Can an M3 Ultra run Qwen3-Next-80B-A3B-Instruct?
llm-speed has not measured Qwen3-Next-80B-A3B-Instruct on M3 Ultra itself yet, so there is no llm-speed verdict. 1 community-submitted run exists (fastest 80.3 tok/s at 4-bit on mlx); community-submitted, not measured by llm-speed, so it gives no verdict.
1 signed run on llm-speed. Single-request decode speed in tokens per second; the short-chat workload unless noted. This run is community-submitted (signed on the submitter's own machine, not measured by llm-speed, and not used for llm-speed verdicts). Verdicts and headline numbers use only llm-speed's own runs and fit tests.
