What is OpenRouter?

OpenRouter is climbing from neutral routing toward owning the model-choice decision.

Recent work extends the platform in two directions. Modality coverage keeps widening, with a dedicated images endpoint, audio transcription, and a LangChain package published on both PyPI and npm, all reachable with the same key and billing. Alongside it sits an analytics layer: Classifiers tag every generation by department, task type or agent complexity against a user-defined taxonomy, and Ori Eval turns model selection into a measured comparison.

What is Docling?

Docling keeps widening what counts as a document — now video, charts, and agent skills.

Docling ships roughly weekly, and each release adds input surface rather than polish. In six versions it picked up a video pipeline and InputFormat.VIDEO, legacy binary Office formats, an EBCDIC backend, a BoxNote backend, and native chart parsing across Word, Excel and PowerPoint that keeps the underlying data instead of a rendered image. Fix lists are long and concentrated in the DOCX, ODF and PDF backends, which is where format edge cases actually live.

OpenRouter vs Docling: editorial side-by-side

OpenRouter is climbing from neutral routing toward owning the model-choice decision.

◆ Current state

Recent work extends the platform in two directions. Modality coverage keeps widening, with a dedicated images endpoint, audio transcription, and a LangChain package published on both PyPI and npm, all reachable with the same key and billing. Alongside it sits an analytics layer: Classifiers tag every generation by department, task type or agent complexity against a user-defined taxonomy, and Ori Eval turns model selection into a measured comparison.

◆ Where it's heading

The modality additions keep OpenRouter substitutable for a direct provider integration, which is table stakes. The more consequential thread is the data OpenRouter accumulates by sitting in the middle: Classifiers make that traffic legible as cost and activity, and Ori Eval sells it back as a recommendation. The company is converting its position as a pass-through into a position as the place where model decisions get made.

◆ Prediction

Expect evaluation and classification to merge into routing itself, so that policies pick models automatically against measured cost and quality rather than leaving the choice to a developer's configuration.

Docling keeps widening what counts as a document — now video, charts, and agent skills.

◆ Current state

Docling ships roughly weekly, and each release adds input surface rather than polish. In six versions it picked up a video pipeline and InputFormat.VIDEO, legacy binary Office formats, an EBCDIC backend, a BoxNote backend, and native chart parsing across Word, Excel and PowerPoint that keeps the underlying data instead of a rendered image. Fix lists are long and concentrated in the DOCX, ODF and PDF backends, which is where format edge cases actually live.

◆ Where it's heading

Two arcs run in parallel. The conversion core is becoming format-omnivorous — charts, video, mainframe encodings, archive formats — while the service layer grows the plumbing to run it at scale: chunking options and targets, generic batch connector sources, GCS, Azure Blob and Google Drive as both source and target. The agent skills in v2.118.0 point at a third arc: making Docling something an agent drives directly rather than a library a developer wires up.

◆ Prediction

Expect the video pipeline to fill out using the ASR presets already in the tree, and the service layer to keep absorbing storage backends. The agent-skills entry suggests more agent-facing packaging is next.
