No, the ChatGPT API is not free. The usage of the API is a paid service provided by OpenAI. You would need to refer to OpenAI’s pricing and documentation for details on the cost and terms of using the ChatGPT API.

As of my knowledge cutoff in the chat gpt specific pricing details for the ChatGPT API had not been disclosed by OpenAI. To obtain the most accurate and up-to-date information regarding pricing, I recommend visiting the OpenAI Pricing page r contacting OpenAI directly for the latest details on API costs.

As an AI language model, I don’t have access to real-time information about pricing or the specifics of OpenAI’s API offerings. However, as of my last knowledge update in September 2021, OpenAI’s GPT-3.5 models, including ChatGPT, were not available for free and were offered through the OpenAI API at a cost. Pricing and availability may have changed since then, so I recommend visiting the OpenAI website or contacting OpenAI directly for the most up-to-date information on their API pricing and offerings.
