MBZUAI's Institute of Foundation Models and G42 launched K2 Think on 2025-09-09. The announcement described a 32-billion-parameter reasoning system and published materials covering weights, training data and deployment code. This article concerns that original release. [1]

## How the team described its approach

The launch combined supervised training on long reasoning examples with reinforcement learning using verifiable rewards. It also described planning and additional computation during inference. The team reported strong mathematics benchmark results; those comparisons belong to the models and evaluation conditions used at launch. [1]

## Evaluate a model for your workload

Keep a set of problems with answers you can check independently. Compare correctness, response time and the resources required to run the model. Include failures and ambiguous questions, rather than only examples where the output looks convincing.

Before deployment, read the exact release's model card, license and hardware requirements. A parameter count alone does not establish that a model fits your laptop or server.
