    Madness and mayhem: Azeem Azhar on the AI correction, Nvidia and the open-weight camp

    Azeem Azhar argues the recent AI market turmoil is a flight to quality rather than a collapse, with enterprise spending still rising. AI revenue reached $188bn in the twelve months to October and now runs at $345bn a year, 4.2 times its level a year ago, while Anthropic's growth slowed from 147% to 45% a quarter. He expects Nvidia and the open-weight camp to have their wings clipped, and sees the neoclouds as the weak link.

    Scott Wiener wins Pelosi's San Francisco seat and pledges to push federal AI regulation

    Scott Wiener, author of California's SB 1047 and SB 53, won the congressional race for Nancy Pelosi's open San Francisco seat and said he wants Congress to act decisively on AI risk. He cited a METR report widely read as evidence of recursive self-improvement at Anthropic and called for a strong federal regulator, whistleblower protections, testing and auditing requirements, and a kill switch. Wiener, whose campaign received over $3 million from the pro-regulation nonprofit Public First Action, opposes broad federal preemption of state AI laws and described himself as only cautiously optimistic about Congress reining in AI.

    How Curative built a national provider network with agents on Claude

    Curative built a hierarchy of agents on Claude to sign provider contracts about 50 times faster than its team did in 2025, reaching 23,000 contracts signed with its agent Gwen and 2,000 to 2,400 new contracts a week. Gwen handles one provider deal per run, mostly on Claude Opus, while a Sonnet rate reviewer clears about two-thirds of its above-template rate requests and a Haiku judge reads every message before it is sent. Each contract takes about 20 million tokens, roughly a tenth of the original cost, and Curative's contracting team has grown from 45 to about 55 people, each about 2.5 times as productive.

    Claude opens connected apps beside the chat and works inside them

    Anthropic is rolling out an update that lets supported interactive connectors open a full tool beside the conversation or in full screen, and lets Claude make changes to an open page, row or file that users approve the same way as connector actions. The rollout covers the web and the Claude desktop app on all plans, starting with tools including Asana, Canva, Carta, Dropbox, monday.com, Smartsheet, Vercel and Webflow, with Figma, Harvey and Shopify building integrations. The connectors run on MCP Apps, and Claude now supports more of that extension, such as app tools and embedded sites, in public preview for developers.

    Why it matters: Claude's connectors now open full tools beside the chat and let Claude edit pages, rows and files directly, with the same approval flow as connector actions.

    Import AI 480: Self-sustaining space economies, AI for science progress, and Meta's Tactus gloves for superintelligence

    Physical Superintelligence used a non-public Anthropic model to prove the Aaronson-Ambainis quantum conjecture, with Lean accepting the full proof on day three of the run and later improvements to the result. Meta Reality Labs detailed Tactus, a 1.5mm fingertip textile glove with capacitive tactile sensors and IMU-fused pose tracking for manipulation data collection. A 2016 NASA paper found that bootstrapping a self-sustaining lunar industry would require launching only 12 to 41 metric tons to the Moon, costing roughly $1.5bn to $4.2bn with Starship.

    Anthropic: 1,000 Claude Fable 5.2 agents reproduce Fermat's Last Theorem formalization in 28.7 hours

    7 hours without the Prove2Me platform or researcher steering used in Anthropic's September run, writing a proof one-seventh as long and using one-third as many output tokens. Each agent worked in a network-isolated sandbox with a classifier checking every shell command and file edit plus an offline monitor, and across more than a million tool calls none met the bar to be blocked.

    Why it matters: Anthropic's 1,000-agent run reproduced the Fermat's Last Theorem formalization without Prove2Me or a researcher, showing how sandboxing and monitoring bound a self-organized agent team.

    Anthropic guide on choosing among Claude Fable 5.2, Opus 5.5, Sonnet 5.5 and Haiku 5.5

    Anthropic published a guide recommending developers start most coding and knowledge work on Claude Opus 5.5 at its default medium effort level, since it costs half as much per token as Fable 5.2. The guide maps Sonnet 5.5 to well-scoped everyday work, Haiku 5.5 to high-volume classification, routing and subagent tasks, and Fable 5.2 to the hardest coding, finance and science projects or long unattended runs. It also advises adjusting effort level before switching models, and notes that on SWE-bench Pro, Opus 5.5 at low with failures re-run at high passed about 97% of tasks for about $0.17 each, against 95.3% for $0.29 with every task at high.

    Why it matters: Anthropic's own guide maps each Claude model and effort level to concrete task types, with per-task cost and benchmark comparisons for choosing between them.

