Eric Jang shares lessons from building AlphaGo from scratch

Eric Jang分享从零构建AlphaGo的经历与见解

Eric Jang spent several months implementing AlphaGo from scratch and says that in 2026, training a strong Go AI requires only a few thousand dollars in rented compute rather than DeepMind-scale resources.

Why it matters: All three HKR axes pass: the hook is a from-scratch AlphaGo rebuild, and K has concrete claims on months of work and few-thousand-dollar compute. It stays in 78-84 because this is a social post, not a model release or full paper.
