Gemini 4 Argon extends solutions to 59-year-old fusion magnetic field problem

Researchers used Gemini 4 Argon in Google's Antigravity environment to remove a symmetry restriction from Matt Landreman's exact magnetic field solutions. The new configurations give extra reference cases for verifying plasma equilibrium code, but do not solve fusion energy.

• Gemini agents produced promising candidates within hours
• The problem traces to Harold Grad's 1967 conjecture
• OpenAI's GPT-6 Astra Pro earlier helped find counterexamples
• Result is mathematical reference cases, not an energy breakthrough
