Frequently Asked Questions
How much VRAM does Qwen27b Abliterated Fable MTP need?
Qwen27b Abliterated Fable MTP requires 17.8 GB of VRAM at Q4_K_M, or 59.4 GB at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 27B × 4.8 bits ÷ 8 = 16.2 GB
KV Cache + Overhead ≈ 1.6 GB (at 2K context + ~0.3 GB framework)
Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.
VRAM usage by quantization
Can NVIDIA GeForce RTX 4090 run Qwen27b Abliterated Fable MTP?
Yes, at Q5_K_M (21.2 GB) or lower. Higher quantizations like Q6_K (24.5 GB) exceed the NVIDIA GeForce RTX 4090's 24 GB.
What's the best quantization for Qwen27b Abliterated Fable MTP?
For Qwen27b Abliterated Fable MTP, Q4_K_M (17.8 GB) offers the best balance of quality and VRAM usage. Q5_K_M (21.2 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 12.6 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run Qwen27b Abliterated Fable MTP on a Mac?
Yes — Mac Mini M5 Pro (24 GB) and 106 other Macs can run Qwen27b Abliterated Fable MTP. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 17.8 GB of usable unified memory (RAM minus macOS overhead).
Can I run Qwen27b Abliterated Fable MTP locally?
