Frequently Asked Questions
- How much VRAM does Gemma 4 E4B IT Ultra Uncensored Heretic need?
Gemma 4 E4B IT Ultra Uncensored Heretic requires 5.3 GB of VRAM at Q4_K_M, or 16.5 GB at BF16. Full 131K context adds up to 13.9 GB (19.2 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 8.0B × 4.8 bits ÷ 8 = 4.8 GB
KV Cache + Overhead ≈ 0.5 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 14.4 GB (at full 131K context)
