Amazon Bedrock AgentCore runtime adds Session endpoints for live web app previews

Amazon’s Bedrock AgentCore runtime now exposes Session endpoints that give each agent session an authenticated URL which forwards HTTP(S), WebSocket and gRPC traffic to allowed ports inside the session. The capability lets coding agents run a live dev server (the blog shows a Vite example) so developers can interact with and watch changes stream into a browser without full redeploys; the SDK surfaces the URL in an X‑Amzn‑Bedrock‑AgentCore‑Runtime‑Session‑Endpoint‑Url header and requests are authenticated via SigV4 or an inbound JWT.

AWS updates Bedrock, AgentCore, and Strands — OpenAI models on Bedrock and new agent tooling (Sep 2026)

AWS announced September 2026 updates to Amazon Bedrock, Bedrock AgentCore, and the open-source Strands toolkit: Amazon Bedrock Managed Agents (powered by OpenAI) entered public preview; the AgentCore runtime reduced cold-start latency and memory overhead for serverless agents; Strands released an open-source harness that uses ~28% fewer tokens and the Decider 2B local decision model (~115 ms); and OpenAI’s Astra, Sol, and Luna families (including GPT-6 Astra and Astra Ultrafast) became available on Bedrock alongside updated Claude versions (Fable 5.1, Opus 5.5).

Wood Mackenzie builds shared APEX agent platform on Amazon Bedrock AgentCore (GA Oct 2025)

Wood Mackenzie describes APEX (Agentic Platform for Energy eXperience), a shared enterprise agent runtime built on Amazon Bedrock AgentCore to avoid duplicated infrastructure across teams. The post explains why the team chose AgentCore (managed platform, model-agnostic, supports multiple agent frameworks and protocols, and reached GA in October 2025 with VPC/PrivateLink/CloudFormation support), and how APEX Studio centralizes observability, identity, scaling, and governance for internal and external agent apps like Woody and Lens AI.
