Frequently Asked Questions
- How much VRAM does Qwen3 14B Uncensored need?
Qwen3 14B Uncensored requires 9.5 GB of VRAM at Q4_K_M, or 30.2 GB at BF16. Full 41K context adds up to 6.4 GB (15.9 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 14.8B × 4.8 bits ÷ 8 = 8.9 GB
KV Cache + Overhead ≈ 0.6 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 7 GB (at full 41K context)
VRAM usage by quantization
Q4_K_M9.5 GBQ4_K_M + full context15.9 GB- Can NVIDIA GeForce RTX 4090 run Qwen3 14B Uncensored?
Yes, at Q8_0 (15.4 GB) or lower. Higher quantizations like BF16 (30.2 GB) exceed the NVIDIA GeForce RTX 4090's 24 GB.
- What's the best quantization for Qwen3 14B Uncensored?
For Qwen3 14B Uncensored, Q4_K_M (9.5 GB) offers the best balance of quality and VRAM usage. Q5_K_S (10.8 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 6.9 GB.
