CAT-Q: Cost-efficient and Accurate Ternary Quantization for LLMs

In this paper, we present CAT-Q, Cost-efficient and Accurate Ternary Quantization, for compressing and accelerating LLMs. Unlike existing state-of-the-art ternary quantization methods that rely on data-intensive and costly quantization-aware training to mitigate severe performance degradation, CAT-Q is a simple yet effective post-training quantization scheme that is readily applicable to LLMs with diverse architectures and model sizes.

Low-Rank Ternary Adaptation for Fine-Tuning Transformers

The paper introduces a ternary multiplicative adaptation technique that enables fine‑tuning of ternary transformers without dequantization. By representing discrete weight updates as a low‑rank Kronecker factorization of two small ternary matrices applied element‑wise, the method preserves the ternary domain and allows direct merging of adaptation weights. Experiments on six language and vision models, including ternarized LLaMA‑3 and ViT‑B/16, show that the approach recovers most of the performance lost to quantization and outperforms existing low‑bit and ternary baselines.
