To open source or not

We have built an internal postman type of tool which reads your code through VS code plugin, and automatically fills up all the required fields for the api call and generates different test cases.

We use GPT-4 to do all this, its not replacement to testing but it helps with 80% of our api test cases.

We are planning to open source it but not sure if this will be useful to others. Do you think we should open source this, is it useful to other people or else we will not put in effort to decouple it.
