GPT-6 Sol and Luna join the OpenAI API with two price points
OpenAI has released GPT-6 Sol and GPT-6 Luna through the Responses and Chat Completions APIs. Sol targets complex coding and agentic work, while Luna is priced for focused, high-volume tasks. Both accept text and images and return text. Developers should compare total task cost, long-context pricing and tool support before replacing existing models.
