LF LFM2 24B-A2B: RAM and VRAM requirements
LFM2 24B-A2B needs about 15.4 GB to run at Q4_K_M (the Q4_K_M GGUF file is ~13.43 GB to download; KV cache and overhead add the rest), or about 25.6 GB at Q8_0. The lightest hardware that runs it is Apple M4 (24GB).
LFM family · 24B params (Mixture-of-Experts: activates only 2.3B of 24B params per token, so generation is faster than the total size suggests) · released Feb 2026.

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 24B-A2B runs on 15 of 40 tracked devices at Q4_K_M.
Memory breakdown
How context length changes it
Longer context grows the KV cache, which for LFM2 24B-A2B is sized by its 2.3B active params, not the full 24B. It needs ~15.4 GB at 4k and ~51.8 GB at 128k.
Quantization sizes
| Quantization | Size on disk |
|---|---|

FAQ
How much VRAM or RAM does LFM2 24B-A2B need?
At Q4_K_M, LFM2 24B-A2B needs about 15.4 GB (weights ~13.43 GB + KV cache + overhead) at a 4k context. At Q8_0 budget ~25.6 GB.
What is the Q4_K_M GGUF file size of LFM2 24B-A2B?
The Q4_K_M GGUF file is about 13.43 GB to download, and the Q8_0 GGUF is about 23.61 GB. That is the weights file on disk; to run it you also need room for the KV cache and overhead, so budget ~15.4 GB of memory at Q4_K_M.
Can LFM2 24B-A2B run on a laptop?
LFM2 24B-A2B is large; you need a 24 GB+ GPU or a 32-48 GB Mac at Q4_K_M.
Is LFM2 24B-A2B cheaper to run because it is a MoE model?
It is faster, not lighter. LFM2 24B-A2B activates only 2.3B of 24B params per token (so it runs quickly), but all experts must stay in memory, so it still needs memory for the full 24B.
Can I use LFM2 24B-A2B commercially?
Conditionally. LFM Open License: free under $10M revenue; larger companies need a commercial license.
Understand the numbers
