Your photos, your AWS account — Argentic is on AWS Builder Center

I built an iOS photo backup where your own AWS account is the backend: no servers, on-device semantic search, a Bedrock agent in your pocket, ~$0.35/month. The full architecture story is now published on AWS Builder Center.

Can your robot's brain live in the cloud?

Wafer-scale inference on Bedrock and open 3T-class models both landed this month. Neither will run your robot's control loop — but together they redraw the line between what a robot computes on-board and what it can safely delegate to the cloud.

Kimi K3 — the first open 3T-class model, explained

Moonshot AI shipped a 2.8-trillion-parameter open-weight model with a 1M-token context, native vision, and a new attention stack. What's actually new in the architecture, what the benchmarks say, and why it matters for builders.

Wiring AWS DevOps Agent into ServiceNow: The Observability-to-ITSM Loop

The layered AIOps pattern that displaces a legacy alert-correlation engine: CloudWatch and OpenTelemetry for telemetry, AWS DevOps Agent for autonomous RCA, ServiceNow as the system of record with write-back. Here's how the layers actually connect.

AWS DevOps Agent: Build vs Buy for Enterprise AIOps

AWS DevOps Agent is GA and included with Support plans. But it doesn't replace your custom agents -- it complements them. Here's the hybrid pattern: what to buy, what to build, and how MCP bridges the gap.

The Agent Memory Problem: Why 5+ Solutions Exist and None Won

Mem0, Letta, Zep, graph-RAG, Neptune Memory, HiveMemory, Obsidian steering files -- the agent memory space is fragmenting faster than it's converging. Here's a landscape analysis of why no single solution wins, the four types of memory agents actually need, and a decision framework for choosing your architecture.

MCP Gateway as Policy Enforcement Point: RBAC for Your Agent's Tool Access

Your AI agent has access to tools that perform real actions -- approving expenses, querying databases, modifying infrastructure. Prompt-based guardrails don't survive adversarial inputs. Here's how AgentCore Gateway + Cedar policies create a deterministic enforcement layer that operates independently of the agent's reasoning.

AWS Agent Toolkit GA: How I Gave an Agent 15,000 AWS APIs Without Losing Sleep

AWS released the Agent Toolkit for AWS on May 6, 2026 -- a managed MCP server exposing the full AWS API surface to autonomous agents. I shipped an infrastructure agent the same week. Here's the two-phase safety pattern that lets you hand an agent the keys to your account without waking up to a $10K bill.

When Your AI Agent Runs Away: 204 PRs, $900 Wasted, and the 3-Layer Fix

I woke up to 204 pull requests from a single autonomous agent running overnight. 12 hours, ~$900 in Bedrock tokens, 509 failed builds, zero features shipped. Prompt-only safeguards all failed. Here's the 3-layer fix — hard kill switch, atomic circuit breakers, drift observability — that now prevents runaway agents.

The Agent Memory Stack: Shipping Parallel Projects with Kiro CLI and Obsidian

AI agents forget everything between sessions. Your calendar lies. Your brain doesn't scale past a handful of active projects. Here's the three-layer memory stack I built with Kiro CLI + Obsidian to ship a dozen-plus projects in parallel without cross-contamination.

Boulder — The Self-Replicating AI Build Factory on AWS

Boulder is a meta-orchestrator that spawns AI workers on ECS Fargate to autonomously write, deploy and self-heal full-stack apps on Amplify Gen 2. Here is the architecture, the decisions, and why every serious AI agent system eventually converges on SQS + Bedrock + IAM.
