Good morning. Here is what mattered in AI today. OpenAI launched ChatGPT Wallet, which lets its Dots agents complete purchases once a user approves each one with a biometric check. LangChain raised $300 million at a $3 billion valuation to grow LangSmith, its platform for running agents across models and clouds. And llama.cpp, the engine behind much of local AI, reached version 1.0 with a promise of a stable API. We also explain DeepMind’s Flamingo model, how AI hearing aids separate speech from noise and how autonomous tractors work.
