Tinygrad refreshes Tinybox with an 'old' EPYC CPU running DDR4 RAM to feed four AMD 9070XT — slaps a $11,000 price tag on a new 'computer for deep learning'

Share

An $11K box built on older EPYC + DDR4 feeding multiple GPUs is a reminder that for many workloads, GPU density and price/perf beat bleeding-edge CPUs. If you’re a scrappy AI team, you may get more leverage from tuned, commodity-heavy rigs than chasing the latest server SKUs.

A look at OpenAI's safety concerns over loop transformers before shipping its next major model; Microsoft accidentally confirmed GPT-6.1 Sol uses the technique

Loop transformers moving into a flagship model like GPT-6.1 Sol means architectural choices are now a safety and governance surface, not just a performance tweak. If you’re building on frontier models, expect more variance in behavior across versions and bake in evals and rollback plans tied to model family, not just version number.
