emmanuelvivier · x · 2026-09-23
Weeks after shipping GPT-6 Astra, OpenAI expanded the GPT-6 family with updated Sol and Luna models, claiming half the price of the previous generation and fewer errors on coding and computer-use tasks.
- Positioning: Sol targets complex work like coding; Luna is built for high-volume clerical tasks with clear goals — summarizing documents, extracting information, quick answers.
- OpenAI: "GPT-6 Astra introduced a new generation of intelligence; these models extend its benefits by making that intelligence more efficient and accessible."
- The original Sol and Luna tiers debuted earlier this year.
