AWS September AI Builder Updates and Bedrock GPT-6 Cross-Region Inference Now Available

In September 2026, the AWS Machine Learning Blog published an AI developer update roundup covering new developments in Amazon Bedrock, AgentCore, and Strands. Highlights included: Amazon Bedrock launching a public beta of Managed Agents powered by OpenAI; and opening up a batch of new models, including GPT-6 Astra, GPT-6.1 Sol, GPT-6.1 Luna, Claude Opus 5.5, and Kimi K3. The event has since seen new developments: on October 13, 2026, AWS announced that Amazon Bedrock supports calling OpenAI GPT-6 series models via global cross-region inference from Thailand, Malaysia, Singapore, Indonesia, and Taiwan, with GPT-6 Sol and GPT-6 Luna available from all five AWS regions and GPT-6 Astra available from the Asia Pacific (Singapore) region. The main developments so far are the roundup's publication and the opening of GPT-6 series cross-region inference.
