TurboQuant
No written verdict yet. Here is what commenters said.
Why people recommend it
“People have successfully used TurboQuant to quantize model weights”
“I have been getting good results with IQ4_NL and TurboQuant at 4bits”
Show 3 more
“it's so cool, so we started to integrate them”
“TurboQuant [1] looks pretty promising”
“This sounds great! TurboQuant does KV cache compression using quantization via rotations”
Caveats and dissent
“people should read turboquant's open review comments”
“the Turboquant debaucle is entirely on Google doing incredible amount of academic misconduct”
Show 2 more
“TurboQuant looks like a vibe-laundered implementation of EDEN quantization”
“TurboQuant is known across the industry to not be state of the art”

tl,dr: there is an allegedly better alternative, and it's already implemented everywhere: https://github.com/VectorDB-NTU/RaBitQ-Library#rabitq-in-industry

Actually, they published a year ago. Recent was being on official Google blog. https://arxiv.org/abs/2504.19874 https://research.google/blog/turboquant-redefining-ai-efficiency-with-extreme-compression/
