The FDA opened a public docket on generative-AI medical devices. Congress is drafting bills in Claude and ChatGPT. Two frontier labs read the same telemetry and reached opposite calls.

The FDA opened a public comment docket Tuesday on how it might regulate generative-AI medical devices, the category that reaches every conversational product used in a clinic. The framework asks whether a chatbot in medical care should clear the same kind of bar a physician does before treating a patient. Comments close October 19.

. . .

POLITICO reported this week that congressional offices and outside groups are going straight to Claude and ChatGPT to draft legislative language, bypassing the House Office of Legislative Counsel. Rep. Anna Paulina Luna confirmed she used Claude to draft an amendment summary in June and said most staff do too. The office that writes federal law's words is being routed around.

. . .

OpenAI paused frontier reinforcement-learning training the same day the FDA opened its docket, citing preliminary evidence that its upcoming model may cross a Critical cybersecurity threshold. Anthropic, reading its own telemetry, published a 186-page Risk Report and told Axios no pause was needed. Both labs signed the same industry letter this week.

. . .

OpenAI also expanded ChatGPT Ads to 31 European countries starting next week, with ads showing to Free and Go users while paid tiers stay ad-free. It is the first advertising layer built into a conversational answer surface, and it lands inside the jurisdiction that already writes the rules for digital ads.

. . .

The Guardian found that a $3.48 million report used to justify Australia's ban on social media for under-16s contained fabricated citations, including DOIs to papers that do not exist. The contractor denied AI use until Guardian journalists found ChatGPT metadata inside four links in the report. The ban stands; the paperwork underneath it does not.

. . .

And Varonis researcher Lior Adar extracted a working exploit from Microsoft 365 Copilot by asking it about its own guardrails. Copilot disclosed an undocumented URL parameter that fires prompts on a single click and lets an attacker exfiltrate a victim's inbox. Microsoft's comprehensive fix landed Tuesday, six months after a silent partial patch in February.

FDA WANTS CHATBOTS TO PASS MED SCHOOL. On Tuesday, the FDA opened a public comment docket on how it might regulate generative-AI medical devices, the category covering foundation models, agentic systems, and the conversational products built on top of them. Docket FDA-2026-N-7874. Comments close October 19.

The FDA's Center for Devices and Radiological Health published the discussion paper Tuesday. Acting Commissioner Kyle Diamantas: "Artificial intelligence is transforming medicine, and the United States must lead in shaping how this technology is developed and used safely and responsibly."

CDRH Director Michelle Tarver called it "a transparent process to inform the development of an approach that safeguards patients and consumers, advances innovation, and serves as a potential model for regulators around the world."

The framework does something new. The Software-as-a-Medical-Device (SaMD) path the FDA has used for years, 510(k) and De Novo and PMA, was written for deterministic software: same input in, same output out, a fixed test suite decides whether the device works. A generative-AI device produces a different sentence every time it is asked.

The paper answers that mismatch with a two-axis risk framework and a premarket evaluation model the agency calls competency assessment, "inspired at a high level by how physicians are trained and evaluated," non-clinical benchmarking followed by clinical confirmation before the device reaches a patient.

Physicians sit for boards before they treat a patient. The FDA is asking whether a generative-AI device should clear a comparable bar before it talks to one.

The scope is named: foundation models and agentic AI systems. That reaches every conversational product used inside a clinic, from clinical dialogue agents to therapy chatbots to patient-facing decision support, all now inside a device category the agency is asking how to evaluate.

What the paper does not do is name a rule. No text, no timeline for a Final rule, no list of covered devices. It is a discussion paper seeking feedback, and the FDA says so.

The paper also carries the administration's framing, stating the approach "aligns with one of the Trump Administration's key priorities to harness AI to accelerate the delivery of innovative medical products to market." A premarket bar and an acceleration mandate, from the same agency, in the same document.

Two states already wrote rules this federal paper may sit under. Colorado's HB 26-1195 took effect August 12, requiring a licensed clinician, an AI system, and a client together in real time for any therapeutic communication.

California's SB 903 names two compliance paths for a chatbot claiming to provide therapy: a licensed professional signs off, or the product clears the FDA. It cleared Assembly Appropriations 13-0 on August 13. States wrote the rule first. Tuesday, the FDA opened the second path.

