OpenAI launched GPT-6 Astra on September 3, 2026, as its flagship large language model with official API pricing fixed at $50 per million output tokens (paired with $10 input), positioning it as the highest-capability option for complex computer-use, coding, research, and professional workflows. The model’s 1.05-million-token context, advanced reasoning controls, and benchmark leadership in areas like ARC-AGI and computer-use tasks support this premium rate, which matches certain competing frontier models while exceeding the new GPT-6 Sol ($10 output) and GPT-6 Luna ($0.50 output) siblings released September 22. Traders are watching for potential promotional cuts, tiered adjustments, or competitive responses through year-end, given OpenAI’s history of price reductions on prior flagships and the rapid expansion of lower-cost alternatives in the same family.
