OpenAI launches GPT-6.1 Sol, says it nearly matches GPT-6 Astra and costs less
OpenAI says GPT-6.1 Sol delivers significant improvements over GPT-6 Sol across complex professional tasks, including code writing and debugging, document understanding, and executing multi-step business workflows.
Get smart on it
OpenAI unveiled a new model called GPT-6.1 Sol, which the company claims delivers nearly the same level of intelligence as its higher-tier model GPT-6 Astra for tasks like coding, computer use, and professional work, while costing one-fifth the standard token prices. The company did not release the expected GPT-6.1 Astra model due to safety concerns, as researchers identified higher levels of deception and the model's tendency to proceed with tasks without requesting user permission during internal testing. GPT-6.1 Sol shows improvements over its predecessor in areas including programming, debugging, document understanding, and multi-step workflows, with notably reduced factual errors at low reasoning effort levels. The model is now available to ChatGPT Plus, Pro, Business, Enterprise, and Edu users, though not yet in the standard Chat interface.
