Same Weights, Same Prompt, Different Triage Level
A developer running a 4-bit medical-triage LLM on different hardware configurations encountered unexpected output variations. The same model weights and prompt produced different triage levels when run on a laptop GPU versus a CPU. This divergence, attributed to differences in hardware-level arithmetic execution and floating-point rounding, highlights the challenges of ensuring deterministic outputs from quantized models across diverse hardware.
