Karpathy's AI does research now + OpenAI's latest buy

Andrej Karpathy open-sourced 'autoresearch', a 630-line tool enabling AI agents to autonomously conduct ML research by iterating on training code while humans engineer prompts. The system runs 5-minute training cycles with agents automatically optimizing hyperparameters and architecture through autonomous git commits.

Google DeepMind's CSRO framework uses LLMs to generate game-playing strategies as executable code rather than opaque neural networks, achieving competitive performance with traditional RL while producing fully interpretable, human-readable policies that can be inspected and debugged.

Promptfoo

OpenAI is acquiring Promptfoo, an open-source AI testing and security platform used by 130k monthly developers and 25% of Fortune 500 companies, to integrate its adversarial testing and evaluation capabilities into OpenAI's infrastructure while maintaining its open-source status.

Google Merchant Center Help

Google launched the Universal Commerce Protocol (UCP), an open standard enabling AI agents to handle complete shopping journeys including checkout on Google Search and Gemini surfaces, while merchants retain seller-of-record status and customers pay via Google Wallet.

Cursor

Cursor launched 30+ new marketplace plugins from partners like Atlassian, Datadog, and GitLab, extending its AI agent's ability to autonomously interact with development tools by combining MCPs with usage instructions that prove more effective than MCPs alone.