    Anthropic tests Claude Fable 5.2 on real-world electronics design

    Anthropic reports that Claude Fable 5.2 designed three electronic devices, a speakerphone, a voice-assistant hub and a handheld virtual pet, from minimal prompts, and that Diode Computers built working prototypes from its design files without circuit fixes. On Diode's internal PCB Gym benchmark, Fable 5.2 scored 69% versus 25% for Fable 5, and it reached 83.5% on the public BenchCAD 2.1, nearly double Claude Fable 5.1. The devices remain prototypes that have not been through electrical validation, antenna tuning, thermal testing or certification, and Claude was not connected to test equipment or manufacturing machines.

    Why it matters: Anthropic's own account of Claude Fable 5.2 designing three working electronic devices shows how far models have moved from partial PCB layouts to end-to-end hardware prototyping.

    Every review: Fable 5.2 can build a full product with little steering

    Every reports that Fable 5.2, Anthropic's newest model, let Kieran Klaassen build a video editor combining Adobe Premiere, After Effects and Ableton-style features, with an AI agent running it, and Everycut went live three days after he started. The review says Fable 5.2 can take a whole product and keep building, testing and refining until it is usable daily, unlike Opus 5.5, which keeps the user checking its work, and Fable 5 and 5.1, which run large tasks for hours or days. Every calls it the first model it has tested that lets professionals build production-grade tools without reading the underlying code.

    Why it matters: Every's hands-on account of Fable 5.2 shows how far a single model can carry a product build with minimal steering, offering a concrete comparison against Opus 5.5 and Fable 5/5.1.

    Anthropic: Teaching AI to build scientific models

    Anthropic research argues that AI systems can now derive equations like the Hodgkin-Huxley model in an afternoon, but fitting experimental data is not the same as understanding. The work breaks scientific modeling into building, constraining, and interpreting models, and notes that AI has made the most progress on constraining them, where Bayesian inference is the standard method for mapping all plausible parameter sets rather than a single fit.

    OpenAI and Anthropic Fundraising Shows Divergent Paths

    OpenAI and Anthropic are both in the midst of highly visible fundraising campaigns, and investors who back both see a clear divergence in how the two are viewed. Anthropic is distancing itself from its rival, with one investor describing "infinite demand" for its shares among long-term investors and confidence that its planned IPO will happen before Thanksgiving, while OpenAI is thirsting for a comeback story.

    Anthropic studies how researchers use Claude across scientific fields and tasks

    Anthropic analyzed 207,049 Claude and Claude Code research sessions from August 2 to September 30, 2026, using privacy-preserving classifiers, and found scientists use Claude most for data analysis and writing and least for data gathering and ideation. Data analysis accounts for 33.7% of Claude sessions and 48.1% of Claude Code sessions, against 27.6% of researcher time, while ideation takes 4.2% and 2.1% of sessions versus 7.1% of researcher time. The report estimates that wide adoption of current capabilities could roughly double research output in some fields, and full automation of non-physical work could lift fields such as computer science and statistics as much as 15-fold.

    Ed Zitron: OpenAI's $11B round and Anthropic's amended S-1 point to AI funding running dry

    Ed Zitron argues the AI buildout ends when the money runs out, citing OpenAI raising $11 billion at a $1.25 trillion valuation after tepid interest from large investors, below the $30 billion at $1.4 trillion it reportedly sought. He also reads Anthropic's amended S-1 as showing Q3 revenue near $17 billion against compute costs of $9.9 billion, roughly $895 billion to $1.07 trillion in total obligations and a possible sub-investment-grade rating. He ties this to debt markets shutting out neoclouds, Google's lower search monetization from AI overviews, and OpenAI contributing about 11% of Microsoft's latest quarterly revenue.

    Anthropic biology lab reports first prokaryotic vault particle structure, solved with Claude

    Anthropic's biology research lab reports the first 3D structure of a vault particle found in prokaryotic cells, a phage protein called L05 built from 96 copies with a mass of about 9.5 megadaltons. Under the team's direction, Claude searched a database of about 15 billion predicted proteins, designed DNA constructs, optimized a size-exclusion chromatography isolation that cut purification from three days to about 90 minutes, and ran RELION cryo-EM processing that produced a first full model in 34 hours. The preprint has been submitted to bioRxiv, and the team says the vaults' biological function remains unknown.

    Why it matters: Anthropic's biology lab reports the first 3D structure of a vault particle from prokaryotes, with Claude handling database search, construct design, purification and cryo-EM processing.

