CPU-Based Classifiers Can Match GPU Performance for LLM Safety at Fraction of Cost, Research Shows
A new study from researchers Majhi, Vasudev, Gupta, Dhruv, Singh, Advait, Barker, and Kumar evaluates CPU-based classifiers for LLM safety, finding they match transformer GPU models on in-distribution data at roughly one-fifth the deployment cost. The paper introduces GuardChain, a three-stage pipeline that routes prompts to the cheapest capable stage, resolving 80% of in-distribution traffic on CPU alone.
