Rumor: GPT-6.1 Sol was originally planned as Astra Minor
A leak claims the model was first planned as Astra Minor, a considerably more powerful model than Sol, but pressure from Opus 5.5 and Sonnet 5.5 led OpenAI to repurpose it as the Sol model.

Seems like GPT-6.1 Sol was originally planned to be released as "Astra Minor", a considerably more powerful model than Sol. But then Opus 5.5 (and Sonnet 5.5) happened, and OpenAI decided they needed something stronger for the Sol model, so they repurposed it. GPT-6.1 is on another level compared to GPT-6 Sol.
