Niklas(@niklaslenz_ai):256 GB class: DeepSeek-V4.1-Flash-1017 on 2 DGX Sparks built a voxel world in 59.7 minutes. @MiaAI_lab's 2-Spark recipe and EXL3 quant, TensorFold engine by @ashxhart, model by @deepseek_ai. Build test: the model works as an agent. One prompt, one try, no help. Browser check: 8/10 Tokens written: 131,268 Speed benchmark: 67 tok/s decode (separate run, thinking off) Agent settings: top-p 0.95, as in Mia's recipe. Answer limit: raised to the model card's 262,144 tokens, the recipe's server default is lower. My test gate sent a keepalive every 30 s so the connection stayed open. Open: 47 of 400 MMLU-Pro answers ran past our short answer limit and count as wrong. Open: 61 of 198 GPQA answers did the same. Open: memory tested up to 128K, speed there not measured. Really good. Almost as good as the 4-Spark world. Play the world in your browser. Every number, the exact command and the raw output:
