This is a copied space from LLM Trustworthy Leaderboard. Instead of displaying
the results as table this space was modified to simply provides a gradio API interface. 
Using the following python script below, users can access the full leaderboard data easily.
Python on how to access the data:
```python
# Import dependencies
from gradio_client import Client
# Initialize the Gradio client with the API URL
client = Client("https://rodrigomasini-data-only-llm-perf-leaderboard.hf.space/")
try:
    # Perform the API call
    response = client.predict("","", api_name='/predict')
    # Check if response it's directly accessible
    if len(response) > 0:
        print("Response received!")
        headers = response.get('headers', [])
        data = response.get('data', [])
        print(headers)
        # Remove commenst if you want to download the dataset and save in csv format
        # Specify the path to your CSV file
        #csv_file_path = 'llm-perf-benchmark.csv'
        # Open the CSV file for writing
        #with open(csv_file_path, mode='w', newline='', encoding='utf-8') as file:
        #    writer = csv.writer(file)
            # Write the headers
        #    writer.writerow(headers)
            # Write the data
        #    for row in data:
        #        writer.writerow(row)
        #print(f"Results saved to {csv_file_path}")
    # If the above line prints a string that looks like JSON, you can parse it with json.loads(response)
    # Otherwise, you might need to adjust based on the actual structure of `response`
except Exception as e:
