AI training data

The corpus used to bake parametric memory. Your brand in that pile is why ChatGPT “just knows” you — until it doesn’t.

Licensing and robots.txt change what gets in next time. You cannot surgically edit yesterday’s weights.

The date after which the model’s weights don’t include the web. Anything newer needs browsing or RAG.

Deals where labs pay (or get blocked) for using professional content. Changes which domains appear in answers.

Can I delete myself from training? +

Opt-outs affect future runs, not a time machine. Legal routes exist in some regions; they are slow.
