@haider1 leaked information about OpenAI's upcoming GPT-5.6 model lineup. Reportedly, Luna's performance will rival Codex 5.3 / GPT-5.4 but at a fraction of the cost, positioning it as the default model for about 80% of tasks. Terra will handle more complex workloads, while Sol Ultra is designed for the remaining roughly 5% of top-tier challenges that other models cannot solve. This information remains an unconfirmed rumor or leak.
