Frequently Asked Questions
- How much VRAM does Gemma 4 E2B IT Ultra Uncensored Heretic need?
Gemma 4 E2B IT Ultra Uncensored Heretic requires 3.4 GB of VRAM at Q4_K_M, or 10.6 GB at BF16. Full 131K context adds up to 3.5 GB (6.9 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)
KV Cache + Overhead ≈ 3.8 GB (at full 131K context)
