i think this deserves more attention gpt-6 sol was released 7 days ago, and 6.1 sol is already 5 points higher on the intelligence index it's unlikely this was trained in 7 days, so my understanding is that Terra was meant to become Sol, while Astra Minor sat between sol and Astra at opus-level pricing -- but after opus 5.5 launched, and openai cut the price and shipped astra minor as 6.1 sol
