Sakana AI's Takuya Akiba to unpack Kimi K3's architecture: how a 2.8T-param open model was built
tkasasagi · x · 2026-09-04
- Moonshot AI released Kimi K3 in July 2026 — among the largest open-weight models ever at 2.8 trillion parameters — matching top US models on blind-vote coding benchmarks.
- Sakana AI chief scientist Takuya Akiba (@iwiwi) will break down K3's internals in a free online event on Sept 29: technical elements like KDA and AttnRes, what actually drives LLM performance gains, and the design philosophy visible in the team's evolution from K2 to K3.
- The event, moderated by fukabori.fm's Iwase, already has 246 sign-ups — a rare public deep-dive into the architecture of a frontier Chinese open model.
