ICYMI: What landed for AI builders in August 2026

Amazon Bedrock announced support for million-token context windows with prompt caching for GPT-5.6 Sol, Terra, and Luna, along with Web Search capabilities.

Cross-Region inference was expanded to over 25 AWS Regions.

OpenAI's Daybreak Red and Daybreak Blue models became available on Amazon Bedrock for eligible customers.

AgentCore runtime instances now support sessions up to 14 days on dedicated EC2 compute, and AgentCore expanded to new regions.

New temporal policies, rate limiting, and AgentCore payments were introduced to control agent behavior and spending.

From the source
GPT-5.6 Sol, Terra, and Luna now support million-token context windows with prompt caching, helping reduce cost and latency when context is reused. Web Search lets the models find current information beyond their training data, incorporate relevant results into their answers, and provide citations without requiring you to integrate a separate search provider.
