Can I run LFM2.5 8B-A1B on Nvidia GeForce RTX 4080 (16GB)?
Yes. LFM2.5 8B-A1B runs on Nvidia GeForce RTX 4080 (16GB) at Q4_K_M (~6.7 GB of ~15 GB usable).
Runs at Q4_K_M using ~6.7 GB of ~15 GB usable. You have room for Q8_0 for higher quality.
That figure is at a 4k context and moves about ±15% as context length changes. Nvidia GeForce RTX 4080 (16GB) leaves ~8.3 GB of headroom, room to step up to Q8_0 for higher quality.

FAQ
Can Nvidia GeForce RTX 4080 (16GB) run LFM2.5 8B-A1B?
Yes. LFM2.5 8B-A1B runs on Nvidia GeForce RTX 4080 (16GB) at Q4_K_M (~6.7 GB of ~15 GB usable).
How much memory does LFM2.5 8B-A1B need?
Nvidia GeForce RTX 4080 (16GB) has room to spare. At Q4_K_M the weights are ~5.2 GB; with KV cache and runtime overhead, budget ~6.7 GB at a 4k context. It is a Mixture-of-Experts model (8.3B total / 1.5B active), so all experts must stay in memory; memory tracks total params, not active params.
What is the best tool to run LFM2.5 8B-A1B 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.
