NVIDIA's open-source Auto Ontology tries to fix that by giving agents approved definitions to work from, and by showing where each answer came from. ## Teaching AI Your Numbers ### NVIDIA Auto Ontology: An Open-Source Context Layer That Tells Agents What Your Data Means NVIDIA has released Auto Ontology, an open-source tool that gives AI agents a shared dictionary for company data. It records what each business term means, which database columns hold it, and where the numbers came from. The aim is that an agent's answer about, say, revenue uses an approved definition, not a guess. **What you can do:** If your team plans to let an AI answer questions about its data, start a list of the metrics people argue about, and write down one agreed definition for each.

Users report the invite links are full or broken. A wider release after Thanksgiving is only reported by a secondary source, so treat that date as unconfirmed until Nous says it itself.

It reports typical code uploads got nearly five times faster. These are OpenAI's own figures, and Pando is not available outside the company.

A spokesperson cited productivity and risk management and said the experimentation phase is over. The bank has not published its rules or named an incident.

You ask your AI assistant for a floorplan, and it draws a zoomable map of your app with plain-English names. A built-in Health check looks for common mistakes, such as secret keys exposed in the browser. Its author calls it a check, not an audit. **What you can do:** If you built an app with AI help, try it on a small project first, read the Health findings with care, and keep your normal security review.
