They have a 512gb ram option but pricey.

Have you tried any other models with this M3 Ultra?

The 512gb model would have to use a lobotomized quant like q_2 or q_1, and you would still be waiting 3-5 minutes to process context lengths in the 32,000-64,000 token range.

Apple's GPUs are just not very fast for inference. I'd stick to the smaller 7b-18b parameter range or MOE models like Qwen if you want a usable inference speed.

  • Looks like that's a good idea for now. Yeah 3-5 mins is not practical use.

    Any thoughts on M5?

    They may be soon releasing a M5 model with mac studio/mini.

  • NVIDIA DGX Spark a good option?

    $4,699.00

    But looks like we may need a NVIDIA AI Enterprise - DGX Spark License
