Input value is less than the required minimum limit. Please ensure 'max_tokens' is set to a value of at least 1.

The 400 status error in the OpenAI API, specifically the error message indicating that 'max_tokens' is less than the minimum of 1, is occurring because the max_tokens parameter in your API request is not meeting the minimum requirement.

Here are the key points:

• The max_tokens parameter must be at least 1, as it specifies the minimum number of tokens the model should generate in the completion.

• Setting max_tokens to a value less than 1 is invalid and results in a "Bad Request" error, which is represented by the 400 status code.

This error indicates that the API request was not properly configured, specifically that the max_tokens value is invalid.
