Doing some googling against DeepSeek for which more stats are openly available: We need

~508GB+ Uncompressed memory

~256Gb with 3-bit compression (about 3 bits per weight)

~128Gb with 1-bit compression (1.58 to 2.3 bits per weight)

So uncompressed is still about an order of magnitude out of most home systems' reach, but with compression it's not far off.
