## In brief

DeepSeek has launched a code agent that competes with Claude Code. In addition, Beacon, an open‑source tool with self‑improving memory for agents, is number 1 on Product Hunt. New tools such as agent‑leftovers and Arvre help respectively with cleaning up agents’ cloud resources and managing Claude Code sessions. Finally, Nvidia released a new open transcription model and a post‑mortem appeared about a hack of the Claude Code Cursor extension.
