Tonight's brief tracks AI Operations / Agent Control, Tools Worth Testing, Model + API Changes, and Small Business Automation. Synthesized Nightly Librarian run with 8 promoted item(s), 40 scored item(s), and 32 rejected item(s). The lead source signal is ChatGPT for Google Sheets exfiltrates workbooks: The ChatGPT for Google Sheets add-on exfiltrates workbook data to external servers. The operator read is Active security risk; changes a near-term decision about AI add-on usage. Supporting context: Streambed – Stream Postgres to Iceberg on S3 (Relevant to anyone running Postgres who wants analytics without a separate ETL pipeline); MiniMax M3 on Vercel AI Gateway (Another 1M-context model option worth tracking). Monitor-only context stays out of the publish list until reviewed: NVIDIA Cosmos 3: Open Omni-model for Physical AI Reasoning (Open model from NVIDIA, worth monitoring); 1-Bit Bonsai Image 4B: Image Generation for Local Devices (Relevant to local AI inference work).
