OpenAI slashes GPT-5.6 API prices, launches Fast mode

OpenAI announced major API price cuts across its GPT-5.6 model family, dropping GPT-5.6 Luna prices by 80% and GPT-5.6 Terra by 20%. The update also introduces a Fast mode for flagship GPT-5.6 Sol, offering up to 2.5x execution speed at twice the standard cost.

// ANALYSIS

OpenAI's aggressive price reductions and specialized performance modes aim to capture both high-volume background processing and latency-sensitive enterprise agent applications.

–The 80% price drop for GPT-5.6 Luna makes high-volume classification, extraction, and routine tasks exceptionally cheap to run at scale.
–A 20% price cut on GPT-5.6 Terra improves cost efficiency for complex mid-tier reasoning and tool-calling agentic workflows.
–Fast mode for GPT-5.6 Sol offers developer teams a high-throughput option for user-facing interactive applications where response speed is paramount.
