510GB DeepSeek V4.1 Flash runs at ~4 tok/s on one RTX 3090
Project Maya splits the 510GB model across GPU core layers and hot experts, system RAM and on-demand SSD reads, reaching about 4 tokens per second on an RTX 3090 with 64GB RAM.

DeepSeek V4.1 Flash 1017 is a 510 GB download. @ItsmeAjayKV runs it on one RTX 3090 with 64 GB of RAM. Project Maya splits it three ways: the card holds the core layers and the busiest experts, RAM holds more experts, and the rest is read from the SSD as needed. It is slow, about 4 tokens a second, but it works on a gaming PC. Where each GB goes on your own PC, card by card and RAM size by RAM size, is what our Project Maya calculator shows. http://vramcalculator.com/project-maya-calculator/
