Glad I'm not the only one. Almost every factual thing with new opus is wrong (and it now even happens with 4.6?). I asked it about car stuff yesterday and it totally misrepresented how a car axle even looks like fundamentally. Today I talked about my CV and it was just plain wrong. I don't know what happened, it wasn't like this a few weeks back and I'm even considering cancelling claude alltogether. GPT 5.5 for coding is fine and way more stable, but regular work is just broken.
