The company assures that the lower prices for Luna and Terra are also taken into account in paid subscriptions when using Codex and ChatGPT Work.
Starting July 30, the API price is $2 per million input tokens and $12 per million output tokens for Terra, and $0.2 per million input tokens and $1.20 per million output tokens for Luna. However, the prices for the Sol model remain unchanged.
«ChatGPT and Codex subscription prices and quota budgets remain unchanged, while Terra and Luna usage now consumes fewer credits. The pricing changes will go live on AWS today,» the company added.
GPT-5.6 Terra and Luna remain available in ChatGPT Work, Codex, and the OpenAI API. In ChatGPT Work and Codex, Free and Go users can access Terra, while Plus, Pro, Business, and Enterprise users can choose Terra and Luna.
Among other innovations, OpenAI is introducing a fast mode to the API, particularly for GPT-5.6 Sol. Fast mode is set to provide up to 2,5x faster processing speed at twice the cost. Queries tagged with «priority» will automatically use fast mode.
As you know, on June 26, OpenAI released three new models of the GPT-5.6 series — Sol, Luna, and Terra.
