The Mohamed bin Zayed University of Artificial Intelligence (MBZUAI), in partnership with technology group G42, announced on September 9, 2025, the release of K2 Think—a new open-source AI model specializing in complex logical reasoning. The key feature of K2 Think is "parameter efficiency": with only 32 billion parameters, the model demonstrates performance on par with flagship models that are 20 times larger. This is achieved through a combination of six innovative techniques, including deep supervised fine-tuning on "long chain-of-thought" data and the use of specialized hardware from Cerebras. The release of K2 Think is a significant step in the UAEs strategy to develop "sovereign AI"—its own advanced technologies that reduce dependence on foreign developments. The model is fully open: not only the weights are published, but also the training data and code, allowing researchers worldwide to reproduce and build upon it.
