arXiv:2606.17059v1 Announce Type: cross Abstract: Prefix caching can reduce LLM inference latency by reusing KV caches across requests with shared prompts, but cluster-scale reuse is challenging because caches are partitioned across nodes. We propose a decentralized, prefix-cache-aware routing scheme for peer-to-peer LLM serving. Each node maintains a local radix tree of its own cached prefixes and asynchronously refreshed estimates of peer caches using periodic anti-entropy. Requests are routed to the node with the longest estimated prefix match, without centralized coordination or KV-cache t
This development emerges as the scale of LLMs continues to grow, driving a need for more efficient and resilient inference infrastructure beyond traditional centralized cloud models.
A decentralized approach to LLM inference could significantly reduce operational costs, increase data privacy, and improve fault tolerance for AI applications, broadening accessibility.
The paradigm shifts from needing massive, centralized compute clusters for serving LLMs to potentially enabling a peer-to-peer network where individual nodes contribute to inference.
