China just shipped the largest open-weight AI model ever built — 2.8 trillion parameters — and it reportedly edges out Claude and GPT-5.
The brief
Moonshot's Kimi K3 pairs record open-weight scale with a decoding method ~6.3× faster at million-token context. The bigger story is strategic: frontier-grade AI you can download and run — not just rent from an API — is now a two-front race between open labs (largely from China) and the closed frontier labs.
Takeaway
If you're tracking where AI is heading, watch the open-weight releases — that's where "frontier capability you can actually own and run" is being decided.
