Inside Kimi K3: How a 2.8T Frontier Model Was Built
Moonshot’s Kimi K3 report shows that building a 2.8‑trillion‑parameter model now leans heavily on data pipelines, compute budgeting, and an engineered mixture‑of‑experts architecture rather than novel algorithms. The 47‑page blueprint details the three incremental engineering tweaks that cut training cost by 2.5×, giving practitioners a concrete roadmap.