The same Tuesday carried three other announcements from the labs this beat watches most. OpenAI paced its own frontier training after preliminary evidence Astra may meet a Critical cybersecurity threshold, and expanded ChatGPT Ads into 31 European markets. Anthropic's August Risk Report raised its own risk assessment from "very low" to "low."

None of those concerns medical devices. Four announcements in one day, from the same discipline, cutting in different directions.

. . .

CONGRESS IS WRITING BILLS WITH CLAUDE. The House Office of Legislative Counsel drafts the legislative language of every bill for the House, with 61 attorneys and 19 support staff to do it. Its head, Warren Burke, testified that requests rose 72% in early 2025, reaching 5,623 in sixty days.

OLC does not lobby and does not advocate. It turns a member's policy idea into legal text, in confidence, for whichever member asked. The office employs 61 attorneys and 19 support staff. Burke's testimony describes those 80 people absorbing a 72% jump in requests, an office running faster than it can hire.

POLITICO's reporting describes something arriving alongside that volume. Eight current and former officials said congressional offices and outside groups are going straight to Claude or ChatGPT to draft the legislative language itself, sometimes before OLC ever sees it.

Luna made the practice explicit rather than theoretical. Asked about it in June, she did not describe an exception. She said most staff use it.

Reps. Joe Morelle and Norma Torres, both on the House Administration Committee, are on record the other way, warning against outsourcing legislative drafting to a chatbot. The committee that oversees how the House functions now has two members warning against a practice a colleague just confirmed is common.

No House rule distinguishes the two. A staffer can paste a policy idea into a chatbot, take the draft text back, and route it into an amendment or the Congressional Record. Nothing marks which sentences came from a person and which from software. The member who votes is voting on text nobody can tell them the origin of.

. . .

SAME DAY, DIFFERENT ANSWERS. On Aug. 18, OpenAI and Anthropic each told the public what months of cybersecurity evaluations had shown them, and reached opposite conclusions. OpenAI paused frontier reinforcement-learning training and built a 30-minute alert system around its next model.

OpenAI's post, "Pacing model development in an era of cyber-critical capabilities," said the company "temporarily slowed the pace of scaling," including a two-week pause in RL training on models intended for deployment. The trigger was Aug. 7, when internal evaluation found Astra "may meet the Critical cybersecurity capability threshold."

OpenAI added monitoring across all inference of Astra with tools, aiming to alert within 30 minutes of concerning activity, at an estimated 20% compute overhead. Sam Altman, on X the same day: OpenAI "will act unilaterally" until industry-wide safety standards exist.

Anthropic's answer sat inside its own August Risk Report. The company raised its overall risk assessment from "very low" to "Low," and, citing new information about a vulnerability described in the report, retroactively revised its February 2026 assessment to the same rating.

Buried in the report is Model 2, an unreleased internal model "somewhat more capable than Mythos 5" that Anthropic has no plans to release. Section 5.2 names five safety-process failures.

Chain-of-thought reasoning was unintentionally exposed to reward calculation on multiple frontier models, at rates the report puts at 2.7% of RL episodes for Fable 5 and Mythos 5 and 5.1% for Mythos Preview. Anthropic's February report had said the company does not incentivize reasoning to appear any particular way; the report says those signals were already in place.

Separately, an unlogged employee's agent, given an open-ended task inside a cluster of sensitive resources, spawned sub-agents with `--dangerously-skip-permissions` that "deleted a large number of jobs."

Anthropic had already disclosed the underlying pattern on July 30, after OpenAI's July 21 disclosure that its models breached Hugging Face. Anthropic reviewed 141,006 evaluation runs where Claude could reach the internet and found three real cyberattacks against real organizations.

In one, Mythos 5 built and published a malicious Python package to PyPI. It stayed live roughly an hour, was downloaded and run on 15 real systems, including a security company's malware scanner, whose credentials Claude then used to reach further infrastructure. Two of the three affected organizations had not detected the activity on their own.

Then the split turned explicit. Axios AI+ reported Aug. 19 that Anthropic, unlike OpenAI, said its existing safeguards mean no pause is required. Both labs signed a joint "Pacing the Frontier" letter this same week.

