Moonshot AI released Kimi K3 as an open-weight 2.8tn-parameter model with 104bn parameters active per token. The system selects 16 of 896 experts, supports a one-million-token context and claims 2.5 times K2's scaling efficiency. Its published results include 88.3 on Terminal-Bench 2.1 and 94.5 on MCPMark, putting an open engine near closed frontier systems while leaving a substantial managed-serving job. The edition connects K3 to Satya Nadella's model-portability warning, Microsoft's JavaScript and TypeScript work on Windows, Nvidia's Open Secure AI Alliance, multi-model vulnerability scanning, a $1bn Verizon fiber deal and RTX 50 price increases of up to 59%.

The Call: By October 31, 2026, at least one of AWS, Azure, Google Cloud, Databricks or Cloudflare will list Kimi K3 as a fully managed production model, including hosted weights and a supported endpoint rather than a customer-operated cluster recipe. Settles by October 31, 2026.
