Kimi K3 Performance
Kimi K3 is Kimi’s most capable model to date, with 2.8 trillion parameters.
On the GDPval-AA v2 leaderboard, Kimi K3 scores 1687. The benchmark evaluates AI models on real-world tasks across 44 occupations and 9 major industries; Kimi K3 ranks behind only Claude Fable 5 Max and GPT-5.6 Sol Max, and ahead of Claude Opus 4.8 Max at 1600.
The model’s performance is impressive, but its pricing is also high.
One thing to consider, though: reasoning efficiency matters directly for how expensive a model actually is in real use. GPT’s models are extremely reasoning efficient, and some Claude models like Fable at lower effort are as well. So if Sol spends 10K reasoning tokens to do something (at $30/1M) vs Kimi K3 that spends 50K reasoning tokens, Sol would win on cost effectiveness.
Conclusion
Kimi K3 is a powerful model with impressive performance, but its high pricing may be a barrier for some users.
