⚠️ Stop pretraining your looped Transformer with a separate KV cache per recursion! In our recent preprint, we show that *memory sharing* not only saves memory but is also a net-positive inductive bias! Less memory, same flops, higher quality. 🔗 arxiv.org/abs/2610.02383 🧵

Simple, straightforward, and just work well: looping with no KV overhead, and this also gives you a gradients highway that makes backprop work much better

We released tickets to our waiting list (as of yesterday). If you were on the wait list, please check your email. Tickets that are not claimed will be re-distributed. The wait list remains open, so sign up if interested
