The key takeaway isn’t just compression—it’s where the bottleneck shifts. KV cache has been dominating memory footprint in long-context inference, so reducing it changes the cost structure significantly. But it doesn’t remove the constraint entirely:

You’re trading memory bandwidth for additional compute (de/quantization isn’t free) Model weights and activation flows still sit in high-bandwidth memory At scale, efficiency gains often trigger more usage (classic Jevons paradox)

One implication that doesn’t get discussed enough: this could extend the useful life of existing GPUs (A100/H100 class) for inference workloads, especially for long-context applications.

Curious how people here see this playing out in production systems—does KV cache compression meaningfully change your infra decisions, or just shift optimization elsewhere?
