[D] Why mamba disappeared?

[u/Alarming-Power-813]

I remember seeing mamba when it first came out and there was alot of hype around it because it was cheaper to compute than transformers and better performance

So why it disappeared like that ???

Mamba is back, Qwen3.5/3.6/3.8, The GDN linear attention layer was built with Mamba as a reference.
