Frequently Asked Questions
- How much VRAM does GLM 5 Abliterated need?
GLM 5 Abliterated requires 456.5 GB of VRAM at Q4_K_M, or 1512.0 GB at BF16. Full 203K context adds up to 384.7 GB (841.3 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 753.9B × 4.8 bits ÷ 8 = 452.3 GB
KV Cache + Overhead ≈ 4.2 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 389 GB (at full 203K context)
