AI BriefingLlamaIndex launches OpenDocRouter to unify document parsing across frontier and open-source models
Key point
The new platform offers token-based billing with $5 in free credits for new accounts and supports synchronous parsing for documents up to 50 pages.
Details
LlamaIndex has launched OpenDocRouter, a platform designed to simplify document-to-markdown parsing by providing a single API for both frontier and open-source models. The service addresses the fragmentation in the OCR landscape, where developers previously had to manage individual prompts, rate limits, and deployments for each new model release.
Unified API and Model Selection
The API accepts PDFs, images, or URLs and allows users to toggle between synchronous responses (for documents up to 50 pages) and asynchronous jobs (for up to 500 pages or 50MB). At launch, the platform supports a curated set of models benchmarked on ParseBench, including:
- Frontier Models: Claude Opus 5.5, Gemini 3 Flash, Gemini 3.8 Flash, GPT-5.6 Terra, GPT-6 Luna.
- Open-Source Models: Infinity-Parser2-Flash, MinerU2.5-Pro, TeleOCR, dots.mocr, PaddleOCR-VL-1.6.
Standardized Layout and Grounding
To address inconsistencies in how different models handle document structure, OpenDocRouter includes a grounding engine. By setting layout: True, users receive markdown with consistent bounding boxes and layout classes (such as title, table, code, and formula) regardless of the underlying model. This ensures uniform output structure even when switching between models with varying native capabilities.
Pricing and Availability
The platform uses pure token-based billing with no minimum commitments. New accounts receive $5 in credits, and paid top-ups start at $10 plus a 5% processing fee. Enabling the layout feature adds $0.20 per million tokens. Failed pages are not charged. Pricing varies significantly by model; for example, GPT-6 Luna costs $0.80 per 1,000 pages on ParseBench, while Claude Opus 5.5 costs $48.82 per 1,000 pages.
OpenDocRouter is distinct from LlamaIndex's existing LlamaParse service, which offers managed tiers, enterprise controls, and self-hosted options. OpenDocRouter focuses on rapid access to the latest models with pay-as-you-go flexibility.
