Can an M3 Ultra run DeepSeek-R1-0528-Qwen3-8B?
llm-speed has not measured DeepSeek-R1-0528-Qwen3-8B on M3 Ultra itself yet, so there is no llm-speed verdict. 1 community-submitted run exists (fastest 116.8 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.
