At that level of quantization / distillation, smaller models like phi-2 (q&a) and wavecoder-6.7b (code-gen) might be preferable over QLoRAd ones: https://huggingface.co/microsoft/phi-2 > 2bit is pretty damn terrible Wait till you go hybrid [0] or even 1bit [1] [0] https://github.com/efeslab/Atom [1] https://github.com/IST-DASLab/qmoe

Text from the Abstract: Mixture-of-Experts (MoE) architectures offer a general solution to the high inference costs of large language models (LLMs) via sparse routing, bringing faster and more accurate models, at the cost of massive parameter counts. For example, the SwitchTransformer-c2048 model has 1.6 trillion parameters, requiring 3.2TB of accelerator memory to run efficiently, which makes practical deployment challenging and expensive. In this paper, we present a solution to this memory problem, in form of a new compression and execution framework called QMoE. Specifically, QMoE consists of a scalable algorithm which accurately compresses trillion-parameter MoEs to less than 1 bit per parameter, in a custom format co-designed with bespoke GPU decoding kernels to facilitate efficient end-to-end compressed inference, with minor runtime
