arXiv: REAM: Merging Improves Pruning of Experts in LLMs

Qwen3-Coder-Next-REAM

This model is a compressed version of Qwen/Qwen3-Coder-Next. It is obtained by reducing the number of experts in each MoE layer from 512 to 384. This reduction is achieved by the REAM method described in https://bknyaz.github.io/blog/2026/moe/.

Compared to other models obtained in this collection, more code data is used in the calibration data during pruning/merging to better preserve original's model coding abilities. Specifically, the ratio between c4, math and coding data (see https://bknyaz.github.io/blog/2026/moe/) is 0.0, 0.3, 0.7. The calibration data used here is the same as in [Qwen3-Coder-Next-REAP](https://huggingface.co/SamsungSAILMontreal/Qwen3-Coder-Next-REAP). Compared to other REAM models, here we used C=32 (number of experts in groups) instead of C=16, which we found to work better.

The compressed model has 60B params (120GB) instead of 80B (160GB) of the original model, reducing storage and GPU memory requirements by roughly 25%. At the same time, the model retains 100% (or very close) of the original model's performance on a variety of benchmarks (see Results section below). Additional efficiency optimization (e.g., quantization) can be added similarly to the original model.
