Calculate Pricing

from transformers import AutoTokenizer
from swarms_cloud import calculate_pricing

# Initialize the tokenizer
tokenizer = AutoTokenizer.from_pretrained("gpt2")

# Define the example texts
texts = ["This is the first example text.", "This is the second example text."]

# Calculate pricing and retrieve the results
total_tokens, total_sentences, total_words, total_characters, total_paragraphs, cost = calculate_pricing(texts, tokenizer)

# Print the total tokens processed
print(f"Total tokens processed: {total_tokens}")

# Print the total cost
print(f"Total cost: ${cost:.5f}")

Generate an API key
