Quick Hardware Verdict

A single MetaX C500 64GB (沐曦曦云) (64GB) cannot hold 4-bit Mistral Large 4 (1T-A52B) (566.32 GiB at 8K) entirely in VRAM. Use multi-GPU tensor parallelism, offload layers to system RAM, or deploy on a larger cloud GPU.

KV Cache & Runtime Tuning

Mistral Large 4 (1T-A52B) uses Multi-head Latent Attention (MLA) MoE (1000B total, 52B active per token). Moving from 8K to 32K context expands FP16 KV cache from 0.63 GiB to 2.53 GiB; enabling 8-bit KV cache (llama.cpp -ctk q8_0 -ctv q8_0 or vLLM --kv-cache-dtype fp8) saves 1.26 GiB at 32K (reducing total VRAM to 566.96 GiB).

VRAM Scaling Across Context Windows (4K to 128K, 4-bit Weights)

Model weights remain constant while attention KV cache grows with context length and batch size.
