Omit previous chat message


I want to omit the previous entry in my current chatgpt rapport/session.

I’ve read through a few headings in the knowledge base.

I don’t want my query considered at all.

Is this what the thumbs up/down is for?

Will it strike it from my record?

Should I be using playground instead?

Lastly, does chatgpt “infer” from the sum and total of all of previous chat messages/sessions?

I thought I caught a whiff of something I mentioned days ago but in another chat at chatgpt/

It could be hallucinating or I could be needing a break from AI.
