Abstract
The paper discusses a method to reduce unnecessary reasoning time in models by using a halt vector to internalize causal interpretability findings.
Reality Card
Core Claim
The halt vector intervention reduces reasoning time by about 25% while maintaining accuracy across five unseen benchmarks.
Method / Result
The halt removes about a quarter of the thinking at held accuracy across five unseen benchmarks.
Limitations
Installing the halt vector intervention is complex and may corrupt off-axis dimensions relied upon by downstream readers.
