Frequently Asked Questions
- How much VRAM does Phi 4 Mini Reasoning Abliterated need?
Phi 4 Mini Reasoning Abliterated requires 2.5 GB of VRAM at Q4_K_M, or 8.4 GB at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 3.8B × 4.8 bits ÷ 8 = 2.3 GB
KV Cache + Overhead ≈ 0.2 GB (at 2K context + ~0.3 GB framework)
VRAM usage by quantization
Q4_K_M2.5 GB- What's the best quantization for Phi 4 Mini Reasoning Abliterated?
For Phi 4 Mini Reasoning Abliterated, Q4_K_M (2.5 GB) offers the best balance of quality and VRAM usage. Q5_K_M (3.0 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 1.8 GB.
