When you consider a house, do you just want to be a pay-to-stay tenant like in a hotel, or buy it but without blueprint and document, or own the house alone with all its wiring, plumbing, design and construction details? What if this house is AI ? Today’s release marks the first panoramic debut of IFM’s K2 fleet — six 360-open source LLMs ranging from 0.9B all the way to 375B covering deployment needs from smart watch to enterprise data center, all reaching SOTA or top tier performance, some punching above their weights. For every model, their training lifecycle, code, data, logs, all you need to reproduce the results and take it further are put in your hands. We are committed to transparent AI and open science.
