Can I run LFM2 1.2B on 32GB RAM Laptop (CPU/iGPU only)?
Yes. LFM2 1.2B runs on 32GB RAM Laptop (CPU/iGPU only) at Q4_K_M (~2.5 GB of ~28 GB usable).
Runs at Q4_K_M using ~2.5 GB of ~28 GB usable. You have room for FP16 for higher quality.
That figure is at a 4k context and moves about ±15% as context length changes. 32GB RAM Laptop (CPU/iGPU only) leaves ~25.5 GB of headroom, room to step up to FP16 for higher quality.

Running cost · estimate
- Power draw
- ~28 W
- Electricity / 1M tokens
- ~$0.04
- Pays for itself after
- ~2,391M tok
At ~$0.15/kWh and the estimated ~32 tok/s, a million generated tokens costs about $0.04 in electricity. Versus a hosted API at ~$0.5 per million tokens, the ~$1,100 32GB RAM Laptop (CPU/iGPU only) pays for itself after roughly 2,391 million tokens, so local hardware is mostly a fixed cost, not a per-token one. TDP is the peak draw, so this is an upper bound. Assumptions.

FAQ
Can 32GB RAM Laptop (CPU/iGPU only) run LFM2 1.2B?
Yes. LFM2 1.2B runs on 32GB RAM Laptop (CPU/iGPU only) at Q4_K_M (~2.5 GB of ~28 GB usable).
How much memory does LFM2 1.2B need?
32GB RAM Laptop (CPU/iGPU only) has room to spare. At Q4_K_M the weights are ~1.42 GB; with KV cache and runtime overhead, budget ~2.5 GB at a 4k context.
What is the best tool to run LFM2 1.2B 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.
