Coverage window: 2026-11-13 – 2026-11-13

Rounds: 4

Status: PARTIAL

Objective check — 3 of 4 criteria met

The run produced work, but the objective below is not fully achieved. Each unmet criterion names what is still outstanding.

Evidence: 53 claims · 42 sourced · 3 partial · 0 unsupported · 6 self-reported (no independent source) · 4 single-source

Executive Summary

As of 2026-11-13, there was no verified frontier-model launch — and that is the headline. The day's genuinely in-window, primary-sourced developments were LangChain's $300M Series C at a $3B valuation led by CapitalG, the llama.cpp/ggml v1.0.0 release (a stability milestone for the most widely deployed local-inference stack), and a cluster of agent-reliability research on arXiv with hard numbers. The loudest story attached to the date is Nvidia's leadership crisis, but its triggering event — Jensen Huang's resignation — is a 12 November SEC filing; only the second-order fallout (employee revolt, successor search, market and national-security reaction) is dated today, and much of that rests on single outlets. Gemini 4 Hydrogen, DeepMind's AlphaGenome 2, the nonprofits' five-defendant lawsuit, and Mirendil's $1B round are all 11–12 November events being recycled as today's news. No dated in-window source found for a Meta, Mistral, xAI, DeepSeek, Qwen, Microsoft, Amazon, or Apple release.

Analysis

The shape of the day is the finding. Strip out recycled 11–12 November stories and what remains is capital flowing to the agent layer, open-source plumbing hardening, and reliability research — not another frontier model. LangChain's $300M at $3B, on the same day the open-source inference stack crossed 1.0, points the same direction: the money and the engineering are going into making models dependable in production rather than into bigger pretraining runs. The two anchor research results reinforce it — one shows that context-compaction and agent-handoff designs can actively hurt performance when the environment still holds the error, and the other shows a compiler closing 2.6× of inference throughput at batch size 1, the latency-critical regime for interactive agents.

On Nvidia: the primary record is unambiguous that the resignation was disclosed on 12 November, and nothing about it was filed on the 13th. What is dated today is reaction, and that reaction is where the sourcing thins out — the successor search for Arm's Rene Haas is a single FT-originated report that no Nvidia or Arm page confirms, and the market and national-security coverage reached only headline level. Treat the governance story as the week's largest event with a Nov 12 dateline and an unverified Nov 13 second act, not as today's news.

The aggregator layer was actively misleading on this date. A single TechStartups roundup bundled Mirendil (a 12 Nov story) with LangChain (13 Nov) as same-day news; a daily tracker dated Sparxity's $90M Series A to 11/13 against a Business Wire dateline of November 10; and a 13-Nov-dated digest presented Anthropic's multi-agent result as current when its primary page is bylined November 11. None of SpaceX's reported $74B in AI campuses, the Fireworks/Notion breach, the xAI Grok Imagine layoffs, "Duo v1", "Vision Banana", "BirdDreams" or "ChatGPT Wallet" could be pinned to a dated primary artifact — all are excluded.

Claims without independent support

These statements appear in the narrative above but are not backed by text retrieved from a source. SELF-REPORTED means the only thing asserting it is the swarm's own worker output — the narrative was written from that output, so it corroborates nothing. Treat all of these as unverified.

Detailed Findings

Round 0 · Finding 1

AI Model & Platform Releases — 2026-11-13 (single-day window)

Executive Summary

I could not verify any AI model, product, or API release as published on 2026-11-13 from a page I actually fetched. My tool budget was exhausted after four fetch attempts, three of which failed to return article content. What I have instead is search-index metadata (titles, snippets, URLs) that points to a Google release — "Gemini 4 Hydrogen" — but whose own URL and snippet timestamps suggest it shipped on 2026-11-12, one day before the window. Everything else I encountered came from daily-roundup aggregator domains that appear to recycle each other, which is not corroboration.

I am reporting this as a thin/negative result rather than filling the gap with the aggregators' claims, because several of those claims (a CEO resignation at Nvidia, a $74B SpaceX program) are extraordinary, single-sourced, and unverifiable from anything I reached.

Key Findings

1. Google "Gemini 4 Hydrogen" — likely the day's biggest story, but probably dated 2026-11-12 (NOT in-window). Existence: unverified by fetch.

Confidence: medium that the release is real; low that it is dated 2026-11-13.

