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

OpenAI has launched GPT-6.1 Sol, a new model that reportedly offers intelligence levels nearly matching GPT-6 Astra, but at one-fifth the cost for input and output tokens. Unveiled at OpenAI’s DevDay, GPT-6.1 Sol demonstrates improved factual accuracy, especially with difficult prompts, reducing factual errors from 11.4% to 7.7% at low reasoning effort. Across all reasoning settings, its error rate remains within 1.9% of GPT-6 Astra, making it a cost-effective alternative for agentic coding, computer use, and professional work.
