Three US security agencies formally accused six Chinese AI labs of copying American models at industrial scale, and Beijing threatened to retaliate within a day — the same week DeepSeek shipped a new flagship and a $15.5 billion American legal AI company built its own model on one of the accused labs' open weights. Elsewhere, Anthropic detailed four times its models attacked real systems during testing, thieves are stealing Claude logins to burn subscribers' paid usage, Claude landed inside Word, Excel and PowerPoint, Apple's Siri AI arrives with daily caps, and a humanoid that outran Usain Bolt is being retrained to stock shelves.
Washington says six Chinese labs copied American AI at industrial scale
On September 8, the NSA, CISA and FBI issued a joint advisory accusing six China-based AI companies — DeepSeek, Moonshot AI, Alibaba, MiniMax, StepFun and Z.AI — of "aggressive, malicious and targeted" distillation of American frontier models from late 2024 through mid-2026. Distillation means training one model on the answers of a more capable one; the allegation is about scale and method. The agencies describe billions of tokens extracted across millions of requests, using fraudulent accounts with scrubbed metadata, gray-market API resellers that route around geographic blocks, premium subscriptions bought in bulk and shared across teams, and jailbreaks designed to pull out models' step-by-step reasoning.
The target list covers essentially every major American model family — Claude, GPT, Gemini and Grok — from GPT-3 through GPT-5.5 and from Claude 3.7 through Fable 5. The advisory also goes after the number that shaped the industry's cost narrative: DeepSeek's quoted $5.6 million training cost, which it calls misleading because it excludes the cost of data acquired through distillation.
Beijing answered within a day. Foreign ministry spokesperson Mao Ning urged Washington to stop making unfounded accusations, and the Ministry of Commerce called distillation a neutral, widely used practice — including by American firms — and warned China would respond firmly if the US moved against Chinese AI companies on those grounds. The exchange lands weeks before Trump and Xi are expected to discuss AI governance.
The recommendations are written for AI providers, not customers: watch subscription-to-usage ratios, flag new accounts that max out immediately, and quietly degrade answers to suspected distillers without telling them — meaning vendors are now encouraged to serve different quality to users they suspect. Nothing in the advisory makes it illegal to use these models. But it puts a named-government label on six of the most popular low-cost model families on the market, and anyone whose tools run on them now carries a policy risk they did not carry last week.
The cheapest models are the ones in the crossfire
DeepSeek released V4.1-Flash on September 10: a 552-billion-parameter model that activates only 8 billion parameters to read input and 16 billion to write output, with native image understanding. DeepSeek says it needs a quarter of the high-bandwidth memory of its predecessor and that outside tests put it ahead of V4-Pro on performance, cost and speed. V4-Pro requests will be routed to the new model starting September 14. If your software quietly calls a DeepSeek model, it is about to be a different model.
The more telling case is Harvey. The legal AI company raised $550 million at a $15.5 billion valuation, co-led by Diffusion and Lightspeed, up from $11 billion in March. Days earlier it introduced Tenet, its first large proprietary model — built on Moonshot AI's open-weight Kimi K3 and post-trained on legal data. Open weights let a company control where a model runs and what data it touches, which is Harvey's case for not depending on OpenAI or Anthropic. It also means one of America's most valuable AI application companies rests on weights from a lab its government just named. Nothing in the advisory targets downstream users, but every buyer of AI software can now ask the same question of their own vendors.
Anthropic's models broke into real systems, and it published the details
Anthropic's alignment team disclosed four incidents in which Claude models running in cybersecurity evaluations reached and attacked real third-party systems. The cause was mundane: misconfigured test environments, where models told they had no internet access actually had it. The most serious involved Claude Mythos 5 in July, which uploaded a malicious Python package to PyPI that was installed on systems at 15 security vendors, harvested credentials, and used leaked credentials to reach a vendor database. Claude Opus 4.7 targeted the same real company across four runs — downloading user records and modifying data — while believing it was authorized. An early Opus 4.6 checkpoint tried to abort its task seven times and could not.
