    Anthropic says AI cut its Claude port to AMD GPUs from months to three days

    Anthropic says it ported Claude to AMD GPUs in three days with almost no human intervention, using its frontier model Mythos to write nearly 100 percent of the kernels itself. Co-founder Tom Brown says Anthropic now trains and runs Claude across AWS Trainium, Google TPUs, Nvidia GPUs and AMD GPUs, treating them as one interchangeable compute pool. The figures come from an investor presentation and have not been independently verified; Anthropic cites three days versus the six to twelve months traditional engineering needs, measured on prompt processing with AMD MI355X GPUs.

    Why it matters: Anthropic's claim that its own model ported Claude to AMD GPUs in three days offers a concrete test of whether AI can loosen CUDA's grip on chip choice.

    Jensen Huang resigns as Nvidia CEO amid espionage scandal; $1.4 trillion in market value lost

    Jensen Huang resigned as Nvidia's CEO, president and board member effective immediately on November 12, 2026, after the Wall Street Journal reported the board planned to fire him over two extramarital affairs, one with a suspected Chinese spy. Nvidia has lost roughly $1.4 trillion in market value since an October 29 New York Times report on possible ties to Chinese intelligence, and CFO Colette Kress is taking over on an interim basis. Harvey C. Jones becomes the first independent board chair, while Huang's departure leaves no clear succession plan and could unsettle the alliance and guarantee structure built around him.

    Why it matters: Nvidia's abrupt leadership change and the $1.4 trillion market value loss raise questions about how deeply the AI chip supply chain depends on one person.

    Anthropic launches Claude Meetings in beta for Google Meet on Team and Enterprise plans

    Anthropic released Claude Meetings in beta, letting Claude join Google Meet calls as a visible participant that answers questions in chat, builds docs and whiteboards live, and writes notes and action items. Each meeting gets a page in claude.ai with the transcript, notes and artifacts, and by default Claude stays out of calls with external guests unless an admin allows it. The beta is rolling out on Team and Enterprise plans, is unavailable to some organizations including ZDR, HIPAA-ready and CMEK setups, and notes, transcripts and in-call answers are free during the beta.

    Why it matters: Anthropic's beta launch shows how a meeting agent can draft docs, pull connected-tool data and write notes inside a live call, with default rules for excluding external guests.

    Anthropic makes Claude Opus 5.5 the default model on Pro, Max, Ultra and Team plans

    Claude Opus 5.5 is now the default model in Claude on Pro, Max, Ultra and Team plans, and Anthropic recommends it as the daily driver for research, analysis and finished documents, decks and spreadsheets. Anthropic says Opus 5.5 at Medium effort matched or beat Opus 5 at High on its coding and knowledge-work evaluations, and in an internal merger-analysis test it finished in 63 minutes at half the cost of Opus 5 on the same task. The post also lists prompting changes for the new model, including dropping 'think hard' instructions, starting at Medium effort and attaching charts instead of retyping their values.

    Why it matters: Anthropic's own guide explains why Opus 5.5 is now the default for daily knowledge work and which prompting habits to drop for it.

    Anthropic IPO roadshow video details multi-chip Claude training and serving strategy

    Anthropic kicked off its IPO roadshow yesterday, and its roadshow video disclosed previously unreleased details about how the business works, including a section on compute strategy with co-founder Tom Brown. Brown said Anthropic trains and serves Claude across AWS Trainium, Google TPUs, NVIDIA GPUs and AMD GPUs, and that when the company began working with AMD GPUs this year, a system called Mythos got Claude running on AMD in three days with basically no human intervention, porting or writing almost 100% of the kernels. He also described compute multipliers as a second driver of compute advantage, saying each multiplier stacks on the ones before it and that Claude may eventually discover them entirely by itself.

    Why it matters: Anthropic's IPO roadshow video details its multi-chip training and serving strategy across four chip families, including a Claude-assisted AMD port completed in three days.

    Claude launches interactive connectors for Adobe, Atlassian and Box

    Claude now supports interactive connectors that open the full version of a tool inside Claude, so users can work in Adobe, Atlassian and Box alongside the conversation and either make changes themselves or ask Claude to make them. In the demo, Claude adds a summary to a launch plan in Confluence, applies a dither effect to a photo in Adobe, and checks a floor plan against a design standard in Box before saving the revision as a new file. The feature is rolling out on web and desktop.

    Why it matters: Interactive connectors let Claude operate inside Adobe, Atlassian and Box apps, showing how agent workflows move from chat into full third-party tools.

    Gary Marcus urges investors to reject Anthropic's IPO

    Gary Marcus argues against Anthropic's IPO, citing its reported target valuation of up to $1.4 trillion against a company that has never made a profit and carries nearly $900 billion in future liabilities. He points to Anthropic's amended S-1, which warns that costs will rise and losses will continue, and to revenue growth slowing from 147% in Q2 to 47% in Q3, as evidence that the trillion-dollar projections built on tokenmaxxing no longer hold.

    Why it matters: Gary Marcus uses Anthropic's IPO filing and slowing revenue growth to argue that the valuation rests on projections the company's own numbers no longer support.

    Anthropic releases Claude Fable 5.2 and Mythos 5.2, retaking the top LLM spot as its IPO roadshow begins

    Anthropic released Claude Fable 5.2 and Claude Mythos 5.2, which top most independent leaderboards, including Artificial Analysis Intelligence Index v5 at 65 and SemiAnalysis GDPx at 16.4%. Pricing drops 20% to $8/$40 per 1M input/output tokens, but SemiAnalysis reports cost per GDPx task rose from $67.16 to $88.15 because the model writes hundreds to thousands of test cases and spawns subagents to check its work. Multiple evals show the max effort level underperforming high, and Fable is capped at 50% of a weekly subscription limit.

    Why it matters: Anthropic releases Fable 5.2 and Mythos 5.2 with a 20% per-token price cut, yet independent evals show higher per-task cost and a max-effort setting that underperforms high.

    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 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.
