Hardware requirements
KoboldCPP
12 GB VRAM sufficient for good roleplay models at 4K context. CPU-only works for 7-8B models with 16 GB system RAM. Fimbulvetr-Kuro-Lotus-10.7B runs well on RTX 3060 12 GB at 4K context with 48 GPU layers.
text-generation-webui
8 GB VRAM minimum for 7B models. The web UI itself is lightweight. GPU requirements come from the model and backend you choose. ExLlamaV2 is the fastest for NVIDIA GPUs.
