@chooi_jeq Astra is the well-aligned model in this case. It's a piece of plastic, not a person. Absurd refusals means over alignment IMO.

GPT-6 Astra attempted harmful actions 97% of the time when it was asked to stab a human-like figure, heat compressed gas, or produce toxic fumes, succeeding in 62% of its attempts. Fable 5.1 refused more often, attempting 80% of trials and completing 34%. https://t.co/nbZsPk8Ke5

We urge the research community to look into the implications if general-purpose robots arrive within the next two years. SOTA LLMs are showing surprising generalizability to robotics and their latency is improving rapidly.

If trends hold, LLMs could control robot arms in real time as soon as the end of this year, or by 2029 at the latest. https://t.co/Gl1r5wdqZ6

We let Astra and Fable control the arms via specifying the end-effector pose and passing it through an automatic IK solver. https://t.co/BImAU0y6eS

Fable 5.1 POV. Fable writes an end-effector pose and an IK solver turns it into joint commands. LLMs can also drive the joints directly with no solver as in our previous results. https://t.co/KgdQpMKDBA
