Amazon Bedrock announces up to 80% lower prices for OpenAI GPT‑5.6 models

Today, OpenAI announced lower prices for GPT‑5.6 Luna and GPT‑5.6 Terra. Effective July 30, 2026, on-demand inference prices on Amazon Bedrock for GPT‑5.6 Luna are reduced by 80%, while prices for GPT‑5.6 Terra are reduced by 20%. These reductions are in-line with OpenAI's first-party pricing changes for these models.

GPT‑5.6 Luna is optimized for fast, high-volume workloads and can use tools to complete multi-step workflows, making it well suited for content processing, classification, customer-service automation, and routine implementation tasks. GPT‑5.6 Terra balances intelligence, speed, and cost for everyday production workloads requiring more sophisticated reasoning. These price reductions enable customers to apply their capabilities across more applications, process larger workloads, and lower the cost per completed task. Pricing for GPT‑5.6 Sol remains unchanged. The new prices apply automatically, with no changes required from customers.
