WEKA's Val Bercovici: KV Cache, DeepSeek V4, HBF, SLC vs QLC NAND, CXL, NVLink, Tokenomics
SHOW NOTES
Vik welcomes Val Bercovici from Weka to discuss the rapidly evolving landscape of AI memory and storage. Val explains how Weka's architecture leverages high-bandwidth networks to make storage faster than motherboard DRAM. They dive into KV cache optimizations, the future of NAND flash tiers, and the role of CXL in AI inference. The episode concludes with a look at predictive memory offloading and the AI flywheel.
