Agentic retrieval with LangChain and Amazon Bedrock Knowledge Bases
Build a Retrieval Augmented Generation (RAG) application on Amazon Bedrock Managed Knowledge Base with LangChain, and see how agentic retrieval handles the multi-part questions that single-shot retrieval answers poorly. Run the same query through both paths, read the trace events, and compare what each retrieval path costs.
Downgrading user roles in Amazon Quick
Amazon Quick doesn't offer a direct console path to downgrade a user from Admin or Author to Reader. This post walks through two reliable methods: a manual delete-and-recreate approach and an AWS CLI step-down sequence that downgrades roles safely while preserving asset ownership.
Evaluating multi-agent systems for explainability and helpfulness with Amazon Bedrock AgentCore
Multi-agent systems need deeper guarantees than fluent responses: they must select the right tools, respect constraints, and explain their decisions. Learn how to build a Strands-based multi-agent supply chain decisioning system and evaluate it with Amazon Bedrock AgentCore Evaluations using built-in, custom, and explainability evaluators.
AWS Weekly Roundup: Amazon Bedrock Managed Agents powered by OpenAI, Q3 service availability updates, Kiro workflows, and more (October 5, 2026)
Last week, we announced a public preview of Amazon Bedrock Managed Agents powered by OpenAI, built on a customized version of OpenAI’s Agents API engineered to be AWS-native and integrated with AWS resources. You can now build agents optimized for OpenAI models that run entirely inside AWS with the identities, permissions, and governance controls you
XCOR launches to trace outages in minutes. It still pages engineers
Palo Alto Networks’ Cortex XCOR uses AI SRE agents to root-cause incidents in under three minutes, the company says, so engineers aren’t woken at night.
64 AI Concepts Every Software Engineer Should Know
#187: Part 1 - Generative AI, RAG, AI Agents, and 14 others.
Agents have made CI the bottleneck. Faster pipelines are the wrong fix
Agents pushed CI job volume up 25x at Anthropic. Faster pipelines help, but they still check a repo, not the distributed system it has to work with.
How Vector Database Search Billions of Vectors in Milliseconds
#186: Understand HNSW Graphs, Approximate Nearest Neighbor Search, and Key Parameters Engineers Tune in Production
AI is speeding up exploits. Vulnerability spreadsheets can’t keep up
AI is widening the gap between the CVEs teams find and the ones they can fix. Closing it means asking which flaws attackers can actually reach.
API design was HARD until I learned these 33 concepts
#185: Part 2 - JWT, WebSockets, OpenAPI, and 13 others.
Anthropic’s answer to Dots and Muse is already inside Claude
Claude, Dots, Muse and Grok Bots are competing for work that continues after you log off. The real test is whether users trust them enough to hand over the next job.
GitHub’s advice for its new Copilot feature is to try something else first
GitHub Copilot can now click and type in desktop apps with no API or MCP server. Here’s how approvals, enterprise controls and reliability limits work.
What Kubernetes’ “monolith” lesson means for AI agent harnesses
In this edition of our Road to KubeCon series, Craig McLuckie wants agent harnesses off the laptop, and Koordinator pushes GPU allocation past 95%.
Sweep thousands of leases for compliance using Amazon Quick and the Adjudicated Query pattern
The Adjudicated Query pattern pairs the Amazon Quick chat agent with a bounded MCP server over a deterministic rules engine to deliver provably complete, defensible compliance answers. This post walks through the reference architecture and a deployable AWS CDK sample, using lease compliance as the running example.
Add secure Web Search to Claude Desktop with Amazon Bedrock AgentCore
Claude Desktop on Amazon Bedrock is limited to the model's knowledge cutoff without web search. In this post, we walk through connecting Claude Desktop to Web Search using Amazon Bedrock AgentCore Gateway, with JWT-based inbound authentication through AWS IAM Identity Center and Amazon Cognito.
Fine-tune a search agent with multi-turn RL on Amazon SageMaker AI
Fine-tuning teaches a small search agent your tools and environment, giving it the reliability of a frontier model at lower latency and cost. In this post, we fine-tune an LLM-powered search agent with multi-turn reinforcement learning (MTRL) on Amazon SageMaker AI and share the gains we measured in retrieval quality and reliability.
“No reason why everyone should have an identical Claude experience”: Anthropic’s mods let you change Claude Code’s look and behavior
Claude Code users can now ask it to redesign itself. Mods can rewrite prompts, block tool calls, and redraw the interface, all from a plugin.
K3s vs. K8s: When lightweight Kubernetes distros win (and when they don’t)
Compare K3s vs. K8s to find the best Kubernetes distro for your needs. Explore resource footprints, edge use cases, and key trade-offs.
I struggled with “API design” until I learned these 33 concepts
#184: Part 1 - REST, GraphQL, Authentication, and 14 others.
OpenAI’s always-on agents are free, until one specific thing happens
OpenAI’s always-on Dots agents run without touching usage limits for now, but any task a Dot hands off to Codex or ChatGPT Work still draws from your plan.
