@atoponce That's funny given that ChatGPT 4o may be linked internally to some math engine.

At least that's my hypothesis. v3 (3.5?) failed miserably (as expected!) when I asked it to compute the inflection points of some curve (explanations correct, computations hallucinated), but ChatGPT+ using the Wolfram Plugin did it just fine.

v4o solved that same exercise perfectly without any (apparent) plugins.

Maybe this "problem" was too easy and it didn't make it to the math engine? (If it has one)
