Qwen2.5-Coder-7B-Instruct-Ghidra-v2

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.

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.

How much VRAM does Qwen2.5-Coder-7B-Instruct-Ghidra-v2 need?

Q4_K_M is exactly 4,683,074,208 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 Qwen2.5-Coder-7B-Instruct-Ghidra-v2'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 Qwen2.5-Coder-7B-Instruct-Ghidra-v2 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.
