Cheapest GPU to run ThinkingCap-Qwen3.6-27B by precision
Full precision. Best quality, highest memory.
8-bit quantized. ~2x smaller, minimal quality loss.
4-bit quantized. ~4x smaller, runs on smaller GPUs.
Inference vs fine-tuning ThinkingCap-Qwen3.6-27B
Inference only holds the model weights plus a KV cache, so it is the cheapest setup. LoRA fine-tuning adds a small adapter and roughly 50% more memory. Full fine-tuning holds gradients and optimizer state on top of the weights, which is about 4x the inference footprint, so it often needs multiple GPUs even when inference fits on one. For ThinkingCap-Qwen3.6-27B, an on-demand L40S 48GB instance covers inference and LoRA, while a full fine-tune needs several times that memory and often spans multiple GPUs.
