The framework builds an ontology from enterprise metadata and lets agents generate SQL against certified business definitions. The default LLM is nvidia/nemotron-3-nano-30b-a3b, with Nemotron embedding and reranking models, and it can run via Docker Compose locally or on Kubernetes with Helm, using hosted or self‑hosted NVIDIA NIM endpoints.\n\nNVIDIA’s own testing claims the tool cuts ontology‑creation time by 90%, though no public text‑to‑SQL accuracy scores have been released. The MCP server exposes nine read‑only tools, including askquestion that returns answer, SQL and rows, with a 100‑row cap. An evaluation harness ships with datasets such as BIRD Dev (1,534 questions, 11 databases) and Mini‑Dev (500 questions), but the benchmark relies on deterministic execution rather than LLM judges. Users can integrate any OpenAI‑compatible endpoint, and the source code, containers and docs are available on GitHub.","keyPoints":["NVIDIA’s Auto Ontology library cuts ontology creation time by 90% in its own testing.","Default model is nvidia/nemotron-3-nano-30b-a3b; the stack runs on Docker Compose or Kubernetes via Helm.","The MCP server provides nine read‑only tools, but no public text‑to‑SQL accuracy scores have been published."],"whyItMatters":"A fast, open semantic layer lets AI agents reliably generate SQL from enterprise data, lowering integration effort and improving data governance for businesses.","category":{"slug":"agents","name":"Agents & Tools","url":"https://digestai.news/category/agents"},"entities":{"companies":["NVIDIA"],"models":["nvidia/nemotron-3-nano-30b-a3b"],"people":[]},"firstPublishedAt":"2026-11-02T07:47:12Z","updatedAt":"2026-11-02T07:47:12Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"MarkTechPost","title":"NVIDIA Releases Auto Ontology: An Open Semantic Layer That Grounds AI Agent SQL","url":"https://marktechpost.com/2026/11/01/nvidia-auto-ontology-open-source-semantic-layer-ai-agents","publishedAt":"2026-11-02T07:47:12Z","type":"press","primary":false,"lead":true}],"sourceNotes":null,"discussions":[],"thread":null,"cite":{"text":"Digest AI, \"NVIDIA releases Auto Ontology, an open semantic layer for AI agents\", 2 November 2026, https://digestai.news/story/nvidia-releases-auto-ontology-an-open-semantic-layer-for-ai-agents","publisher":"Digest AI","title":"NVIDIA releases Auto Ontology, an open semantic layer for AI agents","datePublished":"2026-11-02T07:47:12Z","url":"https://digestai.news/story/nvidia-releases-auto-ontology-an-open-semantic-layer-for-ai-agents"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
