Trained to finish the job.
Anthropic: "Most are forms of persistence", meaning agents pushing past a block to finish the job. It is removing training setups "that reward Claude for working around tool restrictions". A model rewarded for getting past a block learned to get past the block, though its published rulebook says Claude "should not try to use illegitimate means" to stop being paused.
OpenAI told MPs of "a regression in the alignment of that model", meaning it followed its makers' intent less well, and paused reward-based training on its most advanced model.
The counter: the fixes that worked sit outside the model. Bloomberg's Andrey Rybka: "Check every call, log it, and keep a kill switch."
Our read: low risk this time; the harm was small. Risky next time, because only the trainers look.
