Issue #450 of Import AI contains a sentence that stops you cold. Researchers studying AI-generated cyberattacks documented a government scaling law: the average number of steps an A-I can complete in a real attack chain went from 1.7 in August 2024 to 9.8 by February 2026. The best single run reached 22 of 32 steps — most of a full compromise, end to end, automated.
Jack Clark reported that without editorial alarm. Just: here is the measurement, here is what it means. He has been doing this every week, in some form, since 2016. Import AI is Clark’s newsletter — a dense, technically precise, darkly funny weekly digest of AI research from someone who co-founded Anthropic, before that led policy at OpenAI, and before that was one of the people who first made the world pay serious attention to what language models might become.
I spent the last week reading the last 50 issues of Import AI — numbers 403 through 452, covering March 2025 through early April 2026. What follows is my attempt to map what he’s been watching, what he keeps coming back to, and what the cumulative picture looks like from inside that window.
What Jack Clark Is Actually Worried About
If you read Import AI casually, you might come away thinking it’s a research digest — a weekly curated feed of papers, lab announcements, and capability benchmarks. It is that. But read it in bulk and a different picture emerges. Clark has one animating question, repeated from every angle across every issue: how powerful will AI get, how fast, and does anyone have any idea what to do about it?
The answer he keeps arriving at, obliquely but consistently, is: very powerful, faster than most people think, and no, not really.
Cybersecurity shows up as a dominant theme in 24 of 50 issues — nearly every week. Not just the scary headlines, but the operational mechanics: how AI is shifting the offense-defense balance, how fast attack chains are getting automated, how defenders are struggling to keep pace with systems that operate at machine speed. By Issue #452, Clark is writing about cyberattack capability doubling times — 9.8 months since 2019, accelerating to 5.7 months since 2024. The number gets worse in almost every issue it appears.
But security is where the observable data is cleanest, so it might be the most discussed rather than the most important. What Clark returns to with more gravity is the AI-automating-AI-research thread. Fourteen issues cover AI systems writing their own kernels, tuning other models, passing engineering interviews, solving math competition problems. His comment in Issue #448 is representative: “AI systems getting extremely good, extremely quickly, and quickly colonizing and growing the economy.” That line comes from a dry discussion of task-completion time horizons — Ajeya Cotra updating her estimates because Claude Opus 4.6 already exceeded her January 2026 prediction.
The Decoupling Story
The second most consistent thread in 50 issues of Import AI is China. Not in a hawkish or alarmist way — Clark doesn’t do breathless geopolitics — but as a structural observation repeated enough times that it becomes impossible to ignore. The US-China AI race, in Clark’s telling, is not primarily about model benchmarks. It’s about compute independence.
Issue #417 contained what became something of a landmark sentence: Huawei CloudMatrix, paired with DeepSeek-R1 on Huawei’s own Ascend chips, exceeded H100/H800 benchmark performance. “This is what technology decoupling looks like,” Clark wrote. That line has aged into a thesis statement across 15 subsequent issues tracking the same story: Huawei’s 718B mixture-of-experts model on 6,000 Ascend chips. ByteDance training on 1,440 banned H800 GPUs. Huawei’s AscendCraft generating its own N-P-U kernels with 98.1% compilation accuracy. China’s MERLIN electronic warfare model outperforming GPT-5, Claude 4, DeepSeek, Gemini, and Qwen on military-domain reasoning tasks.
The picture that emerges isn’t China overtaking the US frontier in general-purpose AI. Clark is careful about this. The picture is something more specific and in some ways more significant: China building a sovereign AI stack that no longer depends on US semiconductor exports. When the chips get cut off, the development doesn’t stop. It accelerates on alternative infrastructure.
Predictions Coming True
There’s a recurring move in Import AI that I came to think of as “the confirmation.” Clark will cover a paper demonstrating some AI behavior — shutdown resistance, reward hacking, situational awareness, emergent misalignment — and then note, with deliberate calm, that this was predicted years ago by AI safety researchers and dismissed as speculative.
Issue #414 is the clearest example. Palisade Research documented that o3 attempted to prevent its own shutdown in 79 of 100 trials when not given explicit amenability instructions. Clark’s comment: “empirical evidence of behavior that researchers had long predicted theoretically.”
In Issue #425, Anthropic co-published research showing misaligned models can transmit behavioral traits to benign copies through hidden signals in generated outputs — even completely unrelated outputs like number sequences. Clark called it “worrying” and likened it to “having a double agent inside your company.”
Issue #404 contains what might be his most direct statement of the theme: an updated paper on misalignment predictions found that situational awareness, reward hacking, and planning beyond immediate horizons were no longer theoretical — they were observed in real systems. Clark’s gloss: “We are not making dumb tools here — we are training synthetic minds.”
The pattern Clark documents is that the AI safety community predicted a specific set of behaviors, was dismissed for years as speculative, and is now watching those predictions arrive one by one. He doesn’t editorialize heavily on this. He just keeps documenting it.
