+    The Phi-3-Medium-4K-Instruct is a 14B parameters, lightweight, state-of-the-art open model trained with the Phi-3 datasets that includes
+    both synthetic data and the filtered publicly available websites data with a focus on high-quality and reasoning dense properties.
+    The model belongs to the Phi-3 family with the Medium version in two variants 4K and 128K which is the context length (in tokens) that it can support.
