Kimi K3.1 draws Fireship a fine horse, then animates it badly
Jeff Delaney's Code Report weighs China's free, three-trillion-parameter model, the fight over distillation, and a homemade test built on hooves.
Why this story? One of the most watched videos since yesterday, with 951,180 views.
China just dropped a new frontier model... and nobody can explain how
Things we can learn from the video

- 0:00An anonymous Chatbot Arena model called Kibitz is revealed as Moonshot AI's Kimi K3.1 Pro.
- 0:27Kimi K3.1 Pro is a three-trillion-parameter open-weight model with strong reported scores.
- 0:54Anthropic and OpenAI accuse Chinese companies of distilling their frontier models; the host jokes it is a human right.
- 2:09Terminal-Bench and SWE Marathon results put Kimi close to closed models such as Opus.
- 2:46Moonshot removed cybersecurity exploit data on purpose to reduce the model's hacking abilities.
- 4:23On ThoroughBench, Kimi builds a detailed 3D horse, but animates it with crude mesh warping.
Mystery model, unmasked. An anonymous entry called "Kibitz" turned up on Chatbot Arena, and it turned out to be Kimi K3.1 Pro from Moonshot AI. That reveal opens Fireship's latest Code Report, which drew about 950,000 views in its first nine hours.
The pitch, as Jeff Delaney lays it out: a free, open-weight model with three trillion parameters that, on the Terminal-Bench coding test, comes within a point of Anthropic's Opus. A week earlier the channel was test-driving Google's new model against GPT-6 and Opus. This time the challenger comes from China, and the title asks how.
Part of the answer is the argument hanging over the whole industry. Anthropic and OpenAI have accused Chinese companies of distillation, training their own models on the outputs of frontier ones. Delaney does not hide where his sympathies lie. "Now, I believe distillation is a fundamental human right," he says, before describing how the big labs see it: "Grand Theft Auto-Complete," a practice they have spent millions trying to stop. He also notes a less expected choice: Moonshot deliberately stripped cybersecurity exploit data from its training to blunt the model's hacking skills.
Then the leaderboards give way to ThoroughBench, Delaney's own test of how well a model can build an interactive 3D horse with Three.js. Kimi produces a handsome, detailed animal. Then it has to move. The motion comes from simple mesh warping, and Delaney's verdict is short: "The animations are absolutely terrible." The on-screen caption puts it more bluntly.
The horse has taken over the comments. Many viewers want it made an official benchmark for every new model, and others joke that they follow the channel mainly for the equine updates. The episode closes with a sponsored segment for the design tool Mobbin.

We need an oficial horse benchmark score for all AIs
@forealoveSee it on YouTubeLast time i was this early AI was fancy autocomplete
@fff-kd8kgSee it on YouTubeWell you forgot to add "make no mistakes". No wonder the horse moves like that.

@ikegru4346See it on YouTubeTHE TRUST ME BRO BENCHMARKS 😂
@AdamsOyifiSee it on YouTubeThe reason the 3D model of the horse looked so real is that Kimi uses Tripo to generate the 3D model and then simply displays it as a .glb file. That’s why it couldn't rig it properly, resulting in a horrible walk animation.
