Microsoft says AI agents are “risky”, but it’s moving ahead with the plan on Windows 11

Microsoft is integrating AI agents into Windows 11, despite acknowledging risks such as hallucinations, unpredictable behavior, and vulnerabilities to cyber threats like Cross Prompt Injection (XPIA). The company plans to transform every Windows 11 PC into an AI-powered machine by introducing features like Copilot Voice, Copilot Vision, and Copilot Actions. The Windows 11 taskbar will feature a new "Ask Copilot" interface for users to interact with AI agents. These agents will operate under separate accounts with limited permissions, controlled folder access, and tamper-evident logs, but still have access to personal folders like Documents and Downloads. The Agent Workspace is a key feature that allows AI agents to perform tasks in a controlled environment, separate from the user's session. Agents can interact with applications and execute multi-step tasks while being monitored. Microsoft employs the Model Context Protocol (MCP) to regulate agent interactions with applications, ensuring security and proper permissions. Despite concerns over privacy and security, Microsoft believes that integrating AI is essential for keeping Windows competitive. The company has faced backlash over previous features like Recall, which raised privacy issues, and must work to rebuild trust with users. The experimental AI features are currently optional, and Microsoft aims to demonstrate their value to encourage acceptance.

How Letta builds production-ready AI agents with Amazon Aurora PostgreSQL

AI agents benefit from persistent memory, enabling them to recall past interactions and maintain context, which enhances customer experience in scenarios like customer service. The Letta Developer Platform allows developers to create stateful agents with advanced context management features. It supports self-hosting within a virtual private cloud and uses Amazon Aurora PostgreSQL for long-term memory storage. Aurora PostgreSQL offers capabilities such as efficient similarity searches with the pgvector extension, sub-second query latency, and dynamic storage scaling. Letta operates as a persistent service, allowing agents to function independently and scale horizontally using Kubernetes. The platform supports multi-tenancy and includes enterprise features for security and monitoring. To set up an Aurora Serverless cluster for Letta, users must create a database on Amazon RDS, configure security group access, and install the pgvector extension. Letta connects to Aurora using a PostgreSQL connection string. After establishing the connection, users can create agents, send messages, and view agent states and conversation histories stored in Aurora. Letta organizes data in 42 tables, including those for agents, messages, and memory blocks. Users can explore the database schema and examine the structure of stored messages and embeddings. Finally, it is recommended to delete the Aurora cluster and associated resources after completing the integration to avoid charges.

Sure, Why Not: Windows 11 AI Agents Might Install Malware On Your PC

Microsoft's recent update highlights the risks associated with its new "Experimental Agentic Features" in AI, which are designed to interact with user applications and files. These AI agents can perform complex tasks but may also produce unexpected outputs and introduce security risks, such as cross-prompt injection (XPIA), leading to potential data exfiltration or malware installation. While Microsoft emphasizes the need for human oversight in AI-generated decisions, concerns about data integrity and system safety persist. The term "hallucinations" is used to describe instances of erroneous outputs from AI, suggesting a broader issue within generative AI technology. Currently, Windows 11’s agentic workspace feature is disabled by default, but the long-term status of this safeguard is uncertain as Microsoft integrates AI further into its products.
