OpenAI introduced GPT-6.1 Sol as an upgrade to GPT-6 Sol, 9to5Mac reported during the company's DevDay event. OpenAI says the model nearly matches GPT-6 Astra on agentic coding, computer use and professional work while charging one-fifth of Astra's standard input and output token prices.

The company lists cached input at $0.10 per million tokens, 95% less than standard input pricing and 50% less than GPT-6 Sol's cached input pricing. The performance comparison is OpenAI's claim.
