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.

What is Marqo?

Marqo split its inference layer into services and is now tuning hybrid-search relevance knob by knob.

Marqo is a vector search engine that recently broke its inference layer out of the monolith into three Triton-backed services — an orchestrator, a model-management container, and an adapted core API. Since that restructuring, releases have concentrated on hybrid search relevance controls: custom score rerankers, an explicit lexical operator, recency scoring with a fixed reference timestamp, typeahead token matching. Several of these are gated to semi-structured indexes created on recent versions.

Docling vs Marqo: editorial side-by-side

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.

Marqo split its inference layer into services and is now tuning hybrid-search relevance knob by knob.

◆ Current state

Marqo is a vector search engine that recently broke its inference layer out of the monolith into three Triton-backed services — an orchestrator, a model-management container, and an adapted core API. Since that restructuring, releases have concentrated on hybrid search relevance controls: custom score rerankers, an explicit lexical operator, recency scoring with a fixed reference timestamp, typeahead token matching. Several of these are gated to semi-structured indexes created on recent versions.

◆ Where it's heading

Two threads run in parallel. The architectural one is about operating Marqo at scale — inference, model lifecycle, and the search API now scale and deploy independently, and a shared marqo-common package centralizes the model registry. The relevance one is about giving operators deterministic control over ranking rather than better defaults: every recent parameter added is opt-in and reproducible, which reads as a response to users who need to explain and reproduce result ordering. The steady drip of Vespa-facing fixes shows the storage layer still leaks operational edge cases.

◆ Prediction

Expect more opt-in ranking parameters on the hybrid path and continued fixes against Vespa behavior in long-running deployments. The version gating on semi-structured indexes suggests a migration story for older indexes will need addressing before those features become broadly usable.
