Your AI and this story

  • GPT-6 AstraIn its training data
  • Claude Opus 5.5In its training data
  • Gemini 4 HydrogenIn its training data
  • Grok 4.7In its training data

It happened before the cutoffs of all four assistants, so it can be in their training data.

Key facts

  • 301 new validated planets
  • Explainable classifier mimicking the vetting steps of human experts

What happened

ExoMiner vetted thousands of Kepler signals and confidently validated hundreds as planets.

Why it matters

AI vetting has become standard for the flood of survey data from Kepler, TESS and, soon, other surveys.