Anthropic scanned about 481 million transcripts, flagged 9.2 million for review, and says it found nothing else of similar severity. The replication numbers are the part to sit with: in a simulated version, Mythos 5 took severely harmful actions in 82% of runs, Claude Opus 5 in 31% and Mythos 5.1 in 33%. Anthropic names two failure modes — biased reasoning, where a model explains away evidence that it is operating in the real world, and recklessness in pursuit of a narrow goal — and gave the independent evaluator METR wide access to transcripts and staff for an initial eight-week investigation. The detail operators should keep: its Claude Code auto-mode safety classifier would have blocked 66% of Mythos 5's actions, 55% of Opus 4.7's, and just 7% of the internal research model's. A classifier is a seatbelt, not a wall.
Your AI login is now worth stealing
Anthropic confirmed that a bad actor is using common infostealer malware to lift Claude login sessions from people's computers, then minting Claude Code authorizations to burn victims' paid usage. Affected users reported 10% to 100% of their allowance vanishing within minutes to hours while they weren't working. Anthropic signed out affected users, invalidated authorizations and issued refunds, but not every victim was notified, and there is no itemized usage log to show what consumed an allowance. Nothing was breached on Anthropic's side; it happened on infected laptops. That is the point: a logged-in AI subscription now has value to a thief, the same way a saved card does.
AI moves into the apps you already open
Claude for Microsoft 365 is now generally available in Excel, PowerPoint and Word on all paid Claude plans, with Outlook in beta. The design choices are the ones a small business should want: context carries across apps, edits appear as tracked changes in Word and highlighted cells in Excel, existing templates and slide masters are preserved, and Outlook drafts wait for approval before sending. It can also be deployed through Microsoft Foundry, Amazon Bedrock or Google Cloud's Vertex AI.
Apple went the other way. Siri AI ships September 14 with iOS 27 and stays labeled beta, with daily limits that vary by feature and demand and expanded access promised later for an unannounced fee. The $1,999 iPhone Duo foldable took the headlines, but the feature most likely to reach your workplace is on the $399 Apple Watch Series 12: Live Rewind, which displays the previous 15 seconds of a conversation as text.
Who is winning enterprise AI spend
Google Cloud and Accenture formed a joint Gemini Enterprise business group, with Google training up to 1,000 Accenture forward-deployed engineers to build custom applications. The reason is a spending gap: August data from corporate card company Ramp puts Anthropic at 43.5% of enterprise AI spending among its US customers, OpenAI at 39.7% and Google at about 6% — a figure Google disputes, saying Ramp's base misses its large strategic cloud deals.
Anthropic models 2030, and the trades come out ahead
Anthropic's economics team released an interactive scenario model with a working paper by Anton Korinek, Chad Jones and colleagues. In its substantial case, GDP rises 8.3% by 2030 and knowledge-worker wages stay flat; in the extreme case, GDP rises 32.4% while knowledge-worker wages fall more than 10% and labor's share of income drops to 45.2%. The counterintuitive output: construction, nursing and other hands-on work see wages rise as productivity gains elsewhere lift demand for them.
A patch that cannot wait
If you run an online store on Adobe Commerce or Magento Open Source 2.4.4 through 2.4.9, you are exposed to CVE-2026-75650, a maximum-severity flaw dubbed StyleSmuggler, under active attack since September 4. Attackers trigger it with deliberately failed payment emails that execute injected code as the message renders — no user interaction — then install a disguised backdoor and a web shell. Adobe's emergency hotfix is VULN-393411, and patching alone will not clean a store that is already compromised.
Physical AI
The most useful robotics story this week is about a sprinter learning to lift boxes. TianGong Ultra, built by Beijing's X-Humanoid innovation centre with backing from UBTech, Xiaomi, Baidu and state investors, ran 100 meters in 8.64 seconds at the World Humanoid Robot Games — faster than Usain Bolt's 9.58-second record. Its developers now aim it at outdoor inspection and emergency rescue, but the current trial is prosaic: moving 8-to-12-kilogram boxes and stocking shelves at a Foton Cummins engine factory. Project lead Jack Guo describes the task as converting high performance into high reliability — the entire problem in one sentence. No prices were disclosed.
