Frequently Asked Questions
How much VRAM does Gemma 4 E2B IT Uncensored need?
Gemma 4 E2B IT Uncensored requires 3.4 GB of VRAM at Q4_K_M, or 10.6 GB at BF16. Full 131K context adds up to 0.7 GB (4.1 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 5.1B × 4.8 bits ÷ 8 = 3.1 GB
KV Cache + Overhead ≈ 0.3 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.
KV Cache + Overhead ≈ 1 GB (at full 131K context)
VRAM usage by quantization
What's the best quantization for Gemma 4 E2B IT Uncensored?
For Gemma 4 E2B IT Uncensored, Q4_K_M (3.4 GB) offers the best balance of quality and VRAM usage. Q5_K_M (4.0 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 2.5 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run Gemma 4 E2B IT Uncensored on a Mac?
Yes — MacBook Air 13" M3 (8 GB) and 145 other Macs can run Gemma 4 E2B IT Uncensored. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 3.4 GB of usable unified memory (RAM minus macOS overhead).
Can I run Gemma 4 E2B IT Uncensored locally?