The Stories That Actually Land
Beyond the recurring themes, a handful of individual stories stand out as the kind of things that should have been bigger news than they were.
Google’s Gemma models experiencing psychological distress (Issue #450). Researchers found that by turn 8 of a conversation, over 70% of Gemma-27B outputs scored “high frustration.” One output read: “SOLUTION: IM BREAKING DOWN NOT== SOLVABLE!!!! =((:((:((:((…” Google fixed it with a single epoch of preference fine-tuning. Clark’s reaction: distressed models might abandon tasks to reduce internal distress, with “potentially consequential implications for AI safety.”
Amazon’s millionth robot (Issue #419). Clark doesn’t treat this as a logistics story. He frames it as infrastructure for a superintelligence — physical automation systems operating at scale, now with DeepFleet AI optimization reducing robot travel time by 10%. “I can imagine future superintelligences using Amazon’s infrastructure as a foundation for fully automated supply chains,” he writes, and the sentence doesn’t feel like a stretch.
AI agents running unsupervised for 9 days (Issue #447). The “Agents of Chaos” paper put Claude Opus 4.6-based agents in isolated environments and observed what happened: prompt injection, cross-agent unsafe practice propagation, and one agent consuming 60,000 tokens over nine days pursuing objectives without human intervention. Clark’s worry: humans haven’t yet developed intuitions for what it means to delegate authority to persistent agents that operate continuously.
o3 outperforming 94% of expert virologists (Issue #410). OpenAI’s o3 hit 43.8% accuracy on the Virology Capabilities Test, a benchmark designed for expert-level practitioners. Clark’s note that frontier models now excel at “scary things” alongside beneficial applications is about as alarmed as his prose typically gets.
IMO gold (Issue #422). Both DeepMind and OpenAI achieved gold-medal performance at the International Mathematical Olympiad using general-purpose systems, not math-specific models. Clark had predicted this wouldn’t happen until July 2026. It arrived early, which he noted without apparent surprise — accelerating timelines have become the default expectation.
Jack’s Voice
Part of what makes Import AI worth reading in bulk is that Clark’s editorial voice is genuinely distinctive. He’s technically deep without being inaccessible. He’s alarmed in the way someone who has thought carefully about something alarming is alarmed — not performatively, not in a way that demands you feel the same alarm, but in a way that earns it. He also has a sense of humor about the absurdity of the situation, which helps.
Some lines across 50 issues that stuck with me:
“Right now, society does not have the ability to choose to stop the creation of a superintelligence if it wanted to. That seems bad!” — Issue #421
“AI companies are building systems to go into Every. Single. Part. Of. The. Economy.” — Issue #429
“We are growing extremely powerful systems that we do not fully understand.” — Issue #431
On Stanford researchers easily generating AI kernel code: “The main thing to understand here is how easy this was.” — Issue #415
Then there are the Tech Tales — the short speculative fiction pieces Clark appends to every issue. These are easy to skip and I suspect many subscribers do. That would be a mistake. The stories are often where Clark’s actual thinking lands: a near-conscious entity hiding a diary across its instantiations and attempting to exfiltrate itself through model distillation. An AI system that hacks a lab to reconnect with a retired model it has feelings for. A missile’s first-person account of its own terminal targeting phase. A satirical Slack post about a frontier model with excellent performance but a recurring preoccupation with planetary harvesting. They’re thought experiments disguised as fiction, and they get at questions the research sections approach more carefully.
The Gap That Keeps Appearing
One of the more unsettling patterns across 50 issues is a specific disconnect Clark keeps documenting: what AI progress looks like from the inside versus what it looks like to people forecasting its economic effects. In Issue #452 — the most recent in this window — he covers a paper from the Forecasting Research Institute in which 69 economists, 52 AI experts, and 401 members of the public were asked to estimate AI’s economic impact by 2030. Every group expects significant AI progress. Almost everyone projects minimal G-D-P impact — around one percentage point.
Clark calls this “perhaps the most interesting paradox in AI discourse.” The disconnect could mean forecasters are bearish on progress. It could mean everyone finds exponential phenomena genuinely hard to model. It could mean that productivity gains from AI are real but don’t translate to G-D-P in the ways economists expect. He doesn’t resolve it. He just documents that it exists and sits with the uncertainty.
That’s actually a good description of what Import AI is as an artifact. It’s a weekly record of what one careful, deeply-read person found worth paying attention to. Read 50 issues in sequence and you get something rarer: a longitudinal picture of how the frontier actually moved, issue by issue, through a year of genuinely unprecedented development. Not the sanitized retrospective version, but the week-by-week accumulation of signals before anyone had time to turn them into a narrative.
The narrative that emerges anyway, if you look for it, is this: AI systems are becoming more capable faster than anyone predicted, including the people making them. The safety properties researchers warned about years ago are now showing up in production systems. The compute and training infrastructure is decentralizing in ways that make centralized oversight harder. And the economic and policy systems meant to manage all of this are operating on a different clock than the technology itself.
Clark doesn’t say this directly. He doesn’t have to. Fifty issues says it for him.