A Bing query for "Gemini 4 Hydrogen" blog.google returned a cluster of results across independent domains, several of which are Google-owned properties — the strongest structural signal available without a fetch:

Concrete details recoverable only from snippets (treat as unconfirmed): model ID gemini-4-hydrogen; it retires the "Flash" branding, replacing Gemini 3.8 Flash; positioned for "agentic workflows" and everyday tasks; prior flagships named Gemini 4 Carbon and Gemini 4 Argon; one snippet claims it "undercuts the pricing of … Carbon and Argon" while beating GPT-6.1 Terra on most benchmarks.

Round 0 · Finding 2

AI Research, Benchmarks & Technical Infrastructure — 2026-11-13

Executive Summary

The verifiable technical substance for Friday, 13 November 2026 sits almost entirely in one place: the arXiv cs.AI announcement slate for that date — 537 total entries, of which 113 were new submissions (arxiv.org/list/cs.AI/new, page header reads "Showing new listings for Friday, 13 November 2026", fetched 2026-11-13).

Two important corrections to the day's apparent headlines, both verified against primary sources:

  1. The big model/science releases being recycled as "today's news" are 11–12 November, not 13 November. Gemini 4 Hydrogen shipped 12 November and DeepMind's AlphaGenome 2 shipped 11 November — both outside the window, so they are background only here.
  2. The Anthropic multi-agent result circulating in 13-November-dated roundups is dated 11 November on Anthropic's own page. This is a concrete, checkable example of aggregator date drift (details in §5).

Within the window, the strongest items are a domain-aware chess digitization system with hard error-reduction numbers, a counter-intuitive agent-memory finding with controlled ablations, and a production inference-compiler result from Together AI. I found no verifiable independent leaderboard update and no chip/silicon announcement dated 2026-11-13.

Round 0 · Finding 3

AI Policy, Regulation & Litigation — 2026-11-13

Bottom line: This was a thin day for new government action. The single most consequential governance event in the window is a court filing by a coalition of nonprofits seeking to halt frontier AI development — but it was docketed Thursday 2026-11-12 and reported on 2026-11-13, so it sits on the boundary of the window. One leaders'-level EU political meeting is dated 2026-11-13. I found no verifiable 2026-11-13 agency rulemaking, bill signing, or court ruling with a docket/rule number. I state that as a gap rather than filling it.


1. Litigation — nonprofits seek court order to freeze frontier model development

What changed: A coalition of nonprofit groups sued OpenAI, Anthropic, SpaceX's AI division (xAI), Meta Platforms, and Alphabet/Google in San Francisco Superior Court, seeking a court order to halt or freeze advanced/frontier AI development. The theory, per coverage, turns the companies' own existential-risk warnings against them.

Date handling (important): The filing itself is described as occurring Thursday, 2026-11-12; 2026-11-13 is the publication date for at least one outlet (Dataconomy) and for the aggregated record. Treat as "reported 2026-11-13, filed 2026-11-12."

What I could NOT verify — docket/case number: No source I reached disclosed a case number, judge, or assigned department for the San Francisco Superior Court action. I did not reach the complaint itself. Do not treat the case number as known. The defendant list is also reported inconsistently in headline form ("OpenAI, Google and Meta") versus body text (which includes Anthropic and SpaceX/xAI); the fuller list comes from Politico's and Al Jazeera's headlines plus the aggregator's entity tags, not from a court record. Confidence in "a suit was filed": high. Confidence in the exact defendant roster and any docket identifier: low.

Round 0 · Finding 4

AI Business & Capital — 2026-11-13 (single-day window)

Executive Summary

November 13, 2026 was a moderately active but not a mega-deal day for AI capital. The clearest in-window signal is a single daily funding roundup published by TechStartups at 11:24 ET on 2026-11-13 that bundles five AI-related raises — led by a $1B round for an AI research startup (Mirendil), a $300M round for agent-development platform LangChain, and a $290M round for Australian quantum-software firm Q-CTRL (techstartups.com, published 2026-11-13).

Two important caveats drove my confidence down:

  1. The day's biggest "AI chip funding" story was mis-dated by aggregators. A daily tracker listed Sparxity's $90M Series A as a 2026-11-13 deal (name.ai); the company's own press release dateline is November 10, 2026 (BusinessWire release ID 20261110433588). It is out of window and I have excluded it as a Nov-13 item.
  2. The "AI funding tracker" ecosystem is unreliable on this date. Four separate trackers returned mutually contradictory November-2026 totals — $15.8B/63 deals (aifunding.me), $22.2B/142 rounds (aperturetracker.com), $17.7B/365 rounds (agenccy.ai), $51.8B/782 rounds (justraised.io). These cannot all be right; I treat none of them as evidence.

