AI API Cost per 1K Tokens
Standardize AI pricing! Most providers quote per million tokens, but many developers still think in thousands. Use this tool to see the real cost.
What is the "Cost per 1K Tokens" metric?
It is the standard unit of measurement for AI API pricing. It tells you how much it costs to process 1,000 tokens (roughly 750 words). Most providers now use "Cost per 1M tokens" due to declining prices, but 1K remains a common comparison point.
Why are input and output prices different?
Input tokens (your prompt) are cheaper because they are processed in parallel. Output tokens (the response) are more expensive because they must be generated one-by-one, requiring more compute time.
Which AI model has the lowest cost per 1K tokens?
Models like GPT-4o-mini and Claude 3 Haiku currently offer some of the lowest costs, often around $0.00015 per 1K input tokens.
How do I compare API pricing across providers?
Use our calculator to normalize pricing from different providers (OpenAI, Anthropic, Google) into a single "Cost per 1K tokens" or "Cost per 1M tokens" view.