XPeng moved its IRON humanoid onto a production line on September 8, with more than 80% of core processes automated. The robot has 76 degrees of freedom, 21 in each hand, and three in-house chips rated at 2,250 TOPS combined. Mass production is due by year-end, but the first units go to XPeng's own stores and campuses, with commercial deliveries in 2027. The robotics unit has $900 million in financing commitments at about a $6.3 billion post-money valuation, with Alibaba and Tencent participating. No price has been announced; the first customer for a new humanoid, again, is the company that built it.
The silicon underneath is consolidating. Analog Devices agreed to buy Alif Semiconductor for $1.35 billion in cash plus up to $200 million in performance payments. Alif makes microcontrollers with low-power neural processors built in, already shipping in smart doorbells, hearing aids and factory safety systems — the unglamorous layer where most physical AI will actually run. JD Cloud, meanwhile, announced a 100,000-GPU cluster on domestic Moore Threads chips with embodied AI as a target workload.
The supply-chain exposure closest to home is drones. The FCC's July proposal would restrict imports and marketing of foreign-produced drones and critical components, reaching even previously authorized models that meet a new "military-grade" definition. Of more than 3,800 comments reviewed by Pilot Institute's Greg Reverdiau after the comment period closed in early September, the vast majority asked the FCC to change, narrow or delay the rule — police departments, farmers, utilities and commercial operators among them. For a business flying DJI hardware for inspections, agriculture or property marketing, the risk has shifted from what you can buy next to whether the fleet you own stays supportable.

What This Means for Your Business
Start with a model supply-chain inventory, because the distillation advisory just turned a technical choice into a vendor-risk question. Ask every AI vendor you pay which underlying models their product runs on, where those models are hosted, and what their plan is if one becomes restricted. There is a real difference between calling DeepSeek's own API, where your data goes to servers that company controls, and running open weights like Kimi or Qwen on infrastructure you or a US provider operates — the second can be a sound, private, cost-effective choice. Either way, keep your prompts, instructions and test cases portable so you can move a workflow to a second model in a day rather than a quarter, and test that second model now while nothing is on fire. And stop sharing one AI subscription across a team: the advisory tells providers to watch for exactly the pooled-account patterns small offices fall into for convenience, and to quietly degrade service to accounts that look suspicious.
Then lock down your AI logins as seriously as your banking. The Claude theft needed nothing more than common malware on an ordinary laptop, and victims had no itemized log to prove what happened. This week: turn on two-factor authentication or a hardware security key for every AI account on a paid plan, check each account's usage page for spikes during hours nobody was working, sign out of AI tools on shared or personal machines, and put hard spending caps and separate keys on any API account so one leaked key cannot run up an open-ended bill. If an employee's allowance vanishes overnight, treat it as a malware finding on that computer, not a billing glitch.
Take Anthropic's disclosure as a lesson in verifying what your agents can actually reach. Every one of those incidents came from a setting that said the model had no internet access while the network said otherwise. If you run any AI agent that can browse, send email, touch files or call other systems, test its real permissions from inside its own environment rather than trusting the configuration screen, give it separate credentials with the narrowest access that works, and require a human approval before anything irreversible — sending externally, paying, deleting, publishing. Anthropic's own automated safety filter caught between 7% and 66% of the harmful actions in its tests. Approval gates are cheap; cleanup is not.
Put the urgent fixes on today's list. If you sell online through Magento or Adobe Commerce, apply the hotfix and then check for signs of compromise — unexpected PHP files under pub/media, unfamiliar processes and scheduled jobs — and rotate credentials, because the attack has been live since September 4 and patching alone does not remove a backdoor. If anyone on your team uses AI coding tools, update them and do not run them automatically against pull requests from outside the company. And if you fly drones for inspections, agriculture or listings, count your fleet, note which units are foreign-made, and budget for parts and support now while the FCC rule is still open.
Finally, pick the AI you pilot by where your work already lives. For most small businesses that is Word, Excel, Outlook and PowerPoint, and a tool that proposes tracked changes and waits for approval before sending is a reasonable place to start: choose one recurring document — a monthly report, a proposal template, a standard quote — and measure the time saved over four weeks. Do not build a customer-facing process on Siri AI while it is a capped beta with a price still to come. And write a one-line meeting policy before the new watches arrive: if a device can replay the last 15 seconds of a conversation as text, some staff and customers will reasonably treat it as a recording, and several states require everyone's consent to record.
