Largest open release to date (~2.8T MoE); the current open frontier-substitute pick.
Kimi K3 is among the largest open releases to date — a mixture-of-experts around 2.8 trillion parameters — and it adds native vision to the open-weight frontier, with a roughly 1M-token context. For teams seeking an open substitute near the closed frontier, it is one of the current picks.
Two caveats shape the read. Its benchmark figures are vendor-reported rather than independently verified, so we hold its exact standing as provisional. And the license is a modified MIT rather than fully permissive — worth reading closely before commercial deployment. Hosted pricing varies by provider, and the model's sheer size makes full self-hosting demanding.
For organizations that want open weights with vision and are comfortable validating capability themselves, K3 is a serious option; those needing independently verified performance may prefer DeepSeek V4-Pro until third-party numbers land.
FIELD NOTE — Adds native vision. Hosted price varies by provider.
