Logit bias value is invalid or outside of the acceptable range.

To fix the 400 status error related to the logit_bias value, you need to ensure that the values provided are within the valid range. Here are the steps to correct this:

• Adjust the logit_bias values to be between -100 and 100.

• Replace the invalid value of -1000 with a valid value, such as -100 if you want to strongly discourage the generation of a particular token.

Key adjustments:

• Use a value between -100 and 100 for each token in the logit_bias parameter.

• For example, if you want to block a token, use -100, and for encouraging a token, use a positive value up to 100.
