Can I run GLM-5.3-Flash on AMD Ryzen AI Halo (128GB)?

Compatibility verdict VRAM threshold engine

No, not enough memory would not load

No. GLM-5.3-Flash needs ~204.8 GB even at Q4_K_M, but AMD Ryzen AI Halo (128GB) only has ~96 GB usable.

Needs ~204.8 GB Device usable ~96 GB

Needs ~204.8 GB even at Q4_K_M, but only ~96 GB is usable.

That figure is at a 4k context and moves about ±15% as context length changes.

The gap is about 108.8 GB: GLM-5.3-Flash needs roughly 204.8 GB at Q4_K_M and AMD Ryzen AI Halo (128GB) leaves only about 96 GB usable for a model. No single tracked device has enough memory; GLM-5.3-Flash needs a multi-GPU or high-memory rig.

FAQ

Can AMD Ryzen AI Halo (128GB) run GLM-5.3-Flash?

No. GLM-5.3-Flash needs ~204.8 GB even at Q4_K_M, but AMD Ryzen AI Halo (128GB) only has ~96 GB usable.

How much memory does GLM-5.3-Flash need?

AMD Ryzen AI Halo (128GB) does not have enough memory. At Q4_K_M the weights are ~199.71 GB; with KV cache and runtime overhead, budget ~204.8 GB at a 4k context. It is a Mixture-of-Experts model (320B total / 18B active), so all experts must stay in memory; memory tracks total params, not active params.

What is the best tool to run GLM-5.3-Flash on Windows?

LM Studio for a simple setup; Ollama (CUDA) for the most speed. AMD GPUs run via Vulkan/ROCm at roughly half CUDA throughput. NVIDIA is the smooth path on Windows.

Weights are measured from GGUF files; KV cache and overhead are computed, so totals can vary ~15% with context and runtime. Any tok/s is a bandwidth estimate. See methodology.
