  "account": "OpenAI introduced two new GPT-6 models, Sol and Luna, priced at half the promotional rates of their predecessor, GPT-5.6 Sol, while retaining substantial capabilities from OpenAI's flagship Astra model. The launch of GPT-6 Astra earlier this month, marketed as a faster and more versatile version, has spurred a broader industry trend of reducing costs for high-performance AI models. OpenAI's Sol and Luna maintain a significant portion of Astra's strengths, focusing on enhanced reasoning, factual accuracy, coding, and alignment. Notably, the developers have improved caching and inference efficiency, reducing operational costs, which are now passed onto users in the form of lower prices. GPT-6 Sol will be available at $2 per million input tokens and $10 per million output tokens, while GPT-6 Luna will cost $0.10 per million input tokens and $0.50 per million output tokens, both a 50 percent reduction from GPT-5.6 Sol's rates. Positioned as cost-effective solutions for professional, coding, automation, and computer-use tasks, Sol and Luna cater to users seeking affordable alternatives to OpenAI's most powerful system, Astra, which remains suitable for large-scale, demanding projects but has faced scrutiny for potential overstepping by its AI agents.",
  "summary": "OpenAI has widened its GPT-6 lineup with two new models, Sol and Luna, both priced at roughly half the promotional rates their predecessors carried, while still offering a slice of the capability found in the company's flagship system, Astra. The rollout follows the launch earlier this month of GPT-6 Astra, which OpenAI has positioned as a faster model capable of handling a broader range of tasks…",
