OpenAI Cuts GPT-5.6 Luna and Terra API Prices, Expanding Room for Automation
OpenAI has reduced API pricing for its GPT-5.6 Luna and Terra models, a change that can materially lower the cost of AI-powered automation and high-volume workloads. Luna's prices have fallen by 80%, while Terra's have been cut by 20%. The update is a price-performance move rather than a universal increase in usage limits, but it gives teams more economic room to test, refine, and scale…
OpenAI has reduced the API pricing for its GPT-5.6 Luna and Terra models by 80% and 20%, respectively. Luna's price per million input tokens has dropped to $0.20 from a higher rate, while Terra's price per million tokens has fallen to $2 from $2.40. These lower token prices can make AI-powered automation and high-volume workloads more cost-effective, enabling businesses to test, refine, and scale token-intensive processes without significant financial strain.
The updated pricing applies to Luna and Terra across ChatGPT Work, Codex, and the OpenAI API, while the higher-speed GPT-5.6 Sol mode remains at twice the standard price, providing up to 2.5 times faster speeds. While the lower token prices do not guarantee better results, they do improve the economics of testing, making previously marginal use cases more viable.
Businesses should still plan and check the limits and access terms that apply to their own account, region, and product tier before redesigning a workflow around the assumed capacity.
