Highlights for the 26.03 release include:

  • Legacy ingestion repository consolidated under NeMo-Retriever
  • NeMo Retriever Extraction pipeline renamed to NeMo Retriever Library
  • NeMo Retriever Library now supports two deployment options:
  • A new no-container, pip-installable in-process library for development (available on PyPI)
  • Existing production-ready Helm chart with NIMs
  • Added documentation notes on Air-gapped deployment support
  • Added documentation notes on OpenShift support
  • Added support for RTX4500 Pro Blackwell SKU
  • Added support for llama-nemotron-embed-vl-v2 in text and text+image modes
  • New extract methods pdfium_hybrid and ocr target scanned PDFs to improve text and layout extraction from image-based pages
  • VLM-based image caption enhancements:
  • Infographics can be captioned
  • Reasoning mode is configurable
  • Enabled hybrid search with Lancedb
  • Added retrieval_bench subfolder with generalizable agentic retrieval pipeline
  • The project now uses UV as the primary environment and package manager instead of Conda, resulting in faster installs and simpler dependency handling
  • Default TTL for long-running pipeline job state increased from 1–2 hours to 48 hours so long-running jobs (for example, VLM captioning) do not expire before completion
  • NeMo Retriever Library currently does not support image captioning via VLM; this feature will be added in the next release
  • Documentation: multimodal extraction is covered on one page with an in-page table of contents and redirects from the former per-topic URLs
