Can an M3 Ultra run Codestral-22B-v0.1?

The answer

llm-speed has not measured Codestral-22B-v0.1 on M3 Ultra itself yet, so there is no llm-speed verdict. 1 community-submitted run exists (fastest 47.5 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.

llm-speed has not measured this pair itself, so there is no llm-speed verdict or fastest quant. The rows above are community-submitted, not measured by llm-speed.

VRAM: not recorded for these runs. The VRAM calculator gives an estimate (predicted, not measured).
