LF LFM2 700M: RAM and VRAM requirements

LFM2 700M needs about 1.9 GB to run at Q4_K_M (the Q4_K_M GGUF file is ~0.92 GB to download; KV cache and overhead add the rest), or about 1.7 GB at Q8_0. The lightest hardware that runs it is Apple M1 (8GB).

Q4_K_M and Q8_0 are GGUF download (file) sizes. Memory @ Q4 includes the KV cache and overhead, so it runs larger than the file on disk.

Will it run on your device?

LFM2 700M runs on 40 of 40 tracked devices at Q4_K_M.

How context length changes it

4k context ~1.9 GB 32k context ~3.4 GB 128k context ~8.3 GB

LFM2 700M is small enough that the context window is the thing to size for: 128k needs ~8.3 GB versus ~1.9 GB at 4k, so pick the window you actually use.

Speed drops too: every token re-reads the KV cache, so at 128k context LFM2 700M generates at roughly ~12% of its short-context speed. How this is estimated.

Lower quant = smaller and faster, slightly lower quality. Q4_K_M is the common default.

FAQ

How much VRAM or RAM does LFM2 700M need?

At Q4_K_M, LFM2 700M needs about 1.9 GB (weights ~0.92 GB + KV cache + overhead) at a 4k context. At Q8_0 budget ~1.7 GB.

What is the Q4_K_M GGUF file size of LFM2 700M?

The Q4_K_M GGUF file is about 0.92 GB to download, and the Q8_0 GGUF is about 0.74 GB. That is the weights file on disk; to run it you also need room for the KV cache and overhead, so budget ~1.9 GB of memory at Q4_K_M.

Can LFM2 700M run on a laptop?

Yes, LFM2 700M fits on a 16 GB machine at Q4_K_M and runs on Apple Silicon or a 12 GB+ GPU comfortably.

Can I use LFM2 700M commercially?

Conditionally. LFM Open License: free under $10M revenue; larger companies need a commercial license.
