AWS AI Updates: September 9, 2026

1. GPT-6 Astra Lands on Amazon Bedrock With a 1M-Token Input Window

AWS. OpenAI’s GPT-6 Astra is now callable through the Bedrock APIs and the Bedrock console, accepting up to 1 million input tokens per request. AWS positions it for autonomous agents, large document collections, and advanced computer and browser use, and customers can configure ChatGPT Work and Codex to run against the Bedrock-hosted model instead of OpenAI’s own endpoints. Region availability and pricing are deferred to the Bedrock documentation rather than stated in the announcement, and OpenAI is shipping enterprise plugins for ChatGPT Work that extend browser use into common business applications.

2. AgentCore Memory Decouples Long-Term Memory From Conversation Events

AWS. A new IngestData API lets developers submit content straight into Bedrock AgentCore Memory for long-term extraction without first persisting it as a short-term memory event. It accepts both conversational payloads with USER and ASSISTANT roles and raw JSON payloads such as behavioral events and activity logs, each with optional metadata that feeds the extraction pipeline. Resulting records surface through ListMemoryRecords and RetrieveMemoryRecords, with Kinesis streaming for real-time notifications and ListMemoryExtractionJobs for redriving failed extractions. The practical effect is that agents can build durable user profiles from telemetry, not just from chat transcripts. Available in all regions where AgentCore Memory already runs. Source
