Beating AI Express News: AI programming firm Cognition has rolled out Memory and Dreaming features for its AI coding agent Devin. Memory enables Devin to retain user preferences, corrections, and project experience across sessions, while Dreaming automatically reorganizes these memories in the background daily. Users can directly view what Devin has memorized, as well as recent modifications made by Dreaming. These memories are stored in a personal Memory Drive, essentially a persistent Git repository, with content organized primarily in Markdown files. A short MEMORY.md file serves as an entry point and index, loaded into the context at the start of each new session. Devin then searches for relevant memory files based on the current task, similar to how it queries code repositories, eliminating the need to feed the entire memory bank into prompts. Multiple Devin sessions can read and write to the same memory set simultaneously. Each session has its own Git checkout; after modifying memories, changes are committed and merged back into the Memory Drive. In case of concurrent edits, Git flags conflicts, preventing sessions from overwriting each other’s work. Dreaming itself is a background session that runs automatically daily. It reviews past conversations and existing memories, merges duplicate content, deletes temporary or long-unused information, and fills in previously unrecorded experience. Cognition has also open-sourced this framework as the Agent Memory Repo. Other agents like Claude Code and Cursor can similarly store long-term memories as files and manage them via Git. However, the open-source version only provides the memory structure and workflow; features like Devin’s daily automatic Dreaming run require additional configuration.

Beating AI News: McDonald’s AI Pricing System Faces Antitrust Lawsuit An Illinois customer named Michael Thomas has sued McDonald’s in Chicago federal court, seeking to file a class-action lawsuit on behalf of potentially millions of U.S. consumers. The complaint alleges the fast-food giant used AI to coordinate menu prices between its franchise and company-owned locations, violating U.S. antitrust laws. The suit claims McDonald’s aggregated non-public transaction data from all its stores into a single machine learning “pricing engine” to provide price recommendations to each location. The plaintiff argues franchisees are independent competitors that should set their own prices, adding that pooling rival data and issuing recommendations via a single system could reduce existing price competition between stores. The complaint also directly cites a prior Reuters investigation into the system. McDonald’s denied the allegations, calling the claims “speculative and based on a misunderstanding of the facts.” The company emphasized the AI does not directly set prices for Big Macs or other menu items, noting franchisees retain final pricing authority. McDonald’s previously also published a statement clarifying that price recommendations are merely advisory, and franchisees may choose not to adopt them.

ECB Executive Board member Piero Cipollone stated that the digital euro will help enhance the competitiveness of European banks. Cipollone said on Tuesday that the digital euro project is not merely intended to fill current gaps in Europe’s payment system. “It is also an opportunity to look ahead and provide an innovative platform. New opportunities are emerging constantly, and we want to ensure European payment service providers have full capability to seize these opportunities and build strong competitive advantages,” he noted. The European Central Bank plans to officially launch the digital euro in 2029, with a pilot phase set to begin next year. The project aims to safeguard Europe’s monetary sovereignty. At present, Europe remains highly dependent on U.S. payment companies like Visa and Mastercard, and the growing development of dollar-pegged stablecoins has further intensified concerns among European policymakers.
