LlamaIndex has launched OpenDocRouter, a single API for turning PDFs and images into Markdown using different document-parsing models. Its pitch is practical: compare providers on cost and quality without rebuilding the integration for each one.

What happened
The platform offers a shared endpoint for several open-source and frontier models, with a grounding engine intended to keep bounding boxes and layout elements consistent across models. LlamaIndex says users can compare results through its ParseBench tool, including quality and cost for tables, charts and faithfulness.
The launch post names Claude Opus 3.5, Gemini 1.5 Flash and MinerU2.5-Pro among the models available. Billing is token-based at provider rates, with no added markup, and access starts with a $25 credit top-up. Those details come from LlamaIndex’s launch announcement.
Why it matters
Document parsing is often where tidy AI demos meet untidy PDFs. A single API and comparison tool could make it easier for developers to test different models against their own documents, while consistent layout information may help preserve where text and elements appeared on the page.
The announcement describes the platform and its billing, but does not provide independent tests showing which model performs best. ParseBench may help with that comparison; the useful answer will depend on the documents and tasks a team actually cares about.
Our read
This is a substantive developer-tool launch, not merely another model behind a new sign-in screen. The combination of multiple providers, a stated no-markup billing approach and built-in comparisons gives teams a concrete reason to evaluate it. If you rely on document extraction, test your own awkward files before trusting any leaderboard to pick a winner.
What to watch
- Which models are available at launch and how the selection changes.
- Whether ParseBench comparisons match results on real customer documents.
- How the grounding engine handles layout differences between providers.
- Whether token-based billing remains easy to compare across models.
Discussion spark: When choosing a document-parsing model, would you trust a shared benchmark such as ParseBench, or only tests on your own documents?
