Kimi K2 Thinking is CRAZY... (HUGE UPDATE)
now waiting for a 20B distillation

Kimi K2 Thinking Is The BEST Open Source Model - First Look & Testing
Kimi's writing is always so good. It's human-like and rarely detected in AI detector.

Kimi K2 explained in 5 minutes
Quick correction: the recommended hardware on MoonShot AI's site for running the k2-base is 8 units of h100 for the quantized version so the cost is at least 8x than what i calculated here. It's still a bit behind in feasibility but the point remains that the gap will change. I apologize for the miscalculation!
