How much VRAM does YuYu1015-Ornith-1.0-9B-abliterated need?

UD-Q4_K_M is exactly 6,197,388,288 bytes (5.77 GiB) in weights. Add the KV cache, which depends on context length, plus roughly half a gigabyte of runtime overhead.

How large is YuYu1015-Ornith-1.0-9B-abliterated's KV cache?

1.00 GiB at 32K context with an f16 cache, computed per layer from the model's architecture. Quantizing the cache to q8_0 roughly halves it.

24 of 32 layers use linear attention, which keeps a fixed-size recurrent state instead of a per-token cache. Those layers do not grow with context at all — treating them as ordinary attention, as a flat formula does, overstates this model's cache by roughly 4.0× at long context.

Why other calculators give a different number

A parameters × bits ÷ 8 estimate puts UD-Q4_K_M at roughly 4.93 GiB. The real file is 5.77 GiB, because a quantization is a mixture and some tensors are always kept at higher precision.

Questions people ask

How much VRAM does YuYu1015-Ornith-1.0-9B-abliterated need?: UD-Q4_K_M is exactly 6,197,388,288 bytes (5.77 GiB) in weights. Add the KV cache, which depends on your context length, plus roughly half a gigabyte of runtime overhead.
How large is YuYu1015-Ornith-1.0-9B-abliterated's KV cache?: 1.00 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 YuYu1015-Ornith-1.0-9B-abliterated 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.
