Researcher: Looped Transformers add no real recurrence, just tied-parameter depth

savvyRL · x · 2026-09-03

Researcher savvyRL pushes back on the recent hype around Looped Transformers: no matter how many loops you run, the transformer remains inherently feedforward. The only "recurrence" introduced is depth recurrence with tied parameters, which is functionally the same as making the model deeper. He notes the idea dates back to Dehghani et al., 2019, and argues the only genuine recurrence is carrying information forward in time. The thread aims to correct the community's tendency to treat looping as a magical fix.
