Cursor Is Training on Your Feedback

OpenAI is losing the vibe war - Sora got killed, a billion-dollar Disney deal went with it, and Claude is quietly taking over. Anthropic had its own rough week though, with the Claude Code source map leaking and revealing a secret dream mode, a hidden Tamagotchi, and frustration-detection regex. A North Korean hacking group backdoored LiteLLM via a supply chain attack. And finally, Cursor is now shipping four new AI models per day using real-time RL trained on how users actually accept or reject suggestions.
