TechCrunch: Amex introduces a framework to prevent AI agents from making unauthorized purchases
American Express is introducing a new framework designed to ensure AI agents only make purchases their users have authorized, potentially preventing costly mistakes and disputes as AI-powered shopping grows.
Personal AI agents are increasingly making purchases on behalf of users, but large language models can malfunction and complete unauthorized transactions. American Express has introduced the "Intent Intelligence Framework," which captures and authenticates a customer's purchase instructions before an AI agent completes a transaction, ensuring the purchase aligns with what the customer authorized. The framework works by collecting the customer's purchase instructions and constraints through an API, having the customer authenticate and sign off on the intent, then creating a unique token that the agent uses at checkout instead of the customer's actual credit card number. This approach helps prevent mistakes before they occur, such as an agent purchasing from the wrong merchant, and could also support fraud prevention and dispute resolution as agentic commerce scales.

University of Michigan spinout Laplace Intelligence uses AI agents and interactive simulation to stress-test robots and self-driving vehicles before deployment. The profitable startup is competing at TechCrunch Disrupt's Startup Battlefield.

Epic Games is shifting to an "AI first" development strategy for its collaboration with the Walt Disney Company, letting AI models write all the code and guide all the artwork for an upcoming shooter. That's according to a Bloomberg report, which cites unnamed people familiar with the project who commented on the significant pivot in internal development at the Unreal Engine maker. Human developers will be tasked with managing and guiding code and art assets generated by models such as Anthropic

As enterprises move from debating artificial intelligence adoption to deploying it, AI governance has become the harder question. Autonomous agents now run around the clock across a sprawl of platforms, and controls built for deterministic software were never designed for them. At Dell Technologies Inc.’s “AI Leadership Symposium,” cost and control were recurring themes in enterprise […] The post AI governance shifts to runtime as always-on agents spread appeared first on

Facebook's new "Your Algorithm" feature will let you directly add and manage topics you want to see in your feed and Facebook Reels. Meta says your recommendations "respond right away" after you make updates using the new feature by hitting "interested" or "not interested" for different topics. Your Algorithm previously launched on Instagram earlier this year, and Meta also launched a similar "Dear Algo" feature on Threads. Facebook users will be able to access Your Algorithm
