Building a Simple AI-Powered App with Streamlit and Hugging Face

Let’s build a text summarization app using a free model from Hugging Face.

Step 1: Import Required Libraries

import streamlit as st
from transformers import pipeline
model_name = "sshleifer/distilbart-cnn-12-6"
revision = "a4f8f3e"
# Load Hugging Face summarization model
summarizer = pipeline("summarization", model=model_name, revision=revision)

Step 2: Create a Simple UI

Streamlit makes it easy to add UI elements like text inputs, buttons, and sliders.

st.title("AI-Powered Text Summarizer")
st.write("Enter text below and get a concise summary powered by AI.")
user_input = st.text_area("Enter your text:")

Step 3: Use the Hugging Face Model to Generate a Summary

if st.button("Summarize"):
    if user_input:
        summary = summarizer(user_input, max_length=100, min_length=30, do_sample=False)
        st.subheader("Summary:")
        st.write(summary[0]["summary_text"])
    else:
        st.warning("Please enter text to summarize.")

Step 4: Run the App

Save the script as app.py and run the following command:

streamlit run app.py

This will launch a web app where users can enter text and receive AI-generated summaries.

Deploying the Streamlit App

Once your app is ready, you can deploy it on Streamlit Cloud or Hugging Face Spaces.

Deploying on Hugging Face Spaces:

1. Create an account on Hugging Face.

2. Go to Spaces and create a new space.

3. Select Streamlit as the app type.

4. Push your app’s files to the repository.

5. Your app will be hosted for free on Hugging Face!
