Creator to test GB300-class machine with 1TB RAM tomorrow, asks for fine-tuning test ideas
zxtech · reddit · 2026-11-03
A hardware content creator will get hands-on time with an ET900N (GB300-class) machine packing 1TB of RAM (750GB LPDDR5X plus HBM) tomorrow to make content, and is asking the community what to run.
Planned inference tests include quantized NVFP4 builds of DeepSeek V4.1 Flash 1017, GLM 5.3 Flash, Qwen 3.8 FN, and MiniMax M3.1 Flash. For small-model high-concurrency scenarios, Qwen 3.8 27B + muse glimmer; for image/video generation, Qwen 2.1 and MiniMax H3. The biggest open question is how to benchmark fine-tuning, where he'd most appreciate suggestions. He'll share results afterward.
