Can I run DeepSeek-V4-Flash on AMD Ryzen AI Halo (128GB)?
No. DeepSeek-V4-Flash needs ~179.7 GB even at Q4_K_M, but AMD Ryzen AI Halo (128GB) only has ~96 GB usable.
Needs ~179.7 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 83.7 GB: DeepSeek-V4-Flash needs roughly 179.7 GB at Q4_K_M and AMD Ryzen AI Halo (128GB) leaves only about 96 GB usable for a model. The lightest tracked hardware that runs DeepSeek-V4-Flash is the Apple M3 Ultra (256GB) at 256 GB. See DeepSeek-V4-Flash on Apple M3 Ultra (256GB).

FAQ
Can AMD Ryzen AI Halo (128GB) run DeepSeek-V4-Flash?
No. DeepSeek-V4-Flash needs ~179.7 GB even at Q4_K_M, but AMD Ryzen AI Halo (128GB) only has ~96 GB usable.
How much memory does DeepSeek-V4-Flash need?
AMD Ryzen AI Halo (128GB) does not have enough memory. At Q4_K_M the weights are ~174.87 GB; with KV cache and runtime overhead, budget ~179.7 GB at a 4k context. It is a Mixture-of-Experts model (284B total / 13B active), so all experts must stay in memory; memory tracks total params, not active params.
What is the best tool to run DeepSeek-V4-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.
