KV cache gets QAT too: why this model beats others at fp4 KV cache
stochasticchasm · x · 2026-09-11
An interesting technical nugget: per the shared breakdown, the model in question applied quantization-aware training (QAT) to its KV cache as well — which explains why it performs better than other models at fp4 KV cache precision. Notable engineering insight for low-precision inference deployment.
