X Will Deploy AI to Write Community Notes, Expand Fact-Checking

So, the "two" of the one-two punch to completely ruin the ability to effectively fact-check is in motion, then.

Their AI is trained on X-content I assume.

Well, it's being re-trained because Musk doesn't like the answers it gives:

So long story short, community notes will be useless.

"We will use Grok 3.5 (maybe we should call it 4), which has advanced reasoning, to rewrite the entire corpus of human knowledge, adding missing information and deleting errors," Musk wrote on X on Friday night.

Then, he said he would retrain Grok's latest model on that new base of knowledge to be free of proverbial waste. "Far too much garbage in any foundation model trained on uncorrected data," he added.

Yeah, that'll go well.
