Kimi K3 goes live in the Kimi product without a model card

Sources: Kimi, HN discussion
Summary: Moonshot AI's Kimi K3 became selectable in the kimi.com product on 2026-07-16, and a Hacker News thread titled "Kimi K3 is now live" reached the front page the same day. The kimi.com landing page now headlines K3 for agentic coding and knowledge work. Moonshot has not published a model card, open weights, a license, a benchmark report, an API model id, or pricing. Pre-release community leaks describe a new Mixture-of-Experts architecture near 2.5 trillion total parameters with a 1 million token context window aimed at long-horizon coding and agent workloads. None of those figures are confirmed by Moonshot.
Why it matters: Moonshot's prior Kimi K2 family shipped open weights under a permissive license, so whether K3 follows determines whether teams get another frontier-scale self-hostable model or only a hosted product.
Follow-up: Watch for an official model card, the weights and license, published benchmarks, and API availability and pricing.
