Context Window Optimization via KV-Cache Passing

+++ Multi-agent systems have been hilariously inefficient, forcing each agent to retokenize prior context. Researchers finally noticed this waste and built caching systems that slash redundant computation by 29x, proving sometimes the best innovations solve problems practitioners have been quietly fuming about. +++

What if LLM agents passed KV-cache to each other instead of text? I tried it -- 73-78% token savings across Qwen, Llama, and DeepSeek

"If you've used multi-agent setups with LangChain, CrewAI, AutoGen, or Swarm, you've probably noticed: every agent re-tokenizes and re-processes the full conversation from scratch. Agent 3 in a 4-agent chain is re-reading everything agents 1 and 2 already chewed through. When I measured this across Q..."
