Kimi K3: 2.8 Trillion Parameters, Weights Coming July 27
Moonshot AI announced Kimi K3, a 2.8 trillion parameter model available now via API, with open weights promised by July 27, 2026.
What it is
Kimi K3 is Moonshot AI's newest flagship model, described by the company as its most capable to date and pitched as the first "open 3T-class model", surpassing DeepSeek's 1.6T V4 Pro in parameter count.
What it does
Runs today through Moonshot's website and API; the weights themselves are not yet public and are scheduled for release by July 27, 2026.
Why it matters
It's a data point in the open-weight-model arms race between Chinese labs, relevant if you're evaluating self-hostable alternatives to closed models like GPT or Claude for cost or data-residency reasons, though there's nothing to run yet.
How to use it
Test it now via the Kimi API if you want early access; wait for the July 27 weights release if self-hosting is the goal.
