Frequently Asked Questions

How much VRAM does Keys GLM 5.3 EXL3 Abliterated need?

Keys GLM 5.3 EXL3 Abliterated requires 108.9 GB of VRAM at Q4_K_M, or 363.1 GB at BF16.

VRAM = Weights + KV Cache + Overhead

Weights = 165.0B × 4.8 bits ÷ 8 = 99 GB

KV Cache + Overhead ≈ 9.9 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.

Can I run Keys GLM 5.3 EXL3 Abliterated on a Mac?

Yes — Mac Studio (M3 Ultra, 96GB) and 20 other Macs can run Keys GLM 5.3 EXL3 Abliterated, the smallest at Q2_K. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 108.9 GB of usable unified memory (RAM minus macOS overhead), from Mac Pro M2 Ultra (128 GB).

Can I run Keys GLM 5.3 EXL3 Abliterated locally?

Yes — Keys GLM 5.3 EXL3 Abliterated can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Keys GLM 5.3 EXL3 Abliterated?

At Q4_K_M, Keys GLM 5.3 EXL3 Abliterated can reach ~44 tok/s on AMD Instinct MI350X. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = (bandwidth GB/s ÷ model GB) × efficiency

Example: NVIDIA B200 → 8000 ÷ 108.9 × 0.65 = ~48 tok/s
