OpenAI released GPT-6.1 Sol, a model that offers performance comparable to GPT-6.0 Astra, especially in coding and intelligence tasks, at a significantly lower cost. The new model costs $0.10 per million tokens, about half the price of GPT-6.0 Astra, and is available to ChatGPT Work, Codex Plus, Pro, Business, Enterprise, and Edu subscribers. OpenAI delayed the release of GPT-6.1 Astra indefinitely due to safety concerns.
