Ornn AI has unveiled the Ornn Token Price Index (OTPI), a new metric designed to measure the actual cost of tokens generated by AI models from developers like OpenAI and Anthropic. The OTPI provides a daily assessment of costs, expressed in "USD per million tokens," and is weighted by the volume of tokens traded for each model. This index aims to reflect the impact of various factors such as model usage patterns, input-to-output ratios, and caching on the actual costs of AI inference tokens.
