SharedRequest: Privacy-Preserving Model-Agnostic Inference for Large Language Models (2026.acl-long)
Copied to clipboard
| Challenge: | Existing privacy-preserving inference methods sacrifice utility or efficiency, authors say . current approaches suffer a trilemma between privacy, utility, and efficiency, they say . |
| Approach: | They propose a model-agnostic framework for privacy-preserving LLM inference that reformulates privacy protection at the batch level rather than the individual-prompt level. |
| Outcome: | The proposed model-agnostic framework achieves 20% higher utility than previous models . it reduces query cost by up to 5 compared to non-batched inference . |
