How much VRAM does Qwen2.5-14B-Instruct-abliterated-v2 need?

Its published quantizations range from 5.37 GiB to 14.62 GiB in weights alone, before KV cache and runtime overhead.

Qwen2.5-14B-Instruct-abliterated-v2 on GeForce RTX 3050

Can I run Qwen2.5-14B-Instruct-abliterated-v2 on a GeForce RTX 3050?

Q: Can I run Qwen2.5-14B-Instruct-abliterated-v2 on a GeForce RTX 3050?

No. No published quantization of Qwen2.5-14B-Instruct-abliterated-v2 fits a GeForce RTX 3050 at any context with q8_0 KV cache.

Not at these settings. No indexed quantization of Qwen2.5-14B-Instruct-abliterated-v2 fits GeForce RTX 3050 at any context we compute, with q8_0 KV. The smallest shipped quantization is 5.37 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 131,072-token window rather than the full context.