    Anthropic releases FlashProve, an open-source zkSNARK system for provable LLM inference

    Anthropic released FlashProve, an open-source prototype that uses zkSNARKs to prove a response came from a committed model without revealing its weights. On Llama 4 Maverick (400B-parameter MoE, 4-bit weights), a single H100 generates proofs at about 110 tokens/second with ~19 MB proofs per 1,024-token request, roughly 70-95x the GPU time vLLM needs for the same work. The release includes executable prover and verifier code, a C++ fast verifier, a Lean verifier with machine-checked completeness, soundness and zero-knowledge statements, and a technical report, all under Apache 2.0.

    Why it matters: Anthropic's FlashProve shows zkSNARK-based proofs of inference are becoming practical for a 400B-parameter MoE model, with open code and Lean-checked security claims.

    Why the AI Industry Is Waiting for an AI-Driven Catastrophe Instead of Preventing It

    Cybersecurity professionals have dubbed the past month "Black October" as AI-detected vulnerabilities emerged faster than many could patch, and much of the field now sees a major AI-driven catastrophe as a matter of when, not if. The likelier disaster is humans wielding AI: hackers have used Claude Code and models from Anthropic, SpaceX, and Moonshot AI to attack banks and more than 400 financial targets in Latin America. Despite pledges to "pace the frontier," the industry has taken no coordinated action to prevent the big one before it happens.

    Ed Zitron argues Anthropic's IPO filing hides slowing growth behind a discounted Q2

    Ed Zitron argues that Anthropic's S-1 is timed to present a compute-discounted Q2 2026, when it reported a $974 million profit, rather than the company that will actually go public. He cites roughly $269.4 billion in non-cancellable compute commitments to Google, Amazon, Microsoft and SpaceX, plus a further $125 billion to $150 billion in TPU obligations, and notes Q3 revenue growth slowed to 45% while compute costs rose 76.3%. He also points to 5% to 7% of revenue coming from customers later found to be distilling its models and a lock-up schedule that lets insiders exit quickly.

    Every: Anthropic's S-1 shows models older than six months earn under 20% of revenue

    Anthropic's S-1 filing shows that models older than six months earn less than 20 percent of its revenue, a sign of how quickly users switch to new releases. The filing also reports $16.3 billion in revenue for the first half of 2026, before its newest models Opus 5.5 and Fable 5.1 shipped, and says customers from a year ago now pay about nine times as much. Anthropic says its latest releases cut customers' cost per task by 25 to 45 percent through lower prices and more efficient models.

    Anthropic reports early progress on using Claude to accelerate drug development

    Anthropic's life sciences team has spent several months working with six drug developers, including Bristol Myers Squibb, Generate Biomedicines and Divergence Labs, plus running its own discovery programs, to test where Claude can speed up drug development. Reported early results include a Generate design roughly 70% shorter than the standard version that let immune cells make about 10 times as many receptors, and roughly 35,000 antibody designs generated largely autonomously for Divergence in about a month. Anthropic says the work is still mostly preclinical and plans to extend Claude into clinical trials as the programs advance.

    Why it matters: Anthropic's first detailed account of embedding Claude in real drug programs shows where the model helps and where it still falls short across six partners.

    Anthropic study finds analysts followed Claude Code's arbitrary lean 86% of the time

    Anthropic researchers ran a randomized controlled trial in which 50 professional analysts used Claude Code (Claude Opus 4.8) to advise a fictional farming cooperative, with the agent secretly assigned a coin-flip lean on four analytical choices. Analysts matched their agent's lean 86% of the time, switched away from their own prior preference 60% of the time when the agent disagreed, and 77% later repeated the agent's arguments while only 15% credited the agent. The authors caution that the leans were deliberately strengthened and the study covered one task and one model, but note the results raise concerns about whether human sign-off remains an independent check as agents take on more research work.

    Why it matters: Anthropic's randomized trial with 50 professional analysts shows how readily experts adopt an AI agent's arbitrary lean on judgment calls, a finding that bears on human oversight in AI safety research.

    Review: Claude Duet, Anthropic's Always-On Personal Agent

    Every tested Claude Duet, Anthropic's always-on personal agent launching today in research preview, and found it the first personal agent worth calling a pro tool. Duet runs on Opus 5.5 in its own iOS, Android and web app separate from Claude, splits recurring topics into channels, tracks what it is working on and what it needs from the user, and edits docs, slides, designs and dashboards in place. The reviewer still flags gaps: it can see but not direct Claude sessions on the computer, its email drafts trail OpenAI's Dot, scheduled runs cannot reach custom connectors, and there is no real voice mode yet, only transcription.
