What to know

  • OpenAI released three GPT-6 variants: Astra (flagship), Sol (mid-tier for business workflows), and Luna (budget for high-volume tasks).
  • Sol claims to outperform Claude Opus 5 at one-tenth the price, addressing affordability for developers running continuous applications.
  • The strategy mirrors automotive industry practices, allowing developers to select models matching specific task complexity and budgets.

“The Luna model is the one that handles the less glamorous, high-volume tasks: fast responses, simple automation, the type of tasks which do not require a genius but only speed and cost efficiency.”
