OpenAI's frontier output token pricing, currently around $10–50 per million for top-tier models like GPT-6 Sol and Astra, has faced sharp downward pressure from efficiency gains and competition. Recent 20–80% cuts on the GPT-5.6 family, including Luna dropping to $1.20 per million output, reflect aggressive responses to Anthropic and broader market dynamics, with traders noting sustained declines through improved inference and scaling. High-valuation funding and official API updates reinforce expectations of further reductions by year-end, though resolution hinges on whether new flagship releases maintain or exceed current efficiency trends amid regulatory and capability milestones.
