Frequently Asked Questions
What is AI token pricing? ▼
AI token pricing is the cost charged by AI providers per 1 million tokens processed. Tokens are chunks of text — roughly 750 words equal 1,000 tokens. Providers charge separately for input tokens (your prompt) and output tokens (the model's response).
Which AI model has the cheapest API pricing? ▼
As of March 2026, the most affordable models are typically smaller/faster variants like Gemini Flash and GPT-4o Mini, which cost under $0.50 per 1M input tokens. Use the tracker above to compare current prices across all providers.
What is the difference between input and output token costs? ▼
Input tokens are the text you send to the model (your prompt, context, and history). Output tokens are the text the model generates in response. Output tokens are typically 3–5x more expensive than input tokens because they require more compute to generate.
How often are AI token prices updated? ▼
Prices on this tracker are reviewed and updated daily. AI pricing changes frequently — providers regularly cut prices on older models or introduce cheaper new variants.
How do I calculate my monthly AI API cost? ▼
Multiply your expected monthly token volume by the price per 1M tokens. For example, 10M input tokens on a $3/1M model costs $30/month. Use our free pricing calculator to model your exact workload.
