EXAONE-4.5-33B
LGAI-EXAONE/EXAONE-4.5-33BEXAONE-4.5-33B at Q4_K_M is exactly 20,047,839,424 bytes (18.67 GiB / 20.05 GB) — an effective 4.669 bits per weight, not the nominal 4. Its KV cache at 32K is 2.84 GiB, not the 8.00 GiB a flat formula predicts.

48 of 64 layers cache only a 4,096-token window rather than the full context, on a period of 4. Figures assume the default configuration; --swa-full disables the saving entirely.

Will it run on your card?
Why other calculators give a different number
A parameters × bits ÷ 8 estimate puts Q4_K_M at roughly 17.99 GiB. The real file is 18.67 GiB, because a quantization is a mixture and some tensors are always kept at higher precision. The larger discrepancy is the cache: a flat formula gives 8.00 GiB at 32K context where the real figure is 2.84 GiB, because most of this model's layers cache a fixed window rather than the whole context.
Architecture
Questions people ask
- How much VRAM does EXAONE-4.5-33B need?
- Q4_K_M is exactly 20,047,839,424 bytes (18.67 GiB) in weights. Add the KV cache, which depends on your context length, plus roughly half a gigabyte of runtime overhead.
- How large is EXAONE-4.5-33B's KV cache?
- 2.84 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.
- Which quantization of EXAONE-4.5-33B 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.
