Four forces created exponential pressure on context storage: model size growing, context length exploding (4K→1M+ tokens), multi-turn conversations, and concurrent users.
The Brutal Math
A million-token context window requires orders of magnitude more memory than 4K. Multiply by millions of concurrent users with persistent agent sessions.
NVIDIAs Answer: Bluefield 4
150TB of KV cache storage per unit — extending memory from on-chip HBM to network-attached storage.
Strategic Implication
Companies solving context persistence win the agentic era. Memory architecture became as strategic as model architecture.
