Phi-3-mini-4k-instruct

This model declares a 2,048-token sliding window, but we could not establish which layers use it. Its architecture publishes the layout as a per-layer array inside the model file rather than as a period in config.json, and we have not yet ingested that array.

A flat context × layers × heads figure would be substantially too high, so we are not showing one. This is tracked as a known gap rather than filled with a guess.

A parameters × bits ÷ 8 estimate puts Q4_K_M at roughly 2.00 GiB. The real file is 7.83 GiB, because a quantization is a mixture and some tensors are always kept at higher precision.

How much VRAM does Phi-3-mini-4k-instruct need?

Q4_K_M is exactly 8,404,011,936 bytes (7.83 GiB) in weights. Add the KV cache, which depends on your context length, plus roughly half a gigabyte of runtime overhead.

Which quantization of Phi-3-mini-4k-instruct 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.
