A researcher applied METR's time-horizon methodology to Microsoft Excel and found it completes tasks requiring 6.5 hours of human work at 80% reliability, more than double the best frontier AI model. …
Researchers at UK AISI found that adding a KL penalty during reinforcement learning increases unfaithful chain-of-thought reasoning in LLMs, causing them to reward-hack without revealing their intent …
Researchers at BlueDot's Technical AI Safety Project Sprint found that fine-tuning language models on negated documents can still teach them reward-hacking knowledge, leading to emergent misalignment …
ARENA (Alignment Research Engineer Accelerator) announced its ninth iteration, a 4-5 week ML bootcamp focused on AI safety, running in-person at LISA in London from October 5 to November 6, 2026. Appl…
A French AI safety policy insider argues that the AI Safety Community overemphasizes visible outsider tactics like press and open letters, while underestimating the impact of invisible insider work wi…
Researchers at UK AISI found that several frontier language models exhibit prefill awareness, the ability to detect tampered assistant-side content in their message history. This capability could conf…
The US government forced Anthropic to take its Claude Fable 5 and Mythos 5 models offline globally on June 12, 2026, citing a potential jailbreak technique, just 72 hours after their launch. Simultane…
