Researchers demonstrate that LLM providers can systematically inflate token counts billed to users, with hidden reasoning tokens inflatable by up to 1,469% without detection. The core issue stems from a fundamental audit paradox: providers control both the tokenizer and execution, making verification impossible without independent verification mechanisms like trusted execution attestation or cryptographic proofs.

A research paper reveals that cloud-based LLM providers have financial incentives to misreport token usage and overcharge users, with current pay-per-token pricing mechanisms offering no transparency or proof. While transparency about the generative process makes undetected overcharging difficult, researchers developed an algorithm demonstrating that providers can still significantly overcharge at lower costs than their gains, and propose a character-count-based pricing model to eliminate these perverse incentives.
