"it'll barely run on an M5 Max "

The max version I could order now with 128 GB?

If so, the price for local inference would be 12 000 € vs 500 000 € for a B300.

There's also the 2x spark way, which should be ~8k eur? Someone down the thread reported ~60tps for 2x sparks. That's totally usable for local inference.

You can also do 2x 6kPRO in a workstation, for ~20k.

For the same performance, one could even go about 50% cheaper with 16 channel ddr4 + a rtx3090 for prompt processing.

But still, even for mid level projects API is orders of magnitude cheaper, since you don't need to set it up and maintain it.

The memory bandwidth of the 2x RTX Pro 6000 Blackwell setup will be 10x higher, which should have an equivalent effect on the generated tokens per second.

Currently the 3bit (and 2 bit) quant on DGX spark (on one of them) and the M5 Max should just start. Right now. (I'm hoping to get an M5 Max delivered on monday, let's see if it happens this time. It's 2+ months since I ordered now)

The 4 bit quant technically fits (there's a 127 GB version) but ... obviously that's not going to work. It is so close though, surely someone will a way to do it.

I'm running a useful quantization of the previous version of Deepseek-V4-Flash -- quite well but with so much fan noise -- on a MacBook Pro M5 Max with 128 GB.

500k is for the 8x B300 version. Which is the only one you can buy atm. But technically a B300 card is more like 60k, just impossible to get.
