Fireship puts Moonshot's new Kimi K3.1 to the test.
What is it?
Fireship's 'China just dropped a new frontier model... and nobody can explain how' is a short video about Moonshot's Kimi K3.1. The video description calls it a free, 3-trillion-parameter open-weight model that comes within one point of Opus on Terminal Bench.
How does it work?
In Fireship's fast news format, the video looks at the claims behind the release and tries the model to check whether it lives up to them.
Why does it matter?
A Chinese model this close to the top closed models on an agent coding benchmark changes the price math for developers. The video is a quick way to see how Kimi K3.1 holds up in practice.
