Can I run LFM2 24B-A2B on Nvidia GeForce RTX 4090 (24GB)?
Yes. LFM2 24B-A2B runs on Nvidia GeForce RTX 4090 (24GB) at Q4_K_M (~15.4 GB of ~23 GB usable).
Runs at Q4_K_M using ~15.4 GB of ~23 GB usable.
That figure is at a 4k context and moves about ±15% as context length changes. Nvidia GeForce RTX 4090 (24GB) leaves ~7.6 GB of headroom.

FAQ
Can Nvidia GeForce RTX 4090 (24GB) run LFM2 24B-A2B?
Yes. LFM2 24B-A2B runs on Nvidia GeForce RTX 4090 (24GB) at Q4_K_M (~15.4 GB of ~23 GB usable).
How much memory does LFM2 24B-A2B need?
Nvidia GeForce RTX 4090 (24GB) has room to spare. At Q4_K_M the weights are ~13.43 GB; with KV cache and runtime overhead, budget ~15.4 GB at a 4k context. It is a Mixture-of-Experts model (24B total / 2.3B active), so all experts must stay in memory; memory tracks total params, not active params.
What is the best tool to run LFM2 24B-A2B 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.
