CShorten30 · x · 2026-08-06

A developer has released a sub-6B sparse activation AI model built using a brand new 'fusion' architecture. The model fuses weights from Liquid AI's LFM2.5-2.6B and Alibaba's Qwen3.6-35B-A3B.

According to the creator, this fused model is only about a fifth of the size of the original Qwen model but is capable of achieving near-equivalent performance. Two additional models (26B and 12B) based on this architecture are reportedly in the works.
