jensen Huang has a relationship with a Chinese spy. He argues this is a flight to quality rather than a collapse: spending keeps rising, AI revenue reached $188bn in the twelve months to October and runs at $345bn a year, and Anthropic's growth falling to 45% a quarter puts it in line with the market. He expects Democrats to make data centers dearer, favoring hyperscalers, Nvidia and the open-weight camp to have their wings clipped, an Anthropic IPO at a sensible price to steady the sector, and neoclouds to be the weak link.

    Why Is AI Slop So Frustrating to Read?

    This piece argues that language models lag at writing because language is harder to optimize with straightforward rewards and less economically appealing short-term than capabilities like coding, and it focuses on workplace "slop" such as Slack messages and PR descriptions that readers cannot simply scroll past. It identifies three recurring faults—hidden characters and actions, vague wording, and empty statements with misplaced emphasis—and reports that AI samples show much higher rates of unclear communication than human writing across articles and coding discussions.

    I use 11.35B AI tokens a month. How many do you use?

    An analysis of 12,000 developers across 200 companies in Q1 2026 found that the median AI coding user consumes about 51 million tokens per month (roughly $52.38), while 90th-percentile users consume about 380 million tokens (roughly $691.14). Higher token usage correlates with more merged pull requests, but cost per PR rises from $0.28 in the lowest usage tier to $89.32 in the highest, and the median developer uses about 7 million tokens per PR versus roughly 69 million for the top decile. The author argues that broad, moderate adoption delivers more value than pushing a small group to extreme usage, and that an "agentic barrier" limits gains from simply increasing token consumption.

    The backlash about data centers might really just be about electricity

    Reporting from Data Center Alley in Ashburn, Virginia, the author argues that public opposition to data centers is driven more by electricity than by the culture war framing Big Tech favors, since facilities drawing 54 MW or more strain local grids and force new transmission costs onto utilities. Because AI-scale sites ideally need around 6,000 MW, companies are increasingly building behind-the-meter natural-gas turbines and diesel backup in rural areas, which still affects surrounding communities through air pollution and a lack of local say. The piece notes that industry insiders see their ambitions constrained less by public opposition than by a lack of electricity, and that future sites may go where few people can resist them.

    When Does the US Become a Net Importer of Tokens?

    With AI demand outpacing supply and domestic data center construction slowing, the US is projected to become a net importer of tokens between 2028 and 2030, depending on how many planned facilities are cancelled. Current systems plus new data centers can handle roughly 2.5x annual token growth, and imports begin by 2028 if 45% of planned projects fail to connect, by 2029 at 20% cancellations, or by 2030 even if every proposed facility is built on time. The piece notes that demand has been price-inelastic so far, with short-term GPU rental prices rising from $5 to more than $13 per hour over two quarters while buyers kept paying.

    Can AI self-improvement overcome diminishing returns?

    In a guest post for Noahpinion, the author argues that current evidence shows AI self-improvement loops would need to be roughly 5–10× stronger to sustain themselves, let alone produce a runaway intelligence explosion. OpenAI internal data shows models fully completing research tasks of only about 15 minutes at 80% success, far below benchmark and forecast horizons, while Anthropic estimates doubling overall AI progress would require roughly 40× productivity uplift. The author expects rapid AI progress and possible narrow superintelligence in highly verifiable domains, but sees no signs of accelerating returns and calls for better data.

    This post profiles Fabian Theis of Helmholtz Munich, whose lab has pushed algorithms for multi-scale, multi-modal, time-varying biological data and helped shape the Virtual Cell concept. It notes that a 2025 Arc Virtual Cell Challenge showed constant baselines often beat sophisticated perturbation-prediction models, though better-calibrated metrics let deep learning outperform the mean baseline, and that Theis argues existing datasets make perturbation prediction too easy a problem. It frames the roughly $1.8B Biohub commitment from Biohub, NIH, DOE, Google and Meta as funding large, high-precision, multi-scale data collection to predict evolution across molecules, cells, niches, tissues, organs and organisms.

    The Future of Knowledge Work with AI

    The article describes knowledge workers who now spend their days managing and reviewing the output of AI agent "swarms" that draft copy, write code, and produce strategy, and argues that when every company in an industry runs its thinking through the same small set of LLMs, competitive differentiation erodes and skills atrophy.

DeepSeek V4 Flash and Zhipu's GLM-5.2 once led large budget bands, but OpenAI's GPT-6 Luna and GPT-6.1 Terra and Anthropic's Claude Haiku 5.5 reclaimed them. The piece attributes the shift to closed labs distilling their own frontier models, releasing full model families, and serving inference at greater scale.

    Watts in Store for 2027 : The AI Ceiling

    Tomasz Tunguz argues the 2027 AI compute ceiling is about 80GW, roughly doubling all compute built in US history in twelve months, yet GPU hourly rental rates have already jumped from $3 to $12-13 and Anthropic's blended GPU-hour cost rose 82% in two quarters. He cites Brad Gerstner estimating 43GW coming online in 2027 against 38GW cumulative at end-2026, with 10-15GW of expected build possibly not coming online, and projects today's 38GW fleet earning about $140b while the 2027 additions deliver roughly $350b for nearly $500b total. Tunguz concludes that rising GPU prices may push foundation labs toward inference over training, make latency a release valve, encourage algorithmic innovation and harness efficiency, and force a reality check on vibe-coding economics.

    The Enterprise Case for Open-Weight Models on Databricks

    Databricks field engineers describe seven pressures pushing enterprises away from single frontier-model providers, including insufficient returns on AI spend, frequent ranking changes, guardrail refusals, shifting data-retention policies, governance demands, harness effects on performance, and open-weight models now benchmarking comparably to frontier models at lower cost. They present Unity Gateway as a unified API for routing and governing open-weight, frontier, and external models, citing internal data showing average unique models per customer rose from 4.2 to 7.1 since January, with roughly 40% open-weight. The post also notes GLM 5.2 reaching about 40% of open-weight tokens on Unity Gateway a month after launch and Databricks' $3 billion July raise, partly for GPU capacity to host open models.

    The author presents research notes from the Interconnects Dashboard, an aggregator of open model adoption and performance data, arguing that existing measurements of open model adoption are highly imprecise due to noisy platform metrics, startup marketing figures, and imperfect public evaluations. Using open model inference startups Baseten, Fireworks, and Together AI as bellwethers, along with OpenRouter's reported open model token share, the notes show near-exponential growth in disclosed token volume, with Fireworks reporting more than 40T tokens per day served to customers' customized models. The author overlays these figures against Google's reported platform and API token volumes from earnings reports to gauge how open model inference compares with closed and hyperscale providers.

    The author describes a study in which frontier models read neural network weights presented as plain text and reason about the behavior they encode, such as identifying a Pac-Man-playing network from its architecture and weights alone. He argues this is surprising because LLMs have no native channel for weights and no training data of this kind, and suggests it may reflect extreme generalization from program tracing and reinforcement learning. He notes that GPT-6 Astra, Opus 5.5 and Muse Spark 1.3 all identified Pac-Man, with Astra reporting 93% confidence.
