IMMACULATE: Detecting LLM API Provider Cheating
Story
Detects economically motivated deviations — model substitution (provider swaps in cheaper model), quantization abuse, and token overbilling — without model internals access. Uses verifiable computation on a small fraction of requests. Critical for anyone relying on third-party LLM APIs. arXiv 2602.22700
