Why other calculators give a different number
A parameters × bits ÷ 8 estimate puts Q4_K_M at roughly 123.46 GiB. The real file is 132.39 GiB, because a quantization is a mixture and some tensors are always kept at higher precision.

Questions people ask
- How much VRAM does Qwen3-VL-235B-A22B-Instruct need?
- Q4_K_M is exactly 142,154,076,192 bytes (132.39 GiB) in weights. Add the KV cache, which depends on your context length, plus roughly half a gigabyte of runtime overhead.
- How large is Qwen3-VL-235B-A22B-Instruct's KV cache?
- 5.88 GiB at 32K context with an f16 cache, computed per layer. Quantizing the cache to q8_0 roughly halves it, which is often the difference between a context length fitting and not.
- Is Qwen3-VL-235B-A22B-Instruct a mixture-of-experts model?
- Yes — 128 experts, 8 routed per token. Every expert must be resident, but only the routed ones are read per token, which is why its memory requirement and its speed behave very differently.
- Which quantization of Qwen3-VL-235B-A22B-Instruct should I use?
- Q4_K_M is the usual default. Pick the largest quantization that fits your card at the context you actually need — the table above gives exact sizes for every one published.
