GPT-5.6 Pro still gets stuck on the Jacobian Conjecture

The post says this is already the fourth example of someone trying many manual approaches with GPT-5.6 Pro and still failing, suggesting the model’s competence is jagged rather than uniform.
In the quoted thread, the author says they ran six separate GPT-5.6 Pro instances, all without search, and none could disprove the Jacobian Conjecture. Even with hints and reminders to widen the search space, the model kept looking in an extremely narrow region of polynomial families and got stuck.
The takeaway is that for hard math problems, the model can easily miss the right search strategy, and the poster recommends combining multiple models instead of relying on one system alone.
