99. 97% cost reduction on context reads. 1. 69µs retrieval. Drop-in with LangChain, CrewAI, AutoGen. The problem every multi-agent system hasYour agents are making tool calls to read context that hasn't changed. Each one costs:800ms+ round-trip latencyScaffold tokens burned on the same boilerplateAPI cost, repeated per agent, per requestWith 5 agents and 3 context reads each:$1,387/year on reads alone.
