The lab, founded by Abu Dhabi&rsquo;s MBZUAI university, calls it the industry&rsquo;s largest fully open-source model fleet.<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Six sizes from smartwatch to data centre<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The fleet spans models of 0.9, 3.7, 7, 32, 36 and 375 billion parameters. IFM aims the smallest variants at heavily constrained devices such as smartwatches and smart glasses, as well as smartphones. The dense 32B model and the sparse 36B-A4B model suit local servers, while the flagship K2-Horizon-375B-A23B is a Mixture-of-Experts that activates just 23 billion parameters per token. It offers a 512K-token context window.<\/p><div id=\"netgu-941874607\" class=\"netgu-content netgu-entity-placement\"><aside class=\"deals-top deals-top--compact\">\n\n\t\t\t<h3

Notably, IFM revised its own Terminal-Bench score downward after flagging 24 test runs as faulty &ndash; an unusually transparent move in a field that rarely spares optimistic self-reporting.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Sources:<\/em> <a href=\"https:\/\/ifm.ai\/blog\/k2\/\">IFM blog<\/a> &middot;
