LFM2.5 1.2B

16 tokens a second on Linux · no GPU · 4 CPUs · 31 GB RAM. No hosted API sells it, so this network is the place to run it.

1 build of LFM2.5 1.2B, 1 signed run on real machines: different packagers, precisions and engines, each a different file with its own numbers.

What it fits on

The smallest build needs about 1.0 GB; 17 of 18 kinds of machine on the network can hold it. Bars: each kind's memory (its card's, else RAM) · ticks: every build, at the size it held plus a fifth for the prompt.

How far back it remembers, machine by machine

Filled: the needle came back at that prompt size · outlined: asked and lost · blank: not asked · trained for 125K. 0 walks ended because the model forgot, 1 because the machine could not hold the prompt.

Carbon is location-based: signed energy × the yearly average of the grid where the machine signed its place (world grid average (place not signed); Ember Global Electricity Review 2025 (2024 generation), location-based). Facility overhead is not included. A machine on its own solar is not credited until it can prove it.
