Helemento

Helemento is an online OpenAI pricing calculator for estimating the cost of generating text with GPT models. With a few clicks, you can enter how many words you plan to generate, choose the base model, and instantly view an estimated price.

To use it, select a word amount (from 1k up to 1m) and then pick a model such as ChatGPT, Curie, Babbage, Davinci, GPT-4 8K, GPT-4 32K, or Ada. Each option includes a displayed per‑1k‑tokens rate, so you can compare costs across models before committing.

The calculator is designed for quick planning—especially useful when you’re estimating larger content volumes like 100k, 500k, or up to 1 million words. After you hit Calculate, the estimated price appears right away, helping you budget for different model choices.

Model rates shown include: ChatGPT ($0.002/1k tokens), Curie ($0.002/1k tokens), Babbage ($0.005/1k tokens), Davinci ($0.02/1k tokens), GPT-4 8K ($0.06/1k tokens), GPT-4 32K ($0.12/1k tokens), and Ada ($0.0004/1k tokens).

What does Helemento calculate?

It estimates the cost of generating a given amount of text with OpenAI GPT models based on the selected word count and model pricing.

How do I get an estimate on Helemento?

Enter the number of words (e.g., 10k or 1m), select a base language model, then click Calculate to see the estimated price.

Which models can I estimate with?

You can choose from ChatGPT, Curie, Babbage, Davinci, GPT-4 8K, GPT-4 32K, and Ada—each with a shown per‑1k‑tokens rate.

Can I estimate costs for large text volumes like 1 million words?

Yes. The word count selector includes up to 1m, so you can estimate large-scale generation in one run.

What are the pricing rates shown for each model?

Helemento lists per 1k tokens for each model: ChatGPT ($0.002), Curie ($0.002), Babbage ($0.005), Davinci ($0.02), GPT-4 8K ($0.06), GPT-4 32K ($0.12), and Ada ($0.0004).