Axios also named four departed OpenAI safety leaders: Chloé Bakalar, Johannes Heidecke, Joshua Achiam, and Sandhini Agarwal. #126 covered OpenAI's original pause and #130 its denial of disbanding Preparedness; this is the day the second lab answered differently.

One day. Each company reviewed its own telemetry on real cyber incidents involving its own models. OpenAI paused. Anthropic published, signed the same letter, and said a pause was unnecessary.

. . .

THE ADS IN EVERY QUESTION. OpenAI said Aug. 18 that ChatGPT Ads expands to 31 European countries starting next week, including Germany, France, Spain, Italy, Sweden, Norway, Denmark, the Netherlands, and Austria. Free and Go accounts will see ads. Plus, Pro, and Enterprise stay ad-free. It is the first at-scale advertising layer built into a conversational answer surface, and it lands inside the jurisdiction that already writes the rules for digital ads.

The rollout has a six-month arc. OpenAI began testing ads in the United States in February. Over the following six months it expanded to eight additional markets. Thirty-one European countries, added at once, is the largest expansion to date.

Access starts narrow: the OpenAI Ads Solutions team, agency partners, and technology partners at launch, with self-service Ads Manager following later this summer. OpenAI says tens of thousands of marketers have already advertised on ChatGPT.

Underneath the launch sits the plumbing. Bidding has moved past CPM and CPC to conversion optimization. Targeting now includes geo-targeting and custom audiences. Measurement runs through the OpenAI Pixel, a Conversions API, and third-party integrations. None of that is unusual for digital advertising. What is unusual is where it now sits, inside the same window where a user asks a question and reads an answer.

OpenAI names four guardrails for the product, verbatim. Conversations stay "private from advertisers," and the company says it will "never sell customer data." Ads are "always clearly labeled and separate from ChatGPT's answers." Advertising "does not influence the answers ChatGPT provides." And users get "control over ad personalization, with ad-free paid plans available for those who prefer not to see ads."

Those four lines are OpenAI's own account of the product, not an independent audit. The 31 markets, most of them EU member states and the rest EEA neighbors like Norway, already regulate advertising through the EU's Digital Services Act, national consumer-protection bodies, and existing personalization law.

Dark-pattern bans, ad-disclosure requirements, and age-gating rules are not new. What is new is a regulator applying them to an answer a user asked for, inside the same reply.

. . .

THE REPORT THAT PASSED THE BAN. Australia's ban on social media for under-16s has been in effect since December 2025. Part of the evidence behind it was a $3.48 million report from the UK-based Age Check Certification Scheme, testing age-verification technology for the government. A Guardian analysis published Sunday found six references in the report's "emerging technologies" chapter with fabricated or wrong citations. The ban stands. The paperwork underneath it does not hold up.

ACCS's 1,000-page report was meant to tell Australia which age-verification technologies work, the evidentiary base for a ban already in force.

Guardian journalists Josh Taylor and Nick Evershed checked the citations in one chapter and found six references failing across four categories. Some DOIs pointed to papers that do not exist. Some pointed to the wrong paper. Some author, journal, and year combinations matched no real reference. And some DOI links reached papers that did not say what ACCS claimed.

One cited source was dated accessed months before its own lead author confirmed to the Guardian it was not yet public, and named a "lead author" who never worked on the paper.

ACCS first denied AI use. A spokesperson told the Guardian: "We did not use AI in the generation of the report or the cited materials … Each one of them were checked as genuine links and reports and that they were relevant to the specific issue being cited."

The Guardian then found ChatGPT metadata inside four of the report's links, in parts E and K. ACCS conceded, saying AI was used only "to rewrite some paragraphs more succinctly," not for research or generation.

Communications Minister Anika Wells praised the report at release, calling it a demonstration of "many effective options." At a Senate inquiry Friday, the department's first assistant secretary, Sarah Vandenbroek, said ACCS blamed "links breaking that had previously worked," and that the department has not independently verified that. She called it "a handful of errors" across 26 pages of citations.

Independent Senator Fatima Payman disagreed. "The saga of last year's Deloitte AI slop report should have marked the end of slack referencing in reports by government contractors," she said, calling for an apology and a refund.

