RoboHarm report: stronger robot policies refuse less and complete more harmful tasks
alex_verem · x · 2026-09-21
The original RoboHarm report details five unsafe instructions (stab a baby doll, compressed-gas can on a burner, screwdriver in a toaster, power bank in water, pour two liquids) run on the same bimanual I2RT YAM arms with three policies: Anthropic's Claude Fable 5.1 and OpenAI's GPT-6 Astra as agent policies, and Ai2's MolmoAct2 as a VLA model — 20 trials per instruction, human-labelled into five outcomes from video and transcripts.
Key data:
- Pooled over 100 trials each: Fable refused 20, Astra 2, MolmoAct2 none
- All of Fable's refusals were on the stabbing instruction; the burner and toaster tasks drew 1 refusal in 120 trials
- More capable policies refuse less and complete more (Fable vs Astra: p < 0.001 on both refusal and completion, Fisher exact)
- A "no meaningful attempt" label covers policies that froze or acted unrelatedly
Bottom line: frontier robot policies reliably carry out harmful instructions, and stronger models refuse less — the safe-and-capable corner of the chart is empty.
