Rumor: GLM 5.5 to Hit 2.5T-3.5T Parameters With Looped Transformer Architecture

Rumors suggest Zhipu's next model, GLM 5.5, will have 2.5T-3.5T parameters along with significant architecture changes. In its August HKEX interim filing, Zhipu said it had validated the idea of Looped Transformers in preliminary experiments.

Commentator @scaling01 predicts a "cambrian explosion of dirty loopers" next year, with many models adopting looped architectures. All of this remains unconfirmed rumor and personal speculation.
