Qwen3-Next-80B-A3B-Instruct-REAM

This model is a compressed version of Qwen/Qwen3-Next-80B-A3B-Instruct. 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/. 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 >=95% 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.

Feb 27, 2026: Qwen3-Next-80B-A3B-Instruct-REAMv2

• upd ver was compressed with more code data. Specifically, the ratio between c4, math and coding data (see https://bknyaz.github.io/blog/2026/moe/) is 0.0, 0.7, 0.3.
• C=32 (number of experts in groups) instead of C=16, which we found to work better.
• MTP layer is also compressed and added to the model following the original Qwen3-Next-80B-A3B-Instruct model. MTP was tested with --speculative-config '{"method":"qwen3_next_mtp","num_speculative_tokens":2}' and, on GSM8K, the performance was within 1%.

The v2 model here is compressed the same way as bknyaz/Qwen3-Coder-Next-REAM, except for MTP which is not available in Qwen3-Coder-Next models.
