Local Mac Studio test: DeepSeek V4 Flash finishes 5x faster than Qwen 3.8 Flash Next

A user running Qwen 3.8 Flash Next and DeepSeek V4 Flash locally on a 128GB M1 Ultra Mac Studio asks how others choose between them. On the Artificial Analysis Intelligence Index, Flash Next scores just above GPT 5.4/5.5 xhigh and DeepSeek V4 just below GPT 5.5 high — but in practice Flash Next takes dramatically longer to finish tasks; the index chart suggests DeepSeek completes 5 tasks in the time Flash Next does 1. The author isn't bashing Flash Next (currently 2h5m into a deep task with it) but will stick with Qwen 3.8 27B as a daily driver since it uses less of the machine, leaving room for image gen work. A real-world illustration that near-tied benchmarks can hide huge throughput gaps on local hardware.
