What is Docling?

Docling is turning a document parser into a general ingestion layer — video now included.

Docling ships a tight semantic-release train, roughly weekly, where each version pairs one or two format or pipeline features with a long tail of fidelity fixes. The fixes are the real product: reading order in docx lists, section headers and footers, ODF text after inline elements, PPTX shapes in visual order, dehyphenation of hard continuations. Alongside the library, a service layer is taking shape — chunking options and targets, PDF heading-level inference, and batch connector sources are all being exposed through the service API rather than only the Python interface.

What is NVIDIA NeMo?

NeMo split itself apart: the flagship repo is now a speech toolkit and nothing else.

NeMo has spent the last six months on a controlled demolition. The 2.7.0 notes warned that avlm, diffusion, llm, multimodal, nlp, speechlm, vision and vlm collections would be removed; NeMo Speech 3.0 executed it, splitting the repository, renaming it to NVIDIA-NeMo/Speech and moving everything non-speech to sibling repos. The release removed 800k lines of deprecated code, moved to uv for installs, cut dependencies and shipped lighter containers. Patch releases in between were security fixes and CUDA binding repairs.

Docling is turning a document parser into a general ingestion layer — video now included.

◆ Current state

Docling ships a tight semantic-release train, roughly weekly, where each version pairs one or two format or pipeline features with a long tail of fidelity fixes. The fixes are the real product: reading order in docx lists, section headers and footers, ODF text after inline elements, PPTX shapes in visual order, dehyphenation of hard continuations. Alongside the library, a service layer is taking shape — chunking options and targets, PDF heading-level inference, and batch connector sources are all being exposed through the service API rather than only the Python interface.

◆ Where it's heading

Format coverage is expanding outward from PDF and Office into anything an enterprise has lying around: legacy binary Office formats, an EBCDIC backend for mainframe data, and video as a declared input format with ASR presets behind it. The model layer is broadening in parallel — RapidOCR refactored to resolve all PP-OCR languages, a layout-driven OCR pipeline with configurable modes, and VLM output now carrying OpenAI logprobs through to predictions. Packaging is being taken seriously too, with chart extraction lazy-loaded so the slim build needs no torch, and agent skills shipped for driving Docling directly.

◆ Prediction

With VideoPipeline declared and ASR presets in place, the next step is likely fleshing out what a video actually converts into — transcript segments tied to frames — rather than adding another document format.

3.8

NeMo split itself apart: the flagship repo is now a speech toolkit and nothing else.

◆ Current state

NeMo has spent the last six months on a controlled demolition. The 2.7.0 notes warned that avlm, diffusion, llm, multimodal, nlp, speechlm, vision and vlm collections would be removed; NeMo Speech 3.0 executed it, splitting the repository, renaming it to NVIDIA-NeMo/Speech and moving everything non-speech to sibling repos. The release removed 800k lines of deprecated code, moved to uv for installs, cut dependencies and shipped lighter containers. Patch releases in between were security fixes and CUDA binding repairs.

◆ Where it's heading

This is a scope decision, not a cleanup. NeMo is trading its position as a general-purpose model framework for a defensible one as the speech toolkit — ASR, TTS, speaker tasks and SpeechLM — and accepting a hard migration for everyone else. The feature work that did ship in 2.7.0 points the same way: streaming speech translation, per-stream phrase boosting, and new streaming ASR and multilingual TTS models.

◆ Prediction

With the split done, expect the next releases to be speech-model drops rather than framework changes, and the separated repos to start versioning independently.
