How much VRAM does functionary-medium-v3.2 need?

Its published quantizations range from 15.60 GiB to 69.83 GiB in weights alone, before KV cache and runtime overhead.

functionary-medium-v3.2 on GeForce RTX 3050

Can I run functionary-medium-v3.2 on a GeForce RTX 3050?

Q: Can I run functionary-medium-v3.2 on a GeForce RTX 3050?

No. No published quantization of functionary-medium-v3.2 fits a GeForce RTX 3050 at any context with q4_0 KV cache.

Not at these settings. No indexed quantization of functionary-medium-v3.2 fits GeForce RTX 3050 at any context we compute, with q4_0 KV. The smallest shipped quantization is 15.60 GiB in weights alone, against 5.58 GiB usable. CPU offload can still run it, slowly.

●From the file◐Predictedwhat these mean

Figures are GiB of total memory: weights plus KV cache plus compute buffer and backend overhead. Weights and KV are near-exact; the overhead term is modeled. Hover any cell for the breakdown.

Why other calculators disagree

A parameters × bits ÷ 8 estimate ignores two things that dominate at long context. First, the weights themselves are not the nominal rate — quantizations are mixtures, so the real file is consistently larger than the label implies. Second, most of this model's layers cache only a 8,192-token window rather than the full context.
