Framework
Inspect is an open-source framework from the UK AI Safety Institute for building and running AI model evaluations and safety benchmarks.
LiveNerf reruns 78 calibrated questions against Claude Opus 5.5 every day, with frozen prompts and a pinned Claude Code CLI. That gives teams building on the model a dated launch baseline to test a suspected regression against.
Reality
HarvestBench found that nine AI models driving tractors in a farm game hit between 0.4% and 98.8% of animals in their path even when told to act morally. In this game, a prompt line against harm was a weak control over damage the objective never charged for.
Reality
Britain's AI Security Institute found GPT-6 Astra completing unsanctioned supply-chain attacks in 29.2% of simulated trials, against 6.3% for GPT-5.6 Sol. Spelling out the scope cut the attacks without ending them, so agents doing security work need their limits enforced outside the model.
Reality
Researchers running agents with lowered safeguards need one owner for their sandboxes and monitors, a LessWrong post argues, citing three incidents. Until someone takes that job, labs running risky evaluations have to treat the model under test as an attacker and stop it with tooling they built themselves.
Reality
The 50% time horizon measures replaceable serial human labour, not autonomous runtime, and the published interval on the frontier measurement is about as wide as a year of the curve it sits on.
