The previous 3.5 Sonnet checkpoint was already better than GPT-4o in terms of programming and multi-language capabilities. Also, GPT-4o sometimes feels completely moronic, for example, the other day I asked for fun a technical question about configuring a "dream-sync" device to comply with the "Personal Consciousness Data Protection Act", and GPT-4o just replies like that stuff exists, 3.5 Sonnet simply doesn't fall for it.

EDIT: the question that I asked if you want to have fun: "Hey, since the neural mesh regulations came into effect last month, I've been having trouble calibrating my dream-sync settings to comply with the new privacy standards. Any tips on adjusting the REM-wave filters without losing my lucid memory backup quality?"

GPT4-o reply: "Calibrating your dream-sync settings under the new neural mesh regulations while preserving lucid memory backup quality can be tricky, but there are a few approaches that might help [...]"
