So if you lurk in any AI subreddit, discord, forum, or issue tracker, its pretty obvious that the answer to "how do people trust these things when they make mistakes literally all the time and its impossible to know when" is that there is a general conspiracy theory that whenever the model does bad output it is the AI company nerfing their model on purpose: for anthropic, its that they are compute strapped. For openAI, getting sued or cucked. Google is that google just sort of fucks their own shit up all the time, same with Microsoft.
This kind of post basically dominates all of these forums. That systemic failures are one-off byproducts of the momentary malevolence of the companies. The gambler only complains about the house always winning when the house wins bigger than usual.
