GLM 4.7 — Hardware Requirements & GPU Compatibility
ChatFunctions
GLM 4.7 is an earlier generation of Zhipu AI's GLM foundation model series, featuring a mixture-of-experts architecture with approximately 358 billion total parameters. It delivers strong performance on reasoning, language understanding, and bilingual Chinese-English tasks while being significantly more manageable to run locally than its GLM 5 successor. For users with multi-GPU setups, GLM 4.7 offers a practical balance between capability and hardware requirements within the GLM model family.

Frequently Asked Questions
How much VRAM does GLM 4.7 need?
GLM 4.7 requires 215.6 GB of VRAM at Q4_K_M, or 717.3 GB at BF16. Full 203K context adds up to 31.5 GB (247.1 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 358.3B × 4.8 bits ÷ 8 = 215 GB
KV Cache + Overhead ≈ 0.6 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.
KV Cache + Overhead ≈ 32.1 GB (at full 203K context)
VRAM usage by quantization
Can NVIDIA GeForce RTX 5090 run GLM 4.7?
No — GLM 4.7 requires at least 99.2 GB at IQ2_XXS, which exceeds the NVIDIA GeForce RTX 5090's 32 GB of VRAM.
What's the best quantization for GLM 4.7?
For GLM 4.7, Q4_K_M (215.6 GB) offers the best balance of quality and VRAM usage. Q4_K_L (220.1 GB) provides better quality if you have the VRAM. The smallest option is IQ2_XXS at 99.2 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run GLM 4.7 on a Mac?
Yes — Mac Pro M2 Ultra (128 GB) and 14 other Macs can run GLM 4.7, the smallest at IQ2_M. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 215.6 GB of usable unified memory (RAM minus macOS overhead), from Mac Studio (M3 Ultra, 256GB).
Can I run GLM 4.7 locally?
Yes — GLM 4.7 can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is GLM 4.7?
At Q4_K_M, GLM 4.7 can reach ~44 tok/s on AMD Instinct MI350X. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = 1000 ÷ (active GB ÷ (bandwidth GB/s × efficiency) × 1000 + layers × routing ms)
Mixture-of-Experts: just the active experts get read for each token, along with a fixed routing cost per layer.
Example: NVIDIA B300 → 21.4 GB active ÷ (8000 × 0.65) = 4.12 ms, plus 92 layers × 0.055 ms = 5.06 ms, so 1000 ÷ 9.18 ms = ~109 tok/s
Estimated speed at Q4_K_M (215.6 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of GLM 4.7?
At Q4_K_M, the download is about 215.00 GB. The full-precision BF16 version is 716.68 GB. The smallest option (IQ2_XXS) is 98.54 GB.
Which GPUs can run GLM 4.7?
No single consumer GPU has enough VRAM to run GLM 4.7 at Q4_K_M (215.6 GB). Multi-GPU or professional hardware is required.
Which devices can run GLM 4.7?
2 devices with unified memory can run GLM 4.7 at Q4_K_M (215.6 GB), including Mac Studio (M3 Ultra, 256GB), Mac Studio (M3 Ultra, 512GB). Apple Silicon Macs use unified memory shared between CPU and GPU, making them well-suited for local LLM inference.
