Frequently Asked Questions

Can I run FINAL-Bench_Darwin-28B-Opus-GGUF Q5_0 on a consumer GPU?
Yes! At 21.71 GB VRAM required, a single high-end consumer GPU like the RTX 4090 (24GB) can handle this workload. You can also use multiple GPUs for tensor parallelism.
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 FINAL-Bench_Darwin-28B-Opus-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 Q5_0 quality good enough for production?
Q5_0 is suitable for specialized use cases. Check community benchmarks for specific quality metrics.
