Can I run Laguna S 2.1 on AMD Radeon RX 7900 XTX (24GB)?
No. Laguna S 2.1 needs ~92.8 GB even at Q4_K_M, but AMD Radeon RX 7900 XTX (24GB) only has ~23 GB usable.
Needs ~92.8 GB even at Q4_K_M, but only ~23 GB is usable.
That figure is at a 4k context and moves about ±15% as context length changes.
The gap is about 69.8 GB: Laguna S 2.1 needs roughly 92.8 GB at Q4_K_M and AMD Radeon RX 7900 XTX (24GB) leaves only about 23 GB usable for a model. The lightest tracked hardware that runs Laguna S 2.1 is the Apple M4 Max (128GB) at 128 GB. See Laguna S 2.1 on Apple M4 Max (128GB).

FAQ
Can AMD Radeon RX 7900 XTX (24GB) run Laguna S 2.1?
No. Laguna S 2.1 needs ~92.8 GB even at Q4_K_M, but AMD Radeon RX 7900 XTX (24GB) only has ~23 GB usable.
How much memory does Laguna S 2.1 need?
AMD Radeon RX 7900 XTX (24GB) does not have enough memory. At Q4_K_M the weights are ~89.44 GB; with KV cache and runtime overhead, budget ~92.8 GB at a 4k context. It is a Mixture-of-Experts model (118B total / 8B active), so all experts must stay in memory; memory tracks total params, not active params.
What is the best tool to run Laguna S 2.1 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.
