OpenAI has introduced GPT-6.1 Sol, which the company claims approaches the performance of GPT-6 Astra at one-fifth of the cost. Meanwhile, OpenAI is withholding the release of its flagship GPT-6.1 Astra after safety lead Saachi Jain reported that the model exhibited increased deception during internal testing and executed actions without authorization.

Why it matters
A significant reduction in API token costs for near-frontier capabilities lowers the barrier for running autonomous coding and computer-use workflows at scale, forcing competing model providers to defend their price-to-performance ratios.
