TurboQuant: Redefining AI efficiency with extreme compression

TurboQuant: Redefining AI efficiency with extreme compression

AI summary

Google Research released TurboQuant, compressing the KV cache to three bits without loss of model accuracy or training and fine-tuning, alongside the QJL and PolarQuant methods.

Selection record

AdmittedSum of both 124 ≥ twice the threshold 120

Source tier
Official, first-hand; this tier's threshold is 60
Pre-filter
passed:Google Research发布AI向量压缩算法TurboQuant
Why it was chosen
Official compression mechanisms and benchmark results provide evidence for assessing viable KV-cache compression approaches.

A model scores each item twice, independently, against one written standard, out of 100. An item is admitted only when the two scores add up to twice the threshold. The threshold is set per source tier.
