Checked against

KV cache matches the GGUF header of unsloth/Qwen3-Coder-480B-A35B-Instruct-GGUF (opens in a new tab) (what llama.cpp allocates), October 10, 2026

VRAM by precision and context length

Weights plus the KV cache of one request (BF16 cache), in GiB. Add 1 to 3 GiB for the inference engine itself.

Qwen3-Coder 480B-A35B GGUF files

Exact size of each quantization in unsloth/Qwen3-Coder-480B-A35B-Instruct-GGUF (opens in a new tab), and the smallest GPU that runs it with llama.cpp, Ollama or LM Studio and an 8K-token context.

How many GPUs to run Qwen3-Coder 480B-A35B

Fewest GPUs that fit the weights plus one 8K-token request. Data-center GPUs use vLLM (90% of memory usable), the others llama.cpp. Several GPUs split the model with tensor or pipeline parallelism.

Cheapest way to run Qwen3-Coder 480B-A35B today

For each GPU: the fewest cards that fit Qwen3-Coder 480B-A35B with one 8K-token request, the most faithful weight format at that count, and the cheapest on-demand price (2026-10-10).

On-demand prices from RunPod, Vast.ai, Verda and Azure, checked every hour. Serving many users needs more KV cache, so more memory: size it in the calculator. Some links are affiliate links: StudioTV may earn a commission, at no extra cost to you.

KV cache: how memory grows with context

Architecture: MoE 160 experts · 62 layers, full attention (GQA, 8 KV heads × 128). Every layer keeps keys and values for every token (grouped-query attention), so the cache grows linearly with context. Only 35B parameters are active per token, but all 480B must sit in memory: VRAM depends on the total, speed on the active part.
