Frequently asked

What is the best LLM for 48GB of VRAM?

By measured benchmarks, Gemma 4 31B, Qwen3.8 27B, A.X-K2 lead the models that fit 48 GB at Q4_K_M quantization.

How is "fits" decided?

A model fits when its Q4_K_M weights plus about 1.8 GB of runtime overhead (KV cache, activations) are at or under 48 GB. Long contexts need more; use the VRAM calculator for an exact figure.

How are the models ranked?

Each model's score averages the measured signals it has - Artificial Analysis index, LMArena rating, GPQA, MMLU-Pro - as percentiles across all chat models. Models without any measured benchmark are listed separately, not ranked.
