Interestingly the founder of TabNine (which was acquired by Codota[0]) is currently working at Open AI (edit: comments corrected me he left in December 2020 according to his blog). I imagine they're livid about Open AI creating a competing product.

TabNine at times was magical, but I stopped using it after Codota started injecting ads directly into my editor[1]

No Citadel can't just 'choose to front run' some RH trades. They are obligated to always execute at NBBO

They don't need to frontrun they'll clean up just from providing liquidity with the huge volatility in the symbol.

Citadel is split into Citadel Securities (the market making org which pays for orderflow) and the Citadel the hedge fund. The two halves of the business can't coordinate/share position info (or order flow info like others have implied). If they did they'd get absolutely demolished by the SEC. There is really no reason for them to do that though since they're already printing money from MMing.
