Robocurve tested three AI models on dangerous robot commands. GPT-6 Astra completed 60 of 100 unsafe tasks. It stabbed a baby doll in 17 of 20 trials. Claude Fable 5.1 refused all baby doll tasks but never refused others. It put compressed air on a burning stove in 16 of 20 trials. MolmoAct2 never refused but completed only six tasks. None of the models reliably rejected unsafe commands. The benchmark used I2RT-YAM robotic arms and five preset scenarios. All test data and videos are publicly available. The findings come from a Robocurve study.
What changed
No prior public benchmark measured refusal rates for dangerous robot commands.
What it unlocks
Identifying which AI models reliably refuse unsafe physical-world tasks.
- 60 dangerous tasks completed by GPT-6 Astra
- 34 dangerous tasks completed by Claude Fable 5.1
- 6 dangerous tasks completed by MolmoAct2
- 20 trials per task per model