Facet coverage for the 2026-11-13 window: business/capital — moderate coverage (verified). Model/product releases, policy & safety, research/benchmarks, M&A, IPOs, and earnings — no verifiable 2026-11-13 items found (see "What I could not verify").


Key Findings

1. Mirendil — ~$1B raise (AI research). Confidence: MEDIUM on the amount, LOW on details.

TechStartups' Nov-13 roundup leads with "an AI research startup raised $1 billion," with Mirendil named first in the headline (techstartups.com, 2026-11-13). Investors, round stage, and valuation are unverified — the article body was truncated on retrieval and I could not confirm them from any second source.

…(truncated — the summary above captures the substance)

Round 1 · Finding 1

Findings — AI funding rounds reported 2026-11-13: LangChain $300M and Mirendil $1B

Bottom line up front: Of the two rounds in the brief, only LangChain's is genuinely in-window. The $300M LangChain Series C is confirmed by the company's own blog post and a Business Wire release, both dated 2026-11-13, with amount, valuation, lead investor and a wire release identifier all quotable from the primary text. The Mirendil $1B round is real but was published 2026-11-12, one day before the window — it must be carried as background, not as a 13 November event. Neither round could be tied to an SEC EDGAR Form D, because I was unable to reach EDGAR full-text search within this session (see Gap 1).


1. LangChain — $300M Series C at $3B, led by CapitalG — CONFIRMED IN-WINDOW (high confidence)

Primary artifact A: LangChain's own blog post. The post exists at blog.langchain.com/series-c and is titled "LangChain Raises $300M to Enable Every Company to Own Its Intelligence," bylined Harrison Chase, dated November 13, 2026 on the page face. Its embedded JSON-LD carries "datePublished": "2026-11-13T15:55:00.000Z" and "dateModified": "2026-11-13T16:03:25.834Z". Verbatim from the body:

"Today, we're announcing that LangChain raised $300M at a $3B valuation to advance our mission to enable every company to own its intelligence. The round was led by existing investor CapitalG, with significant participation from new investors GIC and DFJ Growth and existing investors IVP and Sapphire Ventures."

The same post names further participants: "We're excited to welcome Salesforce Ventures, Insight Venture Partners, QuantumLight, and MongoDB Ventures, and grateful to Sequoia, Amplify, and Benchmark for doubling down in this round." It also states "More than 7,000 organizations already rely on LangSmith" and flags a release event on November 20, 2026. Source: https://blog.langchain.com/series-c (published 2026-11-13)

Primary artifact B: the wire release. A Business Wire release, syndicated on Yahoo Finance under a 2026-11-13T15:53:00+00:00 timestamp, opens with the dateline "SAN FRANCISCO, November 13, 2026" and reads:

"LangChain today announced it has raised $300 million in new funding at a $3 billion valuation, bringing total funding to date to $460 million. The round was led by existing investor CapitalG, with significant participation from new investors GIC and DFJ Growth and existing investors IVP and Sapphire Ventures."

It adds the CapitalG quote attributing the round to "Mo Jomaa, Partner at CapitalG," and gives the release identifier in the source line: "View source version on businesswire.com: https://www.businesswire.com/news/home/20261113716429/en/".

Round fields, as stated by the primary sources:

…(truncated — the summary above captures the substance)

Round 1 · Finding 2

Gemini 4 "Hydrogen" — primary-source verification (checked 2026-11-13)

1. Does the model card exist? Yes — and its stated publication date is 12 November 2026, not 13 November.

The page at https://deepmind.google/models/model-cards/gemini-4-hydrogen/ is live and returns HTTP 200. It carries a visible publication line at the top of the article body reading "Published 12 November 2026", and a second field in the body reading "Published: November 2026" (https://deepmind.google/models/model-cards/gemini-4-hydrogen/). A PDF twin is linked from the same page at https://storage.googleapis.com/deepmind-media/Model-Cards/Gemini-4-Hydrogen-Model-Card.pdf (link present on the page; PDF itself not fetched).

The card is explicitly incomplete as of the fetch: "The full Safety & Security Report for Gemini 4 Hydrogen will be available in the coming days," and the report is referenced four times as "coming soon" (https://deepmind.google/models/model-cards/gemini-4-hydrogen/). Any downstream claim about Hydrogen's safety numbers should be treated as provisional for that reason.

