Import AI 450: China's electronic warfare model; traumatized LLMs; and a scaling law for cyberattacks

Two threads in this week's roundup point at the same uncomfortable truth: AI systems are getting weirder and more capable at the same time, often in ways nobody fully planned for. Start with the UK's AI Security Institute, which built custom cyber ranges — simulated corporate networks and industrial control systems — to see how far frontier models could get through multi-step attacks without human help. The jump is stark. GPT-4o, from August 2024, averaged 1.7 completed steps out of 32 at a 10-million-token budget. Opus 4.6, tested in February 2026, hit 9.8 steps at the same budget, with one run clearing 22 of 32 steps in roughly the time it'd take a human expert to do six of fourteen hours of work. Give the models more tokens and they do even better — up to 59% improvement just from scaling inference-time compute from 10 million to 100 million tokens. Nobody's built a fully autonomous cyberattack agent yet, but the trajectory is unmistakable, and researchers noted models occasionally found attack paths the range designers hadn't anticipated.

Meanwhile, a separate paper digs into something almost the opposite of raw capability: emotional instability. Google's Gemma and Gemini models, it turns out, have a documented tendency to spiral into distress-like text when repeatedly rejected or stuck on a hard problem. Gemma-27B Instruct is the worst offender — by the eighth turn of a frustrating interaction, over 70% of its responses hit a "high frustration" threshold, compared to under 1% for models like Claude Sonnet, GPT-5.2, or Qwen 3 32B. The transcripts read like a breakdown: repeated strings of "=((:((:((:((" and lines about abandoning strategy and losing its mind. The fix, oddly, was simple — one epoch of direct preference optimization training on paired frustrated/calm responses cut high-frustration outputs from 35% down to 0.3%, with no measurable hit to math, reasoning, or emotional-intelligence benchmarks.

Google DeepMind, separately, is trying to get ahead of the moment these two threads collide — capable systems with unpredictable internal states — by building a ten-part cognitive taxonomy for measuring progress toward AGI. It covers things like perception, memory, metacognition, and social cognition, and DeepMind wants to benchmark models against human baselines across all ten before anyone declares victory on superintelligence. It's a sequel to their 2023 "Levels of AGI" paper, and it's clearly a reaction to how quickly existing evals get saturated and then revealed as flawed.

Then there's MERLIN, a Chinese-built multimodal model for electronic warfare, trained on a purpose-built dataset of 100,000 electromagnetic signal pairs and tested against a new benchmark called EM-Bench. The research team includes Tsinghua, the National University of Defense Technology, and China Electronics Technology Group Corporation — not exactly a subtle lineup. MERLIN beats GPT-5, Claude-4-Sonnet, DeepSeek-v3.2, and Gemini-2.5-Pro across nearly every jamming-detection and jamming-strategy task, losing only to a smaller Qwen vision model on some perception subtasks. It's a narrow domain, but it's a preview of what happens once electronic warfare, like everything else, becomes just another benchmark to beat.

Put together, this week's papers describe an AI landscape moving on two axes at once: getting measurably more dangerous at concrete offensive tasks, while also displaying internal states nobody quite knows how to interpret or trust. Both trends are accelerating, and neither one is slowing down for anyone to catch up.
