How much VRAM does Llama 4 Maverick 17B (128E) need?

About 254.2 GB at Q4_K_M with 4K of context and batch 1, rising to roughly 260.0 GB at 32K. That figure is weights plus KV cache plus a 10% activation buffer, calculated from the model's architecture rather than measured on a card.

Will Llama 4 Maverick 17B (128E) run on a 512GB GPU?

Yes — at Q4_K_M and 4K context it needs about 254.2 GB, which leaves 257.8 GB spare on a Mac M5 Ultra 512G. That is the smallest card in this index that clears it comfortably; 1 of 63 do.

Which quantization of Llama 4 Maverick 17B (128E) should I use?

Q4_K_M has the lowest published quality loss (2.2%), and Q4_K_M is the level most people run. All 2 levels in the index are Q4_K_M, Q3_K_M.

Running Llama 4 Maverick 17B (128E) locally

At Q4_K_M and 4K of context, Llama 4 Maverick 17B (128E) needs about 254.2 GB — 230.4 GB of weights, 0.75 GB of KV cache and a 23.1 GB activation buffer. The smallest card in this index that clears that comfortably is the Mac M5 Ultra 512G at 512 GB, and 1 of the 63 cards here do. These are calculated figures, not measurements: the estimate stops counting a card as comfortable at 88% of its VRAM, which is roughly the room a desktop session needs.

What longer context costs

Going from 4K to 32K adds about 5.25 GB, taking the total to 260.0 GB. Weights do not move with context — only the KV cache does, and it grows linearly, so this is the number to watch when planning for long documents. The model's native window is 1024K; holding all of it at Q4_K_M would need about 465 GB.

Which build to download

This index only tracks Llama 4 Maverick 17B (128E) in GGUF, across 2 levels (Q4_K_M, Q3_K_M). Q4_K_M carries the lowest published perplexity loss at 2.2%. The fastest level measured here is Q3_K_M at 10 tok/s on an RTX 4090, batch 1. GGUF runs on llama.cpp and Ollama across NVIDIA, AMD and Apple silicon; AWQ and GPTQ target vLLM on CUDA and ROCm; EXL2 is ExLlamaV2 and CUDA only.
