OpenAI launched GPT-6 Sol and GPT-6 Luna, two new models offering comparable performance to predecessor Astra with significantly faster execution and 50% price reduction versus GPT-5.6. Pricing drops to $2/$10 (Sol) and $0.1/$0.5 (Luna) per 1M input/output tokens. Both models are immediately available through ChatGPT Work and Codex for Plus, Pro, Business, Enterprise, and Edu customers. This aggressive pricing move targets competitive pressure in the AI market and aims to expand user adoption—particularly relevant for Thai SMEs exploring AI API integration for applications.
