INTRODUCING HOME MCP: ENABLING YOUR AGENT TO INTERACT WITH YOUR HOME

Google has opened early access to Model Context Protocol for Google Home in English for Google Home Premium Advanced users in the US. Any agent that supports calling MCP tools can now interact with all of the devices and event history in the Google Home ecosystem. The MCP allows agents to analyze and answer questions about home activity, summarize camera footage across rooms, manage devices, and create smart home dashboards using everyday language. It contains safety protections, such as prohibiting sensitive actions like unlocking doors, but depending on the agent, using the MCP can result in unexpected or even undesired behavior.

TRAINING A 4B MODEL TO PRODUCE 81% FASTER QUERY PLANS THAN POSTGRES

Query optimizers continue to leave much to be desired despite an enormous body of research. A Postgres database should know everything about the stuff that lives in its tables, but the problem is enormously hard. What's not as hard is verifying whether a query plan an optimizer picks is good or not. Language models are particularly good at learning how to do tasks with easily verifiable outputs. A small, open-weights model can be post-trained via supervised fine-tuning and agentic reinforcement learning to produce Postgres query plans that beat Postgres' default plans.

READ THE HISTORY, NOT JUST THE CODE

Code can't explain things like the history can. You can't understand a codebase from its current state alone. AI models have no commit history. Nobody wrote down why it does things, so researchers have to reconstruct its thought processes from whatever traces are available.

JUDGE ORDERS DATA SHARING AND OTHER FIXES TO SOLVE GOOGLE'S AD TECH MONOPOLY

While Google isn't required to break up its ad tech business, judges have mandated changes to the company's practices. The changes largely align with recommendations made by Google and the Justice Department to correct the company's monopolistic behavior. Google will make its ad pricing more transparent to marketers and rival ad businesses, and appoint a trustee to oversee the changes.
