The Cosmos-Reason2-2B model delivers state‑of‑the‑art reasoning capabilities in a compact 2‑billion parameter package. It leverages a hybrid training approach that combines symbolic reasoning with large‑scale neural data to achieve superior performance on logical inference tasks. Despite its small size, the model maintains a long contextual window, enabling it to process up to 8K tokens per input without significant loss in accuracy. The architecture incorporates efficient attention mechanisms that reduce computational overhead, making it ideal for deployment on edge devices and research experiments. Benchmarks show that Cosmos-Reason2-2B outperforms comparable models by a notable margin on reasoning‑focused datasets while consuming less power. Its open‑source release encourages community contributions, fostering rapid iteration and the development of new reasoning‑augmented applications.
