OpenAI launches faster and more efficient GPT-6 Sol and Luna models.

The two models come packaged with GPT-6 Astra’s advancements in professional work, accuracy, coding, computer use, and alignment, but with higher usage limits and lower costs, according to OpenAI.

ChatGPT Plus, Pro, Business, Enterprise, and Edu customers can access both models in ChatGPT Work and Codex, while free and Go users can only use GPT-6 Luna.
