MiMo 2.6 keeps a plain architecture — is strong RL enough without novel modules?
BagComprehensive79 · reddit · 2026-09-22
A Redditor examining the newly released MiMo 2.6 architecture on Hugging Face notes it looks strikingly simple compared to recent open models: no Gated DeltaNet, no mHC or similar modules, no engram — just an ordinary architecture. They speculate the strong performance comes from RL training and ask whether simple architecture plus good RL is enough.
