Free AI Token Calculator & Price Comparison

A token is a unit of text that AI models process. It can be a word, part of a word, or even punctuation. Different models use different tokenization methods, which is why our calculator provides accurate counts for each specific model. For example, the word 'hello' is typically one token, while 'tokenization' might be split into multiple tokens.

Our cost calculations are based on official pricing from each provider and are updated daily. We use the exact same tokenizers that the providers use, ensuring 100% accuracy in token counting and cost estimation. Our data is synchronized with OpenAI, DeepSeek, Claude, and Gemini official pricing APIs.

Yes! Our token calculator is completely free to use with no limits. We believe in providing accessible tools to help developers and researchers make informed decisions about AI model usage. There are no hidden fees, registration requirements, or usage restrictions.

We support over 500+ AI models from major providers including OpenAI (GPT-4, GPT-3.5-turbo, GPT-4o), DeepSeek (V3 series), Anthropic Claude (3.5 Sonnet, 3 Haiku, 3 Opus), Google Gemini (1.5 Pro, 1.5 Flash), and many others. Our database is updated regularly with new model releases.

Simply paste your text into our calculator, and it will instantly show you the token count and cost estimation for all supported models. The calculator works in real-time, so you can see changes as you edit your text. You can also compare costs across different models to find the most cost-effective option.

Input pricing is the cost for tokens you send to the AI model (your prompt), while output pricing is the cost for tokens the model generates (its response). Most AI providers charge different rates for input and output tokens, with output tokens typically being more expensive due to the computational cost of generation.

We update our pricing data daily to ensure accuracy. AI model pricing can change frequently, especially for newer models, so we maintain real-time synchronization with provider APIs. If you notice any pricing discrepancies, please let us know and we'll investigate immediately.

Absolutely! Our token calculator is free for both personal and commercial use. Many developers, startups, and enterprises use our tool to estimate AI costs for their applications, chatbots, content generation systems, and other AI-powered products. There are no licensing restrictions.

Different AI models use different tokenization algorithms. OpenAI uses tiktoken, while other providers have their own methods. The same text might result in different token counts across models because they split words and handle special characters differently. This is why model-specific calculators are essential for accurate cost estimation.

You can reduce costs by: 1) Choosing more cost-effective models for simpler tasks, 2) Optimizing your prompts to be more concise, 3) Using our comparison tool to find the best price-to-performance ratio, 4) Considering input vs output token pricing when designing your application, and 5) Regularly monitoring usage with our calculator.
