Google's TurboQuant Algorithm Promises 6x Reduction in AI Inference Memory Footprint

Google Research has announced TurboQuant, a lossless compression algorithm that reduces AI inference memory (KV cache) by at least 6x without impacting performance. The technology uses vector quantization methods called PolarQuant and QJL to address cache bottlenecks in AI processing. While the lab breakthrough has generated significant industry excitement and comparisons to DeepSeek's efficiency gains, it has not yet been deployed in production systems and only addresses inference memory, not training requirements.
