How AI API pricing works
Most AI APIs charge based on token usage. A token is roughly 4 characters or 0.75 words in English. You pay separately for input tokens (your prompt) and output tokens (the AI's response). Prices vary significantly between providers and models, our calculator helps you estimate real costs based on your expected usage volume.
Tips for reducing AI API costs
- Use prompt caching, Both OpenAI and Anthropic offer caching for repeated prefixes
- Right-size your model, Use smaller models (GPT-4o-mini, Claude Haiku) for simpler tasks
- Batch processing, Many providers offer 50% discounts for non-real-time batch requests
- Optimize prompts, Shorter, more efficient prompts reduce input token costs. Try our Prompt Generator