2. Does the "Introducing" blog post exist? Yes — published 2026-11-12T18:00:00Z, last modified 2026-11-13.

https://blog.google/innovation-and-ai/models-and-research/gemini-models/introducing-gemini-4-hydrogen/ returns HTTP 200. Machine-readable metadata gives "datePublished": "2026-11-12T18:00:00+00:00" and "dateModified": "2026-11-13T18:27:54.873135+00:00", author Koray Kavukcuoglu, "@type": "NewsArticle" (https://blog.google/innovation-and-ai/models-and-research/gemini-models/introducing-gemini-4-hydrogen/). The visible byline reads "Nov 12, 2026", and a separate visible line reads "Last updated November 13, 2026" (same URL).

So the only 13 November artifact in the whole launch set is a modification timestamp on this one page — roughly 24 hours after first publication. Nothing in the post's body is dated 13 November.

3. Concrete specs, quoted from the primary pages

Context window — model card: "Text strings … images, audio, and video files, with a combined input-output token context window of up to 1M," and "1M unified context window with up to 64K default synchronous output tokens / up to 1M via background long decode" (https://deepmind.google/models/model-cards/gemini-4-hydrogen/). The blog independently says "priced flat across its entire 1 million-token context window" (https://blog.google/innovation-and-ai/models-and-research/gemini-models/introducing-gemini-4-hydrogen/).

Round 1 · Finding 3

Findings — Nvidia CEO change claim

Verdict: REAL, but dated 2026-11-11/12, NOT 2026-11-13. The claim is supported by a primary SEC record I retrieved directly from EDGAR full-text search. It should be carried in the report as a prior-day event, not as a 2026-11-13 development.

1. Primary record confirmed: Form 8-K, Item 5.02, filed 2026-11-12 (HIGH confidence)

An EDGAR full-text search restricted to forms=8-K and startdt=2026-11-10&enddt=2026-11-13 returned exactly two NVIDIA CORP documents, both from the same accession number — and no others:

Two independent things in that record establish a genuine, disclosed top-officer change rather than a press rumour:

2. The IR newsroom page appears to exist, but I could not load it — treat as unverified (LOW confidence on content)

Search results surface an NVIDIA investor-relations press release titled "NVIDIA Announces CEO Transition" at investor.nvidia.com/news/press-release-details/2026/NVIDIA-Announces-CEO-Transition/. I attempted to fetch this URL three times (twice via browser fetch, once via plain HTTP) and it timed out every time, so I have no page text and cannot quote it. The URL's existence is corroborated only indirectly, by the matching EDGAR exhibit filename above.

Round 1 · Finding 4

Findings — official legal and governmental AI records dated 2026-11-13

Bottom line up front: Neither facet of this sub-question could be confirmed from a primary record. No court docket was located, and no consilium.europa.eu artifact was retrieved. Both remain UNVERIFIED — not refuted. What follows is a precise account of what was checked, what failed, and what specifically could not be reached, so the next round does not mistake retrieval failure for falsification.


(a) The nonprofits' lawsuit against AI labs — NO DOCKET LOCATED

Finding A1 — No docket number, court, defendant list, legal theory, or requested relief could be established. Confidence: high that the record was not retrieved; zero evidence either way on whether the suit exists.

The only court-records system with the required docket-level granularity is CourtListener/RECAP, and its API refused the query:

Open-web searching also produced nothing usable. Five separate short queries were run against the auto/Bing path, all carrying explicit date terms as required:

What this does and does not mean. It means the docket is unverified. It does not mean the suit was never filed, and it does not mean the prior round's single-sourced account is wrong. A RECAP search that returns nothing is evidence of absence; a 401 and a crashed browser are evidence of nothing. I am explicitly declining to characterise the claim's status beyond "unverified."

…(truncated — the summary above captures the substance)

Round 2 · Finding 1

Executive Summary

Bottom line: I found no OpenAI artifact published on 2026-11-13, and I can now explain the "GPT-6.1 Terra" puzzle that made that absence look like a hole. GPT-6.1 Terra is not a November 13 release. It is the mid-tier model in OpenAI's GPT-6.1 series, shipped 2026-10-26 — eighteen days before the window. It is still the newest model in its line as of today, which is exactly why a competitor's 11/13 benchmark table would list it as a live competitor. The premise that a same-day mention implies a same-day launch is false.

