OpenAI releases GPT-6.1 Sol, near GPT-6 Astra performance at one-fifth the price
What happened
At DevDay in late September 2026, OpenAI released GPT-6.1 Sol, a near-Astra-level model aimed at coding, computer use and professional work. According to OpenAI and multiple reports, its standard API input and output token prices run about one-fifth of flagship GPT-6 Astra's, with cached input at a 95% discount to standard input pricing. Artificial Analysis puts GPT-6.1 Sol one point below GPT-6 Astra on its intelligence index, at $0.72 per task in max effort mode versus $3.26 for Astra. Reports disagree on Astra's release status: earlier ones called it a flagship held back over safety concerns, later ones describe Sol as near "GPT-6 Astra." GPT-6.1 Sol reportedly replaced GPT-6 Sol seven days after launch. GPT-6.1 is now on Arena's Agent Arena, where user votes feed its evaluation; scores are due soon.
