Moonshot AI · Frontier · Open weights
Kimi K3
Moonshot's 2.8-trillion-parameter flagship, which Moonshot describes as the first open-source model at that scale, with native image understanding and a 1M-token window. Aimed at long-horizon coding and knowledge work.
Model ID: kimi-k3
What that means
A worked example
Per-token pricing is hard to feel. Take a moderately chatty production workload: 100 calls a day, roughly 10,000 tokens in and 2,000 out each time. On Kimi K3 that comes to about:
$180 / month
Before caching, batching or volume discounts, all of which move this number a long way. Illustrative only.
