8× Faster Inference
TurboQuant computes attention up to 8× faster than standard 32-bit models on H100 GPUs — so you get responses in real time, at any scale.
6× Less Memory
The KV cache is compressed by at least 6× with no degradation in output quality, drastically cutting infrastructure costs.
Zero Accuracy Loss
Compressed down to just 3 bits — with no retraining, no fine-tuning, and no trade-off in model performance.