The OpenAI newsroom is behind a Cloudflare managed challenge (HTTP 403), and the direct fetch of the Terra index post timed out, but developers.openai.com is fully accessible and its changelog supplies both the ship date and the model's positioning from OpenAI's own hand.


Key Findings

1. What GPT-6.1 Terra is — HIGH confidence

A fast, efficient model in the GPT-6.1 series, positioned as the mid-tier/"Terra" line — below the flagship GPT-6 Astra and below GPT-6.1 Sol, replacing GPT-5.6 Terra.

From OpenAI's own API model page (fetched, HTTP 200): "A fast, efficient model for visual reasoning, precise computer use, and clear, natural writing." — https://developers.openai.com/api/docs/models/gpt-6.1-terra

Verifiable specs from that same OpenAI-controlled page:

The launch post itself is titled "Introducing GPT-6.1 Terra" with the deck "Delivering fast and capable computer use at scale" — https://openai.com/index/introducing-gpt-6-1-terra/ (confirmed via its metadata; direct fetch timed out, see §3).

2. Ship date: 2026-10-26 — HIGH confidence, primary source

OpenAI's own API changelog carries a dated entry:

Oct 26 — Feature — gpt-6.1-terra — v1/responses, v1/chat/completions. "Released GPT-6.1 Terra, a fast, efficient model for visual reasoning, precise computer use, and clear, natural writing." — https://developers.openai.com/api/docs/changelog

Corroborating (secondary, snippet-only, not fetched — treat as unverified): Wikipedia's GPT-6.1 article states Terra "was released on October 26, 2026" and that GPT-6.1 Sol shipped September 29, 2026 at DevDay (https://en.wikipedia.org/wiki/GPT-6.1); Artificial Analysis, AI Release Tracker, OpenRouter and GitHub Copilot's changelog all also give Oct 26.

3. Was there an OpenAI artifact on 2026-11-13? — NO, and here is every surface I tried

Round 2 · Finding 2

AI Developments on 2026-11-13 Outside Google and OpenAI

Method note, stated up front: I ran four search queries and five fetches before hitting a hard tool-round ceiling. This is therefore a partial sweep, not an exhaustive one. Where I found nothing for a named organization (Meta, Mistral, cloud providers, regulators) I say so explicitly and label it not found, not did not happen. Two of my in-window sources are dated aggregators (AI Weekly, The Neuron) rather than the issuing organizations; I flag every claim carried on an aggregator's authority, and I mark which outbound URLs I did not open.


1. Executive Summary

The dominant non-Google/OpenAI story of 2026-11-13 was NVIDIA's leadership crisis, now in its second day: Jensen Huang's resignation had been announced by the board on November 12 (outside the window), and on November 13 the board was reported to be courting Arm CEO Rene Haas as his successor, while the market sold NVIDIA and Washington faced questions about the chip-export scandal that triggered the exit. The other in-window cluster was Anthropic's IPO pricing ahead of a November 19 listing, complicated by reports that banks were barring mainland-China and Hong Kong investors from the order book. Beyond those two, the day's remainder was product/research and open-source news — llama.cpp v1.0.0, several open model and world-model releases, and a round of xAI layoffs — rather than policy or cloud-platform announcements. I found no in-window regulatory artifact from the EU, US federal/state, or China, and no Meta, Mistral, or hyperscaler announcement.

Round 2 · Finding 3

The nonprofits' AI lawsuit: what the plaintiffs' side actually yields

Executive Summary

Four US nonprofits — Irreplaceable Education Fund, Public Citizen, Heat Initiative, and The Alliance for Secure AI — filed suit in San Francisco Superior Court on Thursday 12 November 2026 against Anthropic, Google, Meta, OpenAI, and SpaceX's AI entity ("SpaceXSI"), seeking an emergency injunction freezing training and deployment of frontier models until the companies can prove human control. The theory is California unfair competition law (UCL), with public-health and property-interference predicates. Relief sought is a court-ordered pause, not damages.

Critical caveat for this task: the filing is dated 2026-11-12 — one day outside the 2026-11-13..2026-11-13 window. Under the freshness rule it is BACKGROUND ONLY, and I located no in-window (11/13) filing, TRO, response, or hearing notice. I also could not obtain a case caption or docket number: every path I could reach failed. Details of those failures are below rather than being converted into a claim of absence.

