About TokenCalc.org
Who We Are
TokenCalc.org is dedicated to providing developers, AI engineers, and enterprises with the most precise, intuitive, and modern Multimodal AI Token Calculator and Cost Estimator.
In the current era of frontier large language models (such as GPT-5.5, Claude 3.7, Gemini 3.5, and DeepSeek V4-Pro), API calling structures and Token counting rules have become incredibly complex. Different text tokenizers, tile-based image segmentation, and unique video/audio duration metrics make cost estimation a black box. Moreover, multi-turn agent workflows face dynamic pricing due to context caching.
We created TokenCalc.org to demystify API pricing and help you calculate real-world model invocation costs in one single place.
Our Mission
Our mission is to make AI API billing completely transparent and predictable. We help developers find the most cost-effective and optimal model architectures while leveraging unified API gateways like Kie.ai to save up to 30%-60% on overall API expenses.
What We Do
We specialize in real-time estimation across these core modules:
- Real-time word and character counting combined with cross-comparison of text tokenizer counts across OpenAI o200k_base, cl100k_base, DeepSeek, Gemini, and Claude.
- Image token calculation based on high/low resolution tile-based segmentation, as well as native estimations for video and audio inputs.
- Custom multi-step AI Agent workflow simulation, tracking context accumulation and context caching hit rates to estimate the exact price of a full run.
- Interactive charts that display cost comparison side-by-side between official pricing and Kie.ai aggregate discounts.
Our Values
π― Precision
We match our calculation algorithms closely with official documentation from providers to minimize discrepancy.
π Continuous Updates
As providers drop prices, release new models, or introduce new tokenizers, we update our rates and configurations rapidly.
π€ Transparency
By visualising the underlying math of AI bills, we empower teams to make rational decisions regarding model selection.
