# LFM2-8B-A1B
> 8B parameter Mixture-of-Experts model with 1.5B active parameters (deprecated - use LFM2.5-8B-A1B instead)
export const TextLlamacpp = ({ggufRepo, samplingFlags}) =>
Install:
{`brew install llama.cpp`}
Run:
{`llama-cli -hf ${ggufRepo} -c 4096 --color -i \\

The -hf flag downloads the model directly from Hugging Face. For other installation methods and advanced usage, see the llama.cpp guide.

← Back to Text Models
This model is deprecated. Use [LFM2.5-8B-A1B](/lfm/models/lfm25-8b-a1b) for improved performance and a 128K context length.
LFM2-8B-A1B is Liquid AI's Mixture-of-Experts model, combining 8B total parameters with only 1.5B active parameters per forward pass. This delivers the quality of larger models with the speed and efficiency of smaller ones—ideal for on-device deployment.