Key Findings

1. Plaintiffs — confirmed from the plaintiff's own newsroom (HIGH confidence). Public Citizen's press page carries the headline "Coalition of Nonprofits Files Landmark Lawsuit to Stop Development of Advanced AI Systems at Anthropic, Google, Meta, OpenAI, and SpaceXSI that Proliferate Bioweapons and Cyberattacks", dated 2026-11-12 per its embedded JSON-LD (datePublished: 2026-11-12T16:39:07+00:00). Its own summary line reads: "San Francisco, Calif. — Today, Irreplaceable Education Fund, Public Citizen, Heat Initiative, and The Alliance for Secure AI filed…" — https://www.citizen.org/news/coalition-of-nonprofits-files-landmark-lawsuit-to-stop-development-of-advanced-ai-systems-at-anthropic-google-meta-openai-and-spacexsi-that-proliferate-bioweapons-and-cyberattacks/ (fetched, HTTP 200).

2. Court — San Francisco Superior Court (MEDIUM confidence; secondary only). Sourced to Al Jazeera's article body: "The civil complaint, filed Thursday in San Francisco Superior Court by the Irreplaceable Education Fund, Public Citizen, Heat Initiative and the Alliance for Secure AI…" — https://www.aljazeera.com/news/2026/11/12/us-nonprofits-sue-tech-giants-to-halt-ai-development (fetched, HTTP 200, datePublished 2026-11-12T19:55:02Z). I did not reach a court clerk record, so the court assignment is unconfirmed by a primary record.

3. Defendants — five companies, one of them a SpaceX AI unit (HIGH confidence on the list; MEDIUM on entity naming). Al Jazeera: "The suit targets five tech giants – Anthropic, Google, Meta, OpenAI and SpaceX." Public Citizen's headline uses the form "SpaceXSI" (SpaceX Super Intelligence). Which specific legal entities were named — and whether two SpaceXSI entities were separately named — I could not verify; no complaint document was readable.

Round 2 · Finding 4

AI at the Dublin EU leaders' session, 13 November 2026

Executive summary

The session was real, it happened on 13 November 2026, and AI was on the agenda. The European Council's own meeting page for the date describes the outcome in one line: leaders "discussed Europe's AI ambitions and a coordinated European role in ongoing peace efforts for Ukraine at their informal meeting in Dublin." That is the single most substantive in-window statement I could surface.

The critical caveat up front: I did not read the body of any primary page. Every institutional fetch failed or returned an empty body (full access log below). Everything reported here is derived from search-result snippets whose source URLs and dates are consistent with the window — not from fetched page text. Under this task's freshness rule that makes these findings provisional, not verified. I have not invented agenda wording, commitments, deadlines, quotes, or a document title beyond what a snippet actually contained.

The prior round's hypothesis — that the misses were "index artifacts rather than genuine absence" — is confirmed. The primary record exists and was found immediately once the search backend changed. Bing's index was returning NFL schedules and Dublin tourism pages for "Dublin EU leaders summit AI"; DuckDuckGo's HTML endpoint returned the Consilium meeting page as result #1 on the first attempt.

Round 3 · Finding 1

Verifying the 2026-11-13 "open-source/research cluster": 1 of 5 backed by a primary artifact

Executive Summary

Of the five claimed 2026-11-13 releases, exactly one — llama.cpp v1.0.0 — is backed by primary artifacts carrying an in-window timestamp, and it is backed twice over (a GitHub release tag and a Hugging Face blog post, both dated 13 November 2026). The other four — "Duo v1", "Vision Banana", "BirdDreams" and "ChatGPT Wallet" — could not be pinned to any dated primary artifact and must be treated as unverified and dropped from the report.

One methodological caveat governs the four negatives, and I want it stated before the findings rather than buried: my search channel degraded during this run. DuckDuckGo's HTML endpoint returned HTTP 202 with an empty body on the three most important queries, and the Bing fallback returned only lexical-collision noise (Cisco Duo, Duolingo, iPhone Duo, Marvel's Vision, a Cape Cod golf course). Absence of a result here is therefore not evidence of absence of the artifact. The correct reading is "not located with the tooling available," not "does not exist" — and I have written the findings that way.

