Kimi K3 is live on Riven.

Kimi K3 landed Tuesday. 2.8 trillion parameters, a 1M-token context window, and within 24 hours it took the top spot on LMArena's frontend code arena.

The weights are not public yet — Moonshot has promised them for July 27. Today K3 is API-only.

As of now, kimi-k3 is live on Riven at Moonshot's exact list price — $3 per million tokens in, $15 out. Transparent per-token pricing. Same OpenAI-compatible endpoint as the 160+ other models we serve.

The whole migration is one line:

model: "kimi-k3"

The benchmark crown moves every six weeks. Your prompts, agents, and workflows should not move with it. Build on the gateway, not the leaderboard.

Riven is self-hosted, single-tenant AI for enterprises that demand control, compliance, and performance. Your infrastructure or ours.
