Claim
a complete inability to do advanced math before the o-series
Correction

This overstates earlier models’ weaknesses. Before the o-series, OpenAI had already reported models solving nontrivial competition-math problems, including AIME/IMO-style problems, and GPT-4o solving some AIME questions.

Full reasoning

Saying pre-o-series models had a "complete inability" to do advanced math is too strong and is contradicted by OpenAI's own published results.

  • In OpenAI’s September 12, 2024 writeup on o1, the company explicitly compared GPT-4o (which predates the o-series) on the 2024 AIME exams and reported that "GPT‑4o only solved on average 12% (1.8/15) of problems." That is much worse than o1, but it is not a complete inability to do advanced math.
  • Earlier still, OpenAI’s February 2, 2022 post "Solving (some) formal math olympiad problems" reported a language-model-based theorem prover that solved challenging high-school olympiad problems, including AIME problems and two problems adapted from the IMO.

So the broad point that math capability improved a lot may be fair, but the specific claim that models had a complete inability before the o-series is factually incorrect.
