I signed up for the PRO plan, which was "useful" for my purposes to a certain extent. BUT some AIs are NOT the model indicated on the label. Just do a very simple test, ask the AI what version it is; the wrong version can disrupt people's work. Sonnet 4 was running 3.5. Grok 4 was running the initial Grok 1. I couldn't do any further checks. And Playground V2 doesn't work; it says "Application error: a client-side exception has occurred while loading playground.a4f.co (see the browser console for more information)." I prefer to believe it was an internal configuration error. Please fix this.
