Transformer architecture hitting fundamental limits on test-time learning

Transformers are trained in the lab on static data but deployed in the real world where distributions shift; they cannot learn at test time beyond limited in-context learning or inefficient…

Fully automated AI research labs will accelerate architecture discovery velocity

Building labs where AI agents write kernels, run experiments, and iterate architectures daily — targeting 10-200 experiments per day vs. current human-limited pace — will dramatically short…

Autoregressive token generation inference inefficiency limits frontier AI accessibility

Current chain-of-thought scaling spends compute one token at a time, making inference costly and limiting frontier model access to a subset of users; architectural changes that increase com…

End-to-end co-optimization of pre-training and RL unlocks orders-of-magnitude efficiency

Current separate pre-training (perplexity minimization) and RL (chain-of-thought) pipelines are suboptimal; combining them with second-order optimizers like Shampoo and architecture-optimiz…

Kernel generation bottleneck blocks novel architectures; automating it unlocks new algorithmic space

Novel architectures require custom high-performance kernels (e.g., 60x speedup for QR factorization), but current models cannot write them; automating kernel generation via AI-assisted sear…
