Perception Agents — Antje Barth, Amazon AGI Lab

Jul 23, 2026 · 21:45

Antje Barth of Amazon AGI Lab introduces perception agents — AI that sees and interacts with screens visually rather than through APIs — arguing that while agents can click and type, they fail at end-to-end knowledge work because reliability and trust are missing without verifiable outputs. Unlike coding agents, which succeeded due to unit tests, most work lives in the messy seams of applications where no easy verification exists. Barth's solution is a perception-action loop: the agent perceives the rendered screen, plans, acts, and checks its own work in real time, much like humans collaborating over a shared screen. She demonstrates two open-source tools: an annotation Chrome extension that lets users mark elements and issue precise commands, and a verification tool that checks visual design and user flows against specs. A live demo shows a Bee device capturing a meeting transcript that instantly triggers agent actions and verification. The talk closes with a call to build in the open, emphasizing that shared context between human and agent is the missing piece for reliable, trusted AI assistants.

Building Agents at Cloud Scale — Antje Barth, AWS

AWS Principal Developer Advocate Antje Barth demonstrates how to build and scale AI agents using cloud-native patterns, arguing that specialized agents will reinvent customer experiences. She showcases Alexa Plus, which orchestrates hundreds of expert systems across 600M+ devices and tens of thousands of services, and the Amazon Q Developer CLI agent, shipped in just three weeks. Barth introduces Strands Agents, an open-source Python SDK for building production-ready agents that supports multiple model providers (Claude, Llama, OpenAI) and over 20 prebuilt tools including memory, RAG, and multi-agent workflows. She demonstrates integrating MCP servers via Lambda with DynamoDB for session storage, and previews upcoming A2A protocol support and a future of personal agents connecting to agent stores.

From Software Developer to AI Engineer: Antje Barth

Jul 24, 2024 · 19:48

Antje Barth, a Principal Developer Advocate for generative AI at AWS, outlines five practical steps from software developer to AI engineer: understanding foundation models, getting hands-on with AI developer tools like Amazon Q Developer, prototyping with models via Amazon Bedrock, integrating agents, and staying up to date with community events. She demonstrates Amazon Q Developer's ability to generate, explain, and transform code, reducing unvaluable tasks from 70% to focus on creative work. Barth introduces Amazon Bedrock's unified Converse API for standardized model invocation across providers like Anthropic's Claude 3.5 Sonnet, and shows how agents can be built to control a Minecraft bot through reasoning and tool use. The episode concludes with the announcement of the AI Engineering Hub at the AWS loft in San Francisco for community workshops and events.
