Quick Hardware Verdict
A single RTX PRO 6000 Blackwell (96GB) cannot hold 4-bit MiniMax M2.5 (229B-A10B) (131.34 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
MiniMax M2.5 (229B-A10B) uses Sparse MoE + GQA (228.69B total, 10B active per token). Moving from 8K to 32K context expands FP16 KV cache from 1.94 GiB to 7.75 GiB; enabling 8-bit KV cache (llama.cpp -ctk q8_0 -ctv q8_0 or vLLM --kv-cache-dtype fp8) saves 3.87 GiB at 32K (reducing total VRAM to 133.28 GiB).
