GLM 4.5V — Hardware Requirements & GPU Compatibility
VisionGLM-4.5V is Z.ai's vision-language model built on its GLM-4.5-Air text foundation, a mixture-of-experts model with roughly 14.3 billion active parameters out of about 107.7 billion total. It continues the technical approach of GLM-4.1V-Thinking and covers image, video, and long-document understanding, GUI agent operation, complex chart parsing, and visual grounding, reaching state-of-the-art results among similarly sized models on 42 public vision-language benchmarks. A Thinking Mode toggle lets it trade fast responses for deeper step-by-step reasoning, mirroring the same switch in the GLM-4.5 text model. Given its scale, it needs a multi-GPU workstation once quantized. Context length is 65,536 tokens. It is released under the MIT license, permitting unrestricted commercial and research use. It was published in August 2025, succeeding the smaller GLM-4.1V-9B-Thinking model.

Frequently Asked Questions
- How much VRAM does GLM 4.5V need?
GLM 4.5V requires 65.1 GB of VRAM at Q4_K_M, or 215.8 GB at BF16. Full 66K context adds up to 4.0 GB (69.0 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 107.7B × 4.8 bits ÷ 8 = 64.6 GB
KV Cache + Overhead ≈ 0.5 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 4.4 GB (at full 66K context)
VRAM usage by quantization
Q4_K_M65.1 GBQ4_K_M + full context69.0 GB- Can NVIDIA GeForce RTX 5090 run GLM 4.5V?
Yes, at IQ2_XXS (30.1 GB) or lower. Higher quantizations like IQ2_XS (32.7 GB) exceed the NVIDIA GeForce RTX 5090's 32 GB.
- What's the best quantization for GLM 4.5V?
For GLM 4.5V, Q4_K_M (65.1 GB) offers the best balance of quality and VRAM usage. Q5_K_S (74.5 GB) provides better quality if you have the VRAM. The smallest option is IQ2_XXS at 30.1 GB.

- Can I run GLM 4.5V on a Mac?
GLM 4.5V requires at least 30.1 GB at IQ2_XXS, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.
- Can I run GLM 4.5V locally?
Yes — GLM 4.5V can run locally on consumer hardware. At Q4_K_M quantization it needs 65.1 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is GLM 4.5V?
At Q4_K_M, GLM 4.5V can reach ~91 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 ÷ 65.1 × 0.65 = ~239 tok/s
Estimated speed at Q4_K_M (65.1 GB)
~239 tok/s~239 tok/s~191 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of GLM 4.5V?
