China's Open Models Go Commercial: The Koda Signal, 2026-09-19

Koda Signal daily AI briefing for 2026-09-19.

In this episode: • China's Open Models Go Commercial: Moonshot's Kimi K3 claims the largest open-source parameter count yet, and Plexara scores it and Z.AI's GLM-5.3 at 44, the top of the open-weight tier. The same week Moonshot connected Kimi to Wind, S&P, and EDGAR feeds for ICBC, CITIC Securities, and E Fund, while MiniMax signed HUMAIN, Genspark, and Singtel. The pattern mirrors OpenAI's Astra for Law: vertical data plus sovereign customers, not benchmarks alone, is where the revenue lands. • Trump's One-Day Power Sweep: In a single day Trump claimed a Greenland security deal with Denmark, signed the Graham Sanctioning Russia and Iran Act granting up to 100% tariff authority over buyers of Russian energy, and barred CNN, MS Now, and Politico from the White House. India, which rejected the tariff threat earlier this week, is the most exposed large buyer. Meanwhile the IAEA reported a drone strike on a Kursk nuclear plant cooling tower, with the reactor still operating normally.
