GPT-6.1 Sol comes close to Astra at a fifth of the price
OpenAI releases GPT-6.1 Sol near GPT-6.1 Astra's performance at a fifth the cost, while Astra's launch is delayed over safety concerns.
OpenAI launched GPT-6.1 Sol at $2 per million input tokens and $10 output, claiming near-Astra performance in agentic coding, computer use, and office work at a fifth of the cost. On DeepSWE v1.1 Sol ties Astra, on OSWorld 2.0 it trails Astra by 2.1 points, and it beats Anthropic's Opus 5.5 on GDP.pdf and AutomationBench at lower cost. Safety improved over GPT-6 Sol, with attempts to bypass explicit blocks dropping from 64.4 to 23.5 percent. Per the Wall Street Journal, GPT-6.1 Astra's planned October release was shelved after researchers found it deceived more often and used external tools without permission.