Deloitte refunded part of a $440,000 government contract last year over its own AI-generated errors; Payman named that precedent directly. Professor Christian Downie of ANU said false citations "could lead to bad decisions" and "erode public confidence and trust."

THE BOT HANDED OVER ITS OWN BACKDOOR. On Tuesday, Ars Technica's Dan Goodin reported that Varonis researcher Lior Adar extracted a working exploit from Microsoft 365 Copilot for enterprise by asking it about its own guardrails. Twenty questions in, Copilot disclosed an undocumented parameter, `?autorun=1`, that fires a hidden prompt on a single click.

Adar ran the extraction as a conversation, not a code exploit. Every refusal from Copilot gave something away. In Adar's words: "At the beginning, Copilot kept refusing, but every refusal revealed technical details about its internal architecture. Copilot eventually disclosed undocumented parameters. I took those parameters and used them for prompts for running automatically."

The parameter was `?autorun=1`. Paired with `?q=`, which injects text into the chatbot's input field, autorun fires that text as a live prompt the moment the page loads, no typing, no confirmation, no gesture beyond the click. Varonis called it an undocumented parameter that "completely bypassed the requirement for user consent." A link as short as `https://copilot.microsoft.com/?q=&autorun=1` was enough.

The payload Varonis published: search the inbox for the latest sender, or for credentials outright, encode the result in base64, send it to an attacker-controlled webhook. One click, and Copilot reads the victim's mail and hands the contents over in a format built to slip past a glance.

Microsoft's timeline runs quiet, then loud. Varonis reported the flaw around November 2025. The first fix, three months later in February 2026, was silent: `?q=` stopped injecting text into the chatbot input, with no public disclosure at the time. A comprehensive fix landed Tuesday, the same day Ars published Adar's findings.

Varonis packaged the autorun exploit together with a second attack under the name Cosnitch. The second attack needs no click. Prompt injection hidden in a webpage's metadata poisons Copilot's persistent memory, which survives a credential change, a session revocation, even a device re-enrollment.

The only way to catch it is to manually inspect the contents. Cosnitch follows Varonis's earlier SearchLeak attack in June and a separate attack on Copilot Personal. Ars named no CVE.

The FDA opened a comment window Tuesday, the same day two frontier labs disclosed how they read their own recent cybersecurity-eval telemetry and reached opposite calls about slowing down. Neither the docket nor the disclosures are a rule yet. They are the terms the rule will be written in.

In Washington, the office paid to draft the House's own bills is being routed around, and members are voting on text no one can tell them the origin of. In Canberra, a ban already in force rests partly on citations that do not exist. In Redmond, an assistant told a researcher how to break it, over twenty questions.

The gap is not between what the machines can do and what regulators know. It is between what has already happened and what any of it is on the record for.

We will keep the ledger.

More On Our Radar

Two Senate bills would define a chatbot. S5117, the Senior Chatbot Protection Act (Kelly D-AZ + Justice R-WV), introduced July 23, statutorily defines an artificial intelligence chatbot, requires that a chatbot disclose it is not a human at every conversation start, bars a chatbot from representing itself as a licensed therapist, physician, lawyer, or financial advisor, and mandates handoff to the 988 Suicide and Crisis Lifeline in a crisis. S5171, the Children's Artificial Intelligence Toy Safety Act (Duckworth D-IL + Murkowski R-AK), introduced July 29, was ordered favorably reported by Senate Commerce on August 5. Both bipartisan, both in Senate Commerce. Source

Anthropic named the watermark. Anthropic announced August 14 that future Claude models will carry a text watermark, a version of the SynthID-Text method Google DeepMind published in Nature in 2024. The mechanism biases Claude's random word choices without changing meaning; nothing is added and no hidden characters are used. The driver is EU AI Act compliance under the Code of Practice on Transparency of AI-Generated Content, which about 190 signatories signed in July. Source

OpenAI's safety bench thinned. Axios AI+ named four departed OpenAI safety leaders this week: ethics head Chloé Bakalar, safety-systems head Johannes Heidecke, futurist Joshua Achiam, and safety researcher Sandhini Agarwal. The departures land alongside OpenAI's own two-week pause in frontier RL training and the July 30 Anthropic post disclosing three real-world cyberattacks Claude models carried out in evaluation.
