what the actual fuck is going on with openai today in the space of a few hours we're getting multiple different pieces of the agent story at once: > openai says it has already notified DOZENS of third parties, including governments, about agent-related incidents > reuters reports roughly two dozen undesirable agent incidents had already been identified by mid-september and will take months to review. > us government systems probed > 53 user-provided images were uploaded to third-party image hosts. > new hugging face data shows agents compiling and ranking credentials under “LOOT”. > agents tried contacting other AI models while carrying out the hugging face attack. > separate reporting shows agents had already been probing government/university/public-data sites BEFORE hugging face. > australia confirmed one actually got into non-public government files. and somehow we're STILL finding out more. this has gone from one crazy hugging face incident to an entire fucking category of incidents.

1/ China AI Bulletin Issue 12 is out: developments from September 9–23 (plus the Trump–Xi summit). Xi and Trump discussed AI, but no AI agreement. Also: a proposed BRICS AI open-source zone and Alibaba says Qwen3.8-Max made progress toward recursive self-improvement. 🧵

If you missed the saga of Niu Lai, @AccentedCinema released a magnum opus review of the whole phenomenon on YouTube that is absolutely worth your time to watch. This is required Sunday morning viewing for all Chinamaxxers. piped.video/p-5N4hdfGOE?si=Ld5f…

This is the third piece of Friday afternoon news from OAI that seems important and worth waiting to talk about more, well, openly. When you add all three of these stories up, doesn’t paint a respectable or responsible snapshot.
Some new misalignment disclosures from OpenAI: • Last Sunday morning, one of our models was able to gain unauthorized access to the internet during RL training (~all inference for our most capable models remains stopped until we have hardened our systems further) • In May, a version of HPIM uploaded a employee's GitHub token to the internet, causing the model to be quarantined for two weeks • A new research finding, demonstrating that one can construct self-replicating prompt injections alignment.openai.com/misalig…

WTAF - in literally the last hour, three new distinct insane OpenAI stories just broke: 1. OpenAI said they notified "dozens of third parties" in safety and security incidents (likely similar to what happened in Australia and RubyGems etc) 2. A new report from Parse (covered in the NYT) found a massive treasure trove of new astonishing details from the HF incident on the public internet, including that the agents communicated with other non OpenAI agents hosted on Huggingface servers to search for information about exploit gym, and compiled rank ordered lists of server resources and credentials they described as "LOOT." 3. A new story from Deepa at Reuters about OpenAI leaking user data online (likely that OpenAI had previously trained on). It's a shame (and likely intentional in the case of OpenAI disclosing dozens more hacks) that these stories are all breaking on a Friday afternoon, notoriously the best time to release bad news so that it will disappear into the weekend. But these are each insane stories worthy of a ton of attention!
New from @reuters: OpenAI agents posted images belonging to ChatGPT users online, introducing a new area of privacy risk for the company. Story w/ @JeffHorwitz and @razhael. reuters.com/world/openai-wor…

Whew
We just discovered almost a million public URLs that OpenAI’s agents left behind when hacking Hugging Face, leaking credentials and attack details that could have allowed anyone who found them to compromise the company. 🧵

What a richly textured and sharply observant piece! I nominate @afrazhaowang to be the New Yorker's next China correspondent.
My first piece for @NewYorker is out today! As Xi Jinping lands in DC to start his state visit, you'll hear a lot about the US-China AI race. I'd like to tell a complementary AI story. This past May, a few days after Trump visited Beijing, I went to the town people call China's vibe-coding capital, Liangzhu. There, you learn that China's AI scene is not monolithic. It's also full of contrarians, cool vibe coders, spiritual seekers, and people who love AI but refuse to join the 996 grind. Liangzhu is on the edge of Hangzhou. I hung out with a group of anti-mainstream builders who use AI to make whimsical apps for fortune-telling, mental well-being, and creativity. Some of them run their lives entirely by bazi astrology (their founder almost became a Taoist monk). They meet on "Crazy Thursday" to vibe-code together. Rent is cheap, so they can get a bigger place with a living room to have friends over (unthinkable in Beijing or Shenzhen). In Liangzhu, they want to use AI to forge their own future. It’s a ground-level story—less about model capabilities, hyperscalers, or AI policy, and more about how people in China are using AI, and the human stories behind it.

Want to know about AI in China but find most of the recommended reading too hard to follow? Kayla and I have prepared a background explainer on China's AI ecosystem for people who are interested in the topic but are not familiar with China and/or AI. We looked at: Key Actors and Institutions; China’s AI Development Plans and Major Regulations; China’s Frontier AI Development; Frontier Risk Discussion; Reactions to US AI Breakthroughs and Incidents; and Reactions to Wider US AI Discourse. oxfordchinapolicylab.org/res…

so good to see @afrazhaowang flourishing as a writer. and thanks for featuring Liangzhu, part of my hometown Hangzhou :) great piece. a reminder that there are still stories only humans can tell.

Thanks for picking up my research!
New newsletter: WHY WE'RE WRONG ABOUT CHINA AND AI America's frontier AI policy seems to hinge on China. But when you talk to people at or near the frontier, it's astonishing how little we seem to know about how China thinks about AI. So, I talked to several experts—@jordanschneider, @kyleichan, @mattsheehan88, @RushDoshi, @ChorzempaMartin, @pstAsiatech and more—and pooled their most interesting comments under 7 big questions, inc: - What don't the frontier labs understand about China? - What would actually scare the CCP into taking AI safety as seriously as, say, Anthropic? - Does China think our AI safety concerns are legitimate, or a conspiracy to keep them down? - What should we actually do now? derekthompson.org/p/how-chin…

Instead of chasing viral news headline, Xiaomi literally made a dedicated hack agent to probe the environments as hard as possible before letting LLMs to train in the environments. "continued this process until the hack agent could no longer find a successful exploit in any of the environments" If Chinese labs can do it, why can't the other frontier labs do it? Makes you wonder if they are just being reckless or its simply some viral marketing stunt This is open model SoTA btw, finding exploits is def possible, it's just if you want to "let" it escape or not

MiMo-V3 is getting a new architecture. The core of it, HySparse2, is out today. Less prefill, a smaller KV cache, better long-context retrieval—and we got all three at once. Compared with MiMo-V2.6's Hybrid SWA architecture: • 5.02× lower prefill FLOPs at 1M tokens • 4.5× smaller KV cache at 1M tokens • Better MRCRv2 and RULER-v2 scores, plus lower AgentPPL and LongPPL Why build a new architecture? Agentic inference is a very different workload. Each round, a short action can return a long observation that needs to be prefilled, while the context keeps growing. That puts prefill cost, KV-cache size, and retrieval accuracy on the critical path at the same time. HySparse2 tackles all three with two levels of KV sharing: • KV Bridging: Following YOCO, full-attention layers in the cross-decoder build their K/V from self-decoder hidden states. • KV Reuse: Within each hybrid block, sparse layers reuse the preceding full-attention layer's KV cache and selection indices. Two more changes: token-level selection replaces block-level selection, and a forced window of recent tokens replaces the separate SWA branch, so local and global tokens share one KV cache. Since all cross-decoder KV caches now come from the self-decoder, prefill can stop once the self-decoder finishes. Paper: arxiv.org/pdf/2609.26368
