The Ultimate LLM API Cost Calculator
Scaling Enterprise AI applications requires strict budget control. The LLM API Cost Estimator is a specialized tool designed for developers, founders, and data scientists to accurately predict expenses across major language models like GPT-4o, Claude 3.5 Sonnet, and Google Gemini.
How does our Token Pricing Estimator work?
Unlike generic calculators that use simple word counts, our tool utilizes an in-browser Byte-Pair Encoding (BPE) tokenizer (specifically the cl100k_base encoding). This ensures that your input text is tokenized exactly how the AI provider processes it, giving you highly accurate input costs down to the fraction of a cent.
100% Client-Side & Private
Data privacy is critical when dealing with proprietary enterprise prompts. We do not send your text to any external servers. The entire tokenization process and cost calculation happen securely and locally within your browser's memory.
Frequently Asked Questions (FAQ)
- What is a token? A token is a raw unit of text. In English, 1 token is roughly equivalent to 0.75 words.
- Why are Input and Output prices different? Providers typically charge significantly more for output (generated) tokens because generating text requires more computational power than simply reading (processing) input prompts.
- What is "Bulk API Calls"? If you are processing a database (e.g., summarizing 5,000 product descriptions), you can set the bulk multiplier to instantly see the total batch cost.
