1. **[8-bit Optimizers via Block-wise Quantization](https://md.research.elamur.ai/free/en/papers/dettmers-2021-8-bit-optimizers-block-wise/)** *(2021 · 177 citations)* Stateful optimizers such as Adam and SGD with momentum store per-parameter gradient statistics. These statistics take up a large share of training memory (33–75% by the authors' estimate), which limits how big a model can fit on given hardware. Dettmers et al. show that these statistics can be kept in 8 bits instead…
2. **[The case for 4-bit precision: k-bit Inference Scaling Laws](https://md.research.elamur.ai/free/en/papers/dettmers-2022-case-4-bit-precision-k/)** *(2022 · 119 citations)* Quantizing an LLM shrinks its memory use and, at small batch sizes, its latency. This raises a practical question: for a fixed budget of total model bits, is it better to run a larger model at low precision or a smaller one at higher precision? Dettmers and Zettlemoyer frame this as inference scaling laws that relate…
