[AINews] How to Land a Job at a Frontier Lab (on Pretraining)
Latent Space says Vlad Feinberg’s pretraining job-prep notes reduce frontier-lab readiness to kernel-level performance work: derive Chinchilla laws, compare dense and MoE architectures, code the solution in JAX, then write a Pallas kernel that beats jax.lax.ragged_dot for F > D by fusing up/down projections.
Why it matters: HKR-H/K/R all pass: the career hook is strong and the prep list is concrete. It is not a model release or major product update, and the kernel-heavy angle keeps it at the lower featured band.
