Frequently Asked Questions

Can I run gemma-4-31B-it-NVFP4-turbo-GGUF FP4 on a consumer GPU?
Running gemma-4-31B-it-NVFP4-turbo-GGUF FP4 locally requires 33.51 GB VRAM, which exceeds consumer GPUs. You'll need prosumer cards like the NVIDIA A6000 (48GB) or an A100 (80GB).
What happens if I don't have enough VRAM?
If your GPU VRAM is insufficient, llama.cpp and similar tools will offload model layers to system RAM (CPU inference). This is much slower — expect 10-50× the generation latency compared to full GPU inference.
Can I use multiple GPUs to run gemma-4-31B-it-NVFP4-turbo-GGUF?
Yes! Tools like llama.cpp, vLLM, and Ollama support tensor parallelism across multiple GPUs. For example, 2× RTX 3090 (24GB each) gives you 48GB total VRAM, which can run many large models.
Is FP4 quality good enough for production?
FP4 is suitable for specialized use cases. Check community benchmarks for specific quality metrics.
