"We are committed to pushing the model frontier across cost efficiency, capability, and speed. Starting today, we are reducing prices for GPT-5.6 Luna by 80% and GPT-5.6 Terra by 20% , and offering a faster option for GPT-5.6 Sol in the API. Luna and Terra’s lower prices are reflected in how..."
...usage is counted in Codex and ChatGPT Work, so your usage goes further. Along with the price reduction on GPT-5.6 Luna and Terra, Fast mode for GPT-5.6 Sol in the API delivers up to 2.5x the speed of Standard processing at 2x the Standard price.
Fast mode gives API customers faster access to GPT-5.6 Sol, with no change in intelligence. We’re also upgrading Auto-review in the ChatGPT app and Codex CLI from GPT-5.4 to GPT-5.6 Luna.
Combined with Luna’s new price, we expect Auto-review to cost about 10x less, making your agentic workflows more cost-efficient. Making advanced intelligence more abundant and affordable is central to our mission to ensure AGI benefits all of humanity.
With the help of GPT-5.6 Sol, we have made leaps in efficiency.
Today, we are passing those gains on in the API with lower prices for Luna and Terra, and OpenAI @OpenAI · 1h Advancing the price-performance frontier with GPT-5.6 From openai.com 10 11 298 42K — OpenAI
