What is Docling?

Docling ships a native PDF pipeline and Apple Pages support while maturing its VLM integration layer.

Docling is releasing almost daily, expanding its supported document format surface with each version. Recent additions include a native PDF pipeline, completed Apple Pages support, JATS external hyperlinks, LaTeX output, and CUDA support for RapidOCR on ONNX Runtime. Threaded docling-parse is now the default, and VLM backends (Chandra, Unlimited-OCR) are getting tighter version management and error handling.

What is OpenRouter?

OpenRouter launches Batch API for half-price async inference while building out its decision model catalog.

OpenRouter is an LLM routing layer expanding in two directions: a new Batch API offering half-price inference for workloads that can tolerate 24-hour turnaround, and a growing catalog of decision models (Jev) that return typed probabilities instead of prose. The Batch API emerged from a two-week beta with 230k+ completed batches at a median of 7 minutes. The platform's content cadence has shifted toward developer tutorials and model comparisons, reflecting a growing education investment alongside catalog additions.

Docling vs OpenRouter: editorial side-by-side

Docling

5.0

Docling ships a native PDF pipeline and Apple Pages support while maturing its VLM integration layer.

◆ Current state

Docling is releasing almost daily, expanding its supported document format surface with each version. Recent additions include a native PDF pipeline, completed Apple Pages support, JATS external hyperlinks, LaTeX output, and CUDA support for RapidOCR on ONNX Runtime. Threaded docling-parse is now the default, and VLM backends (Chandra, Unlimited-OCR) are getting tighter version management and error handling.

◆ Where it's heading

Docling is converging on a universal document parsing pipeline — every major format (PDF, DOCX, PPTX, Apple Pages, AsciiDoc, WebVTT, EBCDIC, JATS) processed through a single interface, with multiple output formats (Markdown, JSON, LaTeX). The VLM integration is moving from experimental to production-ready as the team adds CUDA hardware support, min-version enforcement, and format-specific model handling. Scientific document workflows are an emerging target given the LaTeX output and JATS support.

◆ Prediction

The experimental two-stage VLM pipeline will stabilize into a production path in the next few releases. Scientific document ingestion (LaTeX, JATS, math-heavy PDFs) will likely become a promoted use case as the output format support deepens.

10.0

OpenRouter launches Batch API for half-price async inference while building out its decision model catalog.

◆ Current state

OpenRouter is an LLM routing layer expanding in two directions: a new Batch API offering half-price inference for workloads that can tolerate 24-hour turnaround, and a growing catalog of decision models (Jev) that return typed probabilities instead of prose. The Batch API emerged from a two-week beta with 230k+ completed batches at a median of 7 minutes. The platform's content cadence has shifted toward developer tutorials and model comparisons, reflecting a growing education investment alongside catalog additions.

◆ Where it's heading

OpenRouter is moving beyond pure model routing toward an inference optimization layer. The Batch API is the clearest signal: a pricing tradeoff that makes cost-sensitive bulk workloads viable on the platform for the first time. The volume of Jev-related content — five entries in a week — suggests a formal push to make typed decision models a first-class primitive alongside generative ones. The platform is positioning as the place to run all inference, synchronous or async, generative or structured.

◆ Prediction

Given the Batch API beta scale and the sustained Jev content push, the next likely move is either an SDK or dashboard feature that surfaces per-workload cost-vs-latency tradeoffs and routes automatically between sync and batch — or a more formal tiering of the decision model category in the model browser.
