AgentFlo built always-on AI sales agents on Amazon Bedrock AgentCore and the Strands Agents SDK. Amazon Bedrock Guardrails can be configured for code generation workflows with coding assistants like Claude Code, Kiro, and OpenAI Codex. Amazon Bedrock introduced API keys for authenticating API calls, generated from the console or API. Short-term Bedrock API keys are valid for the console session or up to 12 hours, whichever is shorter. Long-term Bedrock API keys allow defining validity duration and managing keys from the AWS IAM console. Bedrock API key authentication is available in AWS GovCloud (US) and commercial AWS Regions where Bedrock is available. Amazon Bedrock introduced a Reserved Service tier targeting 99.5% uptime, available for Anthropic Claude Sonnet 4.5. Bedrock Reserved tier automatically overflows to pay-as-you-go Standard tier when capacity exceeds reserved limits. OpenAI's Daybreak Red and Daybreak Blue models are now available on Amazon Bedrock to eligible customers. Daybreak is OpenAI's cyber defense initiative providing defenders governed access to frontier AI including agentic tooling and red teaming.
