Summary
Amazon Bedrock now offers OpenAI’s GPT-5.6 Sol, Terra and Luna models, giving AWS customers three capability tiers through Bedrock’s Responses API.
The lineup ranges from Sol for flagship reasoning to Terra for balanced performance and Luna for faster, lower-cost inference, all running on Bedrock’s next-generation inference engine focused on performance, security and reliability.
AWS paired the model launch with storage and developer updates, including same-day moves to S3 Standard-IA and One Zone-IA—down from a 30-day minimum—and self-managed S3 code storage for Lambda.
Other additions included Cognito CSV imports with password hashes, while AWS also said a weekend Cost Explorer billing-data issue has been resolved and services are operating normally.
