OpenAI launches GPT-6.1 Sol, says it nearly matches GPT-6 Astra and costs less

OpenAI has launched GPT-6.1 Sol, a new AI model that reportedly achieves nearly the same intelligence as GPT-6 Astra but at one-fifth the cost. This model offers significant improvements over its predecessor, GPT-6 Sol, across complex professional tasks like coding, document understanding, and multistep workflows, while also enhancing factual accuracy and reliability. GPT-6.1 Sol is available to various ChatGPT users, excluding the standard Chat interface, and its release follows the scrapping of GPT-6.1 Astra due to safety concerns.
