The post claims that GPT-5.6 and Fable 5 contributed to three mathematical breakthroughs in a single week:
- Fable 5 allegedly helped disprove the 87-year-old Jacobian Conjecture.
- GPT-5.6 Pro is said to have solved all 6 IMO 2026 problems on its first attempt with no human help.
- The same model is also claimed to have closed a 30-year gap in convex optimization, a problem open since 1996.
The attached Reddit screenshot repeats the same headline-style claims and frames them as major math milestones linked to recent model capabilities.
