Nemotron Quantization Details Update
nrehiew_ · x · 2026-07-13
The author provides additional context on a quantization strategy related to **Nemotron**: - The **last 15%** of the components are kept in **bf16**. - The **shared expert** is also retained in bf16. - The next goal is to compress the representation range to **±4** to reduce the maximum relative error. - For activations and weights, multiple schemes are computed simultaneously, selecting the one with the **minimum representation error**. - However, this approach is **more computationally expensive**, necessitating reliance on kernel-level optimizations. This is essentially a research and training note focused on engineering implementation details.
