About LFM2 1.2B

What is LFM2 1.2B?

LFM2 1.2B is a 4-bit quantized MLX build of Liquid AI’s model, packaged to run directly on Apple silicon instead of a remote server.

What it is good at on iPhone

  • Quick everyday questions

  • Fast tool use, like adding a reminder

Trade-off: bigger models give more depth on hard reasoning and long-form writing.
