How much VRAM does OREAL-DeepSeek-R1-Distill-Qwen-7B need?

Q4_K_M is exactly 4,683,073,856 bytes (4.36 GiB) in weights. Add the KV cache, which depends on context length, plus roughly half a gigabyte of runtime overhead.

How large is OREAL-DeepSeek-R1-Distill-Qwen-7B's KV cache?

1.75 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.

Why other calculators give a different number

A parameters × bits ÷ 8 estimate puts Q4_K_M at roughly 3.99 GiB. The real file is 4.36 GiB, because a quantization is a mixture and some tensors are always kept at higher precision.

Questions people ask

How much VRAM does OREAL-DeepSeek-R1-Distill-Qwen-7B need?: Q4_K_M is exactly 4,683,073,856 bytes (4.36 GiB) in weights. Add the KV cache, which depends on your context length, plus roughly half a gigabyte of runtime overhead.
How large is OREAL-DeepSeek-R1-Distill-Qwen-7B's KV cache?: 1.75 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 OREAL-DeepSeek-R1-Distill-Qwen-7B 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.
