What is Docling?

Docling keeps swallowing new formats, and now the parsing engines behind them are swappable.

Docling releases every three to four days, alternating feature drops with tight fix releases. The current one is purely corrective: DOCX headings detected by outline level when the style is not literally named Heading, Markdown tables keeping their last cell without a trailing pipe, and the service client serializing engine options in full. Format coverage now spans PDF, Office, ODF, HTML, JATS, email, audio and video.

What is Snorkel AI?

Snorkel has stopped labeling data and started defining what agent competence means.

The output is a research and benchmarking program, not a release feed. Recent work argues that single-episode benchmarks measure the wrong thing: agents should be scored across dependent states, tool calls, simulated users, approval rules, and learning carried between tasks. Concrete artifacts back the argument — Senior SWE-Bench with 100 tasks from real pull requests and half the set held private, GDPval+ for professional reasoning, and collaboration on Agents' Last Exam with Berkeley RDI. Alongside these, Snorkel publishes head-to-head evaluations of frontier model releases and hosts a reading group that surfaces outside research.

6.3

Docling keeps swallowing new formats, and now the parsing engines behind them are swappable.

◆ Current state

Docling releases every three to four days, alternating feature drops with tight fix releases. The current one is purely corrective: DOCX headings detected by outline level when the style is not literally named Heading, Markdown tables keeping their last cell without a trailing pipe, and the service client serializing engine options in full. Format coverage now spans PDF, Office, ODF, HTML, JATS, email, audio and video.

◆ Where it's heading

The engine layer is where the interesting movement is. Docling is shifting from one opinionated pipeline to a set of interchangeable layout, table and OCR backends the caller picks per run, which turns the library into a harness for models rather than a fixed parser. A second thread: the project shipped agent skills for itself in v2.118.0 and a separate docling-client package in v2.120.0, both pointing at being consumed programmatically rather than only imported. The structural-inference work — heading levels from font weight, now from DOCX outline levels — shows the parser learning to read documents that never declared their own structure.

◆ Prediction

Expect the engine-selection surface to keep widening, with OCR joining layout and table structure as a CLI-selectable backend. The steady stream of format-specific crash fixes suggests coverage is outrunning hardening, so more of these short corrective releases are likely between feature drops.

5.0

Snorkel has stopped labeling data and started defining what agent competence means.

◆ Current state

The output is a research and benchmarking program, not a release feed. Recent work argues that single-episode benchmarks measure the wrong thing: agents should be scored across dependent states, tool calls, simulated users, approval rules, and learning carried between tasks. Concrete artifacts back the argument — Senior SWE-Bench with 100 tasks from real pull requests and half the set held private, GDPval+ for professional reasoning, and collaboration on Agents' Last Exam with Berkeley RDI. Alongside these, Snorkel publishes head-to-head evaluations of frontier model releases and hosts a reading group that surfaces outside research.

◆ Where it's heading

Snorkel is moving from evaluation-as-scoring to evaluation-as-training signal: the milestone framing scores intermediate progress, the continual-learning thread treats improvement across a task sequence as the measured quantity, and the newest reading-group post pushes further upstream still, into how much a reasoning model should be trained before it is tested. Publishing benchmarks with private splits and running public model comparisons builds the position that Snorkel is the neutral scorer, which is what makes the enterprise environments business defensible. The through-line is that measurement, not model capability, is the bottleneck.

◆ Prediction

Expect the milestone and continual-learning threads to converge into a named benchmark or environment suite with the same public-private split as Senior SWE-Bench. The feed carries research, talks, and reading-group recaps rather than platform releases, so it does not indicate what ships in the product.
