From White House plagiarism accusation to Amazon Bedrock: the full Kimi K3 timeline
ccerrato147 · x · 2026-11-02
A full-thread timeline of Kimi K3's journey from controversy to commercial rollout:
- Jul 16: Beijing's Moonshot AI releases Kimi K3; it tops Arena's web-coding leaderboard the same day, ahead of Claude Fable 5 — first freely downloadable model to do so.
- Jul 22: White House science adviser Michael Kratsios claims K3 was trained on Fable's answers; Moonshot denies. Treasury Secretary Bessent posts "open source is not open season on American IP."
- Jul 28: K3 available on Microsoft's AI platform via partner Fireworks AI.
- Aug: Reuters reports Moonshot asked Microsoft, Amazon and Google for up to 30% of their resale revenue.
- Sep: Amazon adds K3 to Bedrock.
Price is the hook: K3 writes tokens at $15/M vs Fable's $50, and Moonshot's Oct 23 model costs just $10 — a decisive factor for anyone running coding agents all day.
