Frequently Asked Questions about AI Token Costs
How accurate are these AI cost estimates?
We use official pricing from OpenAI, Anthropic, and Google's published API documentation as of March 2026. Prices are updated monthly. Actual costs may vary due to caching, batch discounts, or special promotions.
What are tokens in AI models?
Tokens are chunks of text (roughly 4 characters or 0.75 words). For example, "Hello, world!" is about 3-4 tokens. API providers charge per 1M tokens. Use our sliders to simulate your exact prompt lengths.
Which AI model is cheapest for high volume?
GPT-5 nano ($0.025/1M input) is currently the most affordable, followed by Gemini 3.1 Flash-Lite ($0.25/1M input). For balanced performance, GPT-4o mini ($0.15/1M input) is popular.
How do GPT-4o and Claude 4.6 pricing compare?
GPT-4o costs $2.50/1M input and $10.00/1M output. Claude 4.6 Sonnet costs $3.00/1M input and $15.00/1M output. Claude is stronger at reasoning tasks, while GPT-4o offers faster response times.
Can I calculate batch processing costs?
Yes! Adjust the "Requests per User per Day" slider to simulate batch workloads. For OpenAI batch API, costs are typically 50% lower - we're adding this feature soon.
How often do AI API prices change?
Major providers update prices 2-3 times per year. We update our calculator within 48 hours of any official pricing announcement. Last update: March 15, 2026.
