OpenAI released two cheaper versions of GPT-6 on Tuesday, with pricing roughly half that of GPT-5.6. GPT-6 Luna offers the steepest discounts at $0.10 per million input tokens and $0.50 per million output tokens.

GPT-6 Sol costs $2 per million input tokens and $10 per million output tokens, while the budget-focused GPT-6 Luna comes in at $0.10 and $0.50 respectively. Both models represent approximately 50% savings compared to GPT-5.6 pricing. The dual-tier release strategy allows OpenAI to serve different market segments—Sol for users prioritizing advanced capabilities, Luna for cost-conscious developers and enterprises. The price cuts align with broader industry trends toward more affordable AI access. Competitors including Anthropic and Meta have similarly reduced pricing to expand their customer bases as AI model costs decline through efficiency improvements. OpenAI has not yet disclosed detailed performance comparisons between the models or availability timelines.
