Advancing the price-performance frontier with GPT-5.6
OpenAI has reduced prices for its GPT-5.6 Luna and Terra models and introduced a 'Fast mode' for GPT-5.6 Sol. These updates aim to improve price-performance for enterprise AI workloads.
Why it matters
Lower costs enable businesses to implement high-volume AI tasks, such as document analysis and background automations, at a larger scale more affordably.
The details
- GPT-5.6 Luna prices dropped by 80% and GPT-5.6 Terra by 20%.
- Fast mode for Sol offers up to 2.5x faster speeds than Standard processing.
- Luna API pricing is $0.20 per million input and $1.20 output tokens.
