VRAM Requirements by Quantization & Context Length
All values in gigabytes (GB). Calculated using the KV-cache formula with model-specific head fractions. “–” means the context length exceeds this model’s maximum context window. Lower quantization = less VRAM but slightly reduced output quality.
| Quantization | 4K ctx | 8K ctx | 32K ctx | 128K ctx |
|---|---|---|---|---|
| Q4_K_M | 430.2 GB | 430.5 GB | 432.6 GB | 440.8 GB |
| Q5_K_M | 502.2 GB | 502.5 GB | 504.6 GB | 512.8 GB |
| Q6_K | 578.5 GB | 578.9 GB | 580.9 GB | 589.2 GB |
| Q8_0 | 747.9 GB | 748.3 GB | 750.3 GB | 758.6 GB |
| FP16 | 1406.3 GB | 1406.6 GB | 1408.7 GB | 1416.9 GB |
Weights = 754B params × GGUF bits per weight (Q4_K_M ≈ 4.9); plus runtime overhead; plus fp16 KV cache from config.json: MLA latent of 576 values per layer — ~88 KB per token at short context. Same engine as the Can I Run LLM calculator.
Best GPU for GLM-5 by Budget
Recommendations assume Q4_K_M quantization at 4K context unless stated otherwise. Higher-end quantizations or longer context windows require more VRAM — consult the table above.
- Under $500 (Entry GPU) Not feasible at this budget
- $500–$1,000 (Mid-Range GPU) Not feasible at this budget
- $1,000–$3,000 (High-End GPU) Not feasible at this budget
- $3,000+ (Workstation / Cloud) Multi-GPU / cloud (Q4_K_M)

How to Run GLM-5 Locally
Before downloading, verify your GPU has sufficient VRAM using the table above. Insufficient VRAM will cause the model to fall back to CPU offloading, which is significantly slower.

Strengths and Use Cases
Strong at coding, math, reasoning, content writing. Runs locally with the right GPU — see the VRAM table above for exact requirements.
When choosing a local LLM, GLM-5 is worth considering if your workload aligns with its design goals. As a Dense Transformer architecture from Zhipu AI, it offers a distinct trade-off between compute efficiency and capability. Its dense architecture provides consistent, predictable performance across a wide range of tasks. Whether you are building a local AI pipeline, experimenting with self-hosted chat, or running automated workflows, understanding this model's hardware envelope helps you plan infrastructure realistically.
For deployment, start with the Q4_K_M quantization unless you have headroom for higher precision. Q5_K_M and Q6_K offer improved output quality at the cost of additional VRAM. FP16 is generally only practical on high-VRAM workstation GPUs or cloud instances. Always verify context length requirements before selecting a quantization — longer context windows multiply KV-cache memory consumption significantly, as shown in the VRAM table above.
