When KV Cache Reuse Fails in Multi-Agent Systems: Cross-Candidate Interaction is Crucial for LLM Judges (2026.acl-long)
Copied to clipboard
| Challenge: | Multi-agent LLMs generate multiple candidate responses that are aggregated by an LLM judge. |
| Approach: | They propose to advocate KV cache reuse across partially shared contexts and report substantial speedups for generation agents. |
| Outcome: | The proposed reuse strategies weaken cross-candidate attention, especially for later candidate blocks, and highlight judge-centric inference as a distinct regime that requires dedicated, risk-aware system design. |
