+## Overview
+
+**Microsoft Research** developed and released the **Phi-4-reasoning** series, a cutting-edge family of reasoning-focused language models optimized for chain-of-thought (CoT), step-by-step problem solving, and high-efficiency inference. These models excel in advanced mathematical reasoning, scientific Q&A, and instruction-following scenarios.
+
+The Phi-4 models introduce extended context lengths, ChatML reasoning templates, and strong performance on benchmark datasets, while maintaining compact sizes that are ideal for memory- and latency-constrained environments.

+## Use it with Jan (UI)
+
+1. Install **Jan** using [Quickstart](https://jan.ai/docs/quickstart)
+2. Use in Jan model Hub:
+   ```bash
+   cortexso/phi4
+   ```
+
+## Use it with Cortex (CLI)
+
+1. Install **Cortex** using [Quickstart](https://cortex.jan.ai/docs/quickstart)
+2. Run the model with command:
+   ```bash
+   cortex run phi4
+   ```
