By that logic, how can you trust OpenAI and Anthropic not to do the same?

For one, openai and anthropic are the top two AI labs and therefore have some reputation at stake. Openrouter is like aliexpress. Any fly-by night vendor can get listed on there.

The Chinese providers also have reputations at stake

Not all reputations are equal.

Good point, the American labs have an awful reputation, and public sentiment is so low it might as well be negative. Plus they've already broken our trust by scraping and stealing everyone's intellectual property to begin with, so they have a lot of catching up to do in terms of reputation and trust.

>Good point, the American labs have an awful reputation ...

Reddit/bluesky users seething at anthropic/openai doesn't matter, because they're not the one making the purchasing decisions for AI. Moreover all the complaints you mentioned applies to chinese AI labs as well, with the extra issue that they're beholden to the CCP. Taking the side of chinese ai labs because they're the competitors of american labs is "enemy of my enemy is my friend" logic, which is just dumb. It's like those people who think the US is bad, so then go and simp for china/russia.

Do you really trust the notorious liar Sam Altman?