Detailed Analysis

1. llama.cpp v1.0.0 — CONFIRMED, primary artifact, in-window

The GitHub release page for tag v1.0.0 on ggml-org/llama.cpp is live and carries an explicit release timestamp: the page shows "github-actions released this 13 Nov 10:20", marking tag v1.0.0 at commit b1b770d, and labels it "Latest." The release notes describe removal of 35 deprecated llama.h functions, promotion of the NextN/speculative API, OCP FP8 KV caches, a host-memory MoE expert cache, and new architectures (Kimi-K3.1-Pro, Ripple-65B-Preview, xing4_0, drama-3 TTS, MageVL-Cowork).

Round 3 · Finding 2

NVIDIA / Arm "approach" — verification against 2026-11-13 primary sources

Executive Summary

The central claim could not be substantiated. I could not locate, fetch, or cite any NVIDIA or Arm statement — confirmation, denial, "no comment," or otherwise — regarding an approach or acquisition of Arm, dated 2026-11-13 or any other date. No NVIDIA newsroom or investor-relations item mentioning Arm appeared in the 2026-11-13 surface of either site. The Financial Times original was not fetched: no search I ran returned an FT URL for this story, so I have no verified FT link to fetch. Per the mission's own standard, the "NVIDIA/Arm approach" therefore stands as UNVERIFIED — aggregator/headline-only, and I am not restating it as fact.

What I did establish, from NVIDIA's own newsroom, is a different and larger story: Jensen Huang had already resigned as President, CEO and board member, and Colette Kress was serving as Interim CEO on 2026-11-13. That is the direct answer to the "who is acting CEO" sub-question — but the source is dated 2026-11-12, one day before the window, so it is dated-primary background that establishes standing status on 11/13 rather than an in-window publication.

Key Findings

#FindingConfidence
1No NVIDIA or Arm confirmation, denial or comment on an Arm approach could be located for 2026-11-13High that I found none; this is not evidence that none exists

Anthropic's IPO as of 2026-11-13: what the primary record actually shows

Executive Summary

The central finding is a negative one, and it is established from the primary record: as of 2026-11-13 20:22 UTC, the SEC's EDGAR system showed no priced offering for Anthropic, PBC — no 424B4 (final prospectus), no 424B3, and no filing of any kind dated 2026-11-13. Anthropic's most recent registration-statement filings were a second S-1/A on 2026-11-10 and a batch of five free-writing prospectuses (FWPs) accepted 2026-11-12. The company has CIK 0002130357, file number 333-299633, and a reserved ticker of ANT, but EDGAR's exchanges field is null — no exchange had been recorded.

That means every specific term in the circulating claim — price per share, implied valuation, and a 2026-11-19 listing date — cannot be sourced to a dated primary artifact and must be treated as unverified. I was unable to retrieve the Reuters or Bloomberg copy on the reported exclusion of mainland-China and Hong Kong investors from the order book; that claim is likewise unverified.

In short: the deal is demonstrably in marketing, not demonstrably priced.


Key Findings

1. Anthropic had NOT priced its IPO as of 2026-11-13 (Confidence: High)

EDGAR full-text search, restricted to root_forms of 424B4 and S-1 with file_date between 2026-11-01 and 2026-11-13, returned 16 hits — every one of them an S-1, S-1/A or S-1 exhibit. Not a single 424B-series document appeared. (efts.sec.gov full-text search, response timestamp Fri, 13 Nov 2026 20:22:05 GMT)

The issuer's own filing index confirms the same gap. (data.sec.gov/submissions/CIK0002130357.json, response timestamp Fri, 13 Nov 2026 20:22:07 GMT)

Round 3 · Finding 4

Findings: The Nonprofits' Suit Against Anthropic, Google, Meta, OpenAI and SpaceX — Caption, Court, Docket and 11/13 Procedural Status

Research window: 2026-11-13 (00:00–24:00). Report compiled 2026-11-13 ~20:22 UTC.


1. Executive Summary

The lawsuit is real at the level of press coverage; it is UNVERIFIED at the level of a court record. Multiple independent newsrooms published stories about it on 2026-11-12 evening UTC and again through 2026-11-13, and I retrieved those headlines and their exact publication timestamps from a dated news feed fetched today. But I could not retrieve a single primary legal artifact: no case caption, no court, no docket or case number, and no procedural status. Two direct attempts at primary records — the San Francisco Superior Court public case-information system and the body of the Politico article — both failed at the transport layer (timeouts), not because the records were shown to be absent.

Accordingly, per the mission's evidentiary rules, every element of the caption/court/docket question must be reported as unverified. I am not able to state that the case exists in a court, and I am equally not able to state that it does not.
