ArXiv Bans Accounts Flooding the Platform With AI-Generated Research Papers
ArXiv is banning accounts uploading AI-generated slop, but the real fight is over whether its endorsement system can be rebuilt to stop the flood.
A thread running hot on Reddit's r/artificial forum has landed on a sharp and expensive consensus: among users who rely on AI tools professionally, Perplexity wins for verifiable facts and ChatGPT wins for complex analysis — and most are now carrying both subscriptions.
The trust distinction comes down to auditability. Perplexity surfaces inline citations that let users trace every claim back to a source before acting on it. ChatGPT's reasoning is generally stronger, but its sourcing is thinner and harder to verify independently — a real liability when you are accountable for the output. Neither tool has bridged the other's gap.
The practical result is subscription costs of roughly $40 per month combined. That is a signal neither product has delivered the knockout that would consolidate the serious-use market. It is also a signal that both companies have found a stable equilibrium where the user's need to hedge funds both.
Perplexity and OpenAI are each growing their user bases without cannibalizing the other's core advantage. That is a comfortable position until someone actually closes the gap — and then it will not be comfortable for whoever is on the wrong side of it.
