Moonshot AI · Coding and reasoning models
Using Kimi K3 with a coding agent
Moonshot's 2.8T-parameter model — the first open 3T-class release — with a 1M-token context and native vision, built for agent runs measured in hours rather than turns.
Not wired up
Not yet, and it's the priciest candidate here at $3 in / $15 out per million tokens, which puts it near frontier pricing rather than the usual Chinese-model discount. That can still pay off on long agent runs, where a cheaper model burns more tokens getting to the same place. It won't pay off on autocomplete.

List price from the vendor's own API — cache-miss input and output. Third-party hosts are often cheaper, and cached reads change the real number.
What it takes to use it
Weights went public on 26 July 2026, so there are two routes: Moonshot's own API, or a host serving the open weights. Both expose an OpenAI-compatible endpoint, which is all a coding agent needs. One note for anyone searching: this is Moonshot's K series. MiniMax's models are the M and H series, and the two get mixed up constantly.
