Why other calculators give a different number

A parameters × bits ÷ 8 estimate puts I1-IQ1_S at roughly 17.16 GiB. The real file is 6.82 GiB, because a quantization is a mixture and some tensors are always kept at higher precision.

false

This model declares a sliding window but sets use_sliding_window: false, so the window is not applied. Honouring the field without the flag understates KV for the whole family.

Questions people ask

How much VRAM does AReaL-boba-2-32B need?
I1-IQ1_S is exactly 7,323,841,760 bytes (6.82 GiB) in weights. Add the KV cache, which depends on your context length, plus roughly half a gigabyte of runtime overhead.
How large is AReaL-boba-2-32B's KV cache?
8.00 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 AReaL-boba-2-32B 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.
