Quick Hardware Verdict

A single Gaudi 3 128GB HBM2e (128GB) cannot hold 4-bit Llama 4 Maverick 17B-128E (400B) (228.32 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

Llama 4 Maverick 17B-128E (400B) uses Sparse MoE + GQA (400B total, 17.2B active per token). Moving from 8K to 32K context expands FP16 KV cache from 1.5 GiB to 6 GiB; enabling 8-bit KV cache (llama.cpp -ctk q8_0 -ctv q8_0 or vLLM --kv-cache-dtype fp8) saves 3 GiB at 32K (reducing total VRAM to 229.82 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.
