About
Moonshot AI's Kimi K3 is the largest open-weight model ever released — 2.8 trillion parameters with only 16 experts firing per query. Independent benchmarks rank it fourth, not first, and the full weights drop July 27th with no public safety discussion. Jet breaks down what the engineering actually means, what the press release is hiding, and why the high API price is the strategy, not the problem.
