FrontierThe story, in brief
KV Sharing, MHC, and Compressed Attention
Three architectural shifts reshaping how LLMs process tokens—and what it means for your inference costs.
The KeyNews take
Why it matters
Recent developments in KV sharing, multi-head latency compression, and compressed attention represent material shifts in LLM architecture efficiency. These optimizations directly impact inference speed, memory footprint, and cost-per-inference—critical metrics for production deployments.
