Can I run Ornith 1.5 35B-A3B on 32GB RAM Laptop (CPU/iGPU only)?

Compatibility verdict VRAM threshold engine

Yes, it runs usable speed

Yes. Ornith 1.5 35B-A3B runs on 32GB RAM Laptop (CPU/iGPU only) at Q4_K_M (~22.4 GB of ~28 GB usable).

Needs ~22.4 GB Device usable ~28 GB

Runs at Q4_K_M using ~22.4 GB of ~28 GB usable.

That figure is at a 4k context and moves about ±15% as context length changes. 32GB RAM Laptop (CPU/iGPU only) leaves ~5.6 GB of headroom.

FAQ

Can 32GB RAM Laptop (CPU/iGPU only) run Ornith 1.5 35B-A3B?

Yes. Ornith 1.5 35B-A3B runs on 32GB RAM Laptop (CPU/iGPU only) at Q4_K_M (~22.4 GB of ~28 GB usable).

How much memory does Ornith 1.5 35B-A3B need?

32GB RAM Laptop (CPU/iGPU only) has room to spare. At Q4_K_M the weights are ~20.22 GB; with KV cache and runtime overhead, budget ~22.4 GB at a 4k context. It is a Mixture-of-Experts model (35B total / 3B active), so all experts must stay in memory; memory tracks total params, not active params.

What is the best tool to run Ornith 1.5 35B-A3B 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.
