OpenAI GPT-6 Models Cut API Prices by 50%

OpenAI launched GPT-6 Sol and GPT-6 Luna, expanding its lower-cost AI API lineup based on GPT-6 Astra technology. GPT-6 Sol targets advanced coding and professional workloads, while GPT-6 Luna is designed for fast, large-scale everyday tasks. GPT-6 Sol costs $2 per million input tokens and $10 per million output tokens. GPT-6 Luna costs $0.10 per million input tokens and $0.50 per million output tokens. OpenAI says both models are about 50% cheaper than GPT-5.6 promotional rates and well below GPT-6 Astra’s pricing. The new models also reportedly reduce coding deception and factual errors. Sol’s coding deception rate fell from 10.4% with GPT-5.6 to 1.3%, while Luna’s dropped from 9.5% to 2.8%. OpenAI reported stronger results in coding, computer use and professional-work benchmarks. GPT-6 Sol and GPT-6 Luna are available through the API, ChatGPT Work and Codex for eligible paid and education subscribers. Free and Go users can initially test Luna through the desktop app. The GPT-6 launch could lower AI deployment costs, intensify competition across the AI infrastructure sector and increase demand for computing capacity. It has no direct effect on cryptocurrency prices, but traders may monitor related technology and semiconductor stocks.
