Prefill Once, Fan Out: KV Snapshot Sharing for Multi-Agent LLM Pipelines

# AI Systems Just Got Smarter at Reusing Work When multiple AI assistants need to process the same information, they currently waste time by each one starting from scratch. A new technique called "KV snapshot sharing" lets them share the preparation work, similar to how you'd photocopy a document once instead of having five people read the original separately. This could make AI systems faster and cheaper, especially when deploying multiple assistants to handle related tasks.
