AI model writes custom metal kernel in under an hour

A user on Reddit reported that the ds4 flash 0731 UD-IQ2_M model successfully wrote a custom metal kernel for Kimi K2 IQ1_0 in approximately 50 minutes. While the performance was described as "meh" but better than CPU, achieving about 4 tokens/s decode and 20 prefill for the K3 Q1_0 on a Mac Studio, the user found it impressive for a model of this size. The user also noted that the 2-bit unsloth version performed comparably to other quantizations, though they still preferred the 4-bit GLM 5.2. AI
