-# Phi-4 Mini Instruct – Hugging Face Space
+# Phi-4 Reasoning Demo (Hugging Face Space)
 
-This Space is a lightweight Gradio demo using the `microsoft/Phi-4-mini-instruct` model from Hugging Face for compact, instruction-tuned language generation.
+This is a Gradio-powered demo using the `microsoft/phi-4-reasoning-plus` model from Hugging Face for advanced reasoning and text generation.
 
 ## 🔍 Model
 
-- **Model:** [`microsoft/Phi-4-mini-instruct`](https://huggingface.co/microsoft/Phi-4-mini-instruct)
-- **Type:** Small, instruction-tuned LLM
-- **Use Case:** Text generation for assistant-style tasks with low resource usage
+- **Model:** [`microsoft/phi-4-reasoning-plus`](https://huggingface.co/microsoft/phi-4-reasoning-plus)
+- **Use Case:** Text generation, reasoning tasks, assistant-style prompts
 
 ## 🚀 Features
 
-- Lightweight and fast, great for CPU-only Spaces
-- Simple Gradio interface for trying out prompts
-- Hugging Face `transformers` integration
+- Simple Gradio interface
+- Accepts a user prompt and returns a generated response using the Phi-4 model
