Frequently Asked Questions
What AI tools are available?
We offer free AI tools including LLM API cost calculators, token counters, model comparison tools, and pricing calculators for popular AI services like OpenAI, Claude, Gemini, and DeepSeek.
How accurate are the AI pricing calculators?
Our calculators use the latest official pricing from AI providers as of January 2025. Prices can change, so we recommend checking official documentation for the most current rates. We update our tools regularly to reflect pricing changes.
What is a token in AI models?
A token is a unit of text that AI models process. Roughly, 1 token equals about 4 characters or 0.75 words in English. Different models tokenize text differently, but this approximation works for cost estimation.
Which AI model is the cheapest?
As of January 2025, Google Gemini 2.0 Flash offers extremely competitive pricing at $0.10 per million input tokens. DeepSeek R1 is also very affordable at $0.55 input / $2.19 output per million tokens. GPT-4o-mini from OpenAI is another budget-friendly option.
How do I choose the right AI model for my project?
Consider your requirements: for complex reasoning tasks, models like Claude Opus or GPT-o1 excel. For general tasks, GPT-4o or Claude Sonnet offer great balance. For high-volume, cost-sensitive applications, consider Gemini Flash, DeepSeek R1, or mini variants.
