TurboQuant is a KV cache compression technique for LLMs, using normalization, rotation, codebooks, and indices to shrink memory 3-4x with minimal quality loss.

How does TurboQuant save GPU memory?

It encodes high-dim vectors into tiny index sequences via shared codebooks, storing norms separately—reversible on decode, perfect for dynamic inference caches.

Will TurboQuant work with Llama or Mistral models?

Yes, it's framework-agnostic; integrates with serving engines like vLLM, boosting context and speed on NVIDIA/AMD GPUs.

⚡ Key Takeaways

TurboQuant compresses KV caches 3-4x using restaurant-style codebooks, rotations, and quantization—saving gigabytes on GPUs. 𝕏
Simple, reversible math: norm + indices pack vectors from 16+ bytes to ~3, with tiny errors. 𝕏
Unlocks longer contexts and faster inference for local LLMs, predicting edge AI boom like MP3 did for music. 𝕏
