Four AI platforms moving from talking to doing. LangChain, the company behind those NYC subway ads, adds AI Search, red teaming and managed agents to LangSmith, and we compare it with Langfuse, Arize, Braintrust and Weights & Biases Weave. Polar, the AI browser from a former Perplexity Comet engineer, runs multi-hour tasks across the sites you're logged into. GitHub's Octoverse finds AI agents now start more than 40% of pull requests, as it launches Copilot Fusion to pick the best model for every step. And your next customer might be an agent: Google opens its Connected Apps Platform for Search and Gemini, Zocdoc lets agents book appointments, and Meta details Andromeda, which scores over a billion ads a second. Plus quick hits: a correction on Mistral Large 4's open weights date, Gemini 4 Carbon, OpenAI and ServiceNow, Claude legal tools, NVIDIA Nemotron 3.5 Transcribe, XREAL AURA glasses, Alexa+ devices, and an AI chip seizure in Malaysia.
