2 min with Fused

Quick ways to get started with Fused in Workbench.

Open a simple dataset​

@fused.udf
def udf(path = "s3://fused-sample/demo_data/housing/housing_2024.csv"):
    import pandas as pd
    housing = pd.read_csv(path)

Convert data quickly​

@fused.udf
def udf():
    import pandas as pd
    df = pd.read_excel("s3://fused-sample/demo_data/housing_2024.xlsx")
    df.to_parquet("s3://fused-sample/demo_data/housing_2024.parquet")
    
    return df

Turn any data into an API​

Turn any code into an API (similar to our Quickstart):

@fused.udf
def udf(path: str = "s3://fused-sample/demo_data/housing/housing_2024.csv"):
    import pandas as pd
    housing = pd.read_csv(path)
    housing['price_per_area'] = round(housing['price'] / housing['area'], 2)
    
    return housing[['price', 'price_per_area']]

Tips & Tricks​

  • Change the model! We provide models from all major vendors:
    • Kimi K2 -> Best well balanced model. Fast & Very Good
    • GPT 4.1 -> Advanced coding, higher context
    • Claude Opus 4 -> Slower, but great for complex coding
  • Try out the suggestions! Our models auto suggest what you could do next based on all your code
  • Ask crazy things you don’t know how to do!
  • Come back tomorrow, we'll most certainly have some new stuff! 🧑‍💻

Share your experience​

  • Tag udf_ai on Twitter, we’ll repost you!
  • Share which prompts have worked with us!

Data First IDE: Table / Map view​

Workbench is built for data teams.

Toggle between Map/Table view based on your data!

Return HTML code & make a chart!​

You can return HTML code directly in Fused and turn your data into an embedded Chart:

@fused.udf
def udf(path = "s3://fused-sample/demo_data/housing/housing_2024.csv"):
    from fastapi import Response
    import pandas as pd
    import altair as alt
    
    housing = pd.read_csv(path)
    housing['price_per_area'] = round(housing['price'] / housing['area'], 2)
    
    chart_html = alt.Chart(housing).mark_point().encode(
        x='price',
        y='price_per_area'
    ).to_html()

    
    return Response(chart_html.encode('utf-8'), media_type="text/html")

Go to the "Embed" tab to see your chart:
