Comprehensive Performance Study of TurboQuant KV-Cache Quantization
๐กData-driven analysis on which KV-cache quantization methods actually work for production.
โก 30-Second TL;DR
What Changed
FP8 is the best default for KV-cache quantization
Why It Matters
This research provides clear guidance for infrastructure engineers on balancing memory efficiency and model accuracy in production serving.
What To Do Next
Stick to FP8 for KV-cache quantization in production unless you are strictly memory-constrained, in which case evaluate 4bit-nc.
Who should care:Developers & AI Engineers
Key Points
- โขFP8 is the best default for KV-cache quantization
- โขTurboQuant k8v4 offers no significant advantage over FP8
- โข4bit-nc is viable for memory-constrained edge deployments
- โขk3v4-nc and 3bit-nc are unsuitable for production due to accuracy drops
