LlamaIndex launches OpenDocRouter, a unified API routing document OCR across many models

AIOpenDocRouter is a unified API and billing interface for document OCR models, ranging from lightweight open-source options like MinerU to frontier VLMs like Opus 5.5. Per the linked post, models are served at cost with a small transaction cut, rate limits are handled, and bounding boxes and layout are offered as a service.

AILlamaIndex has launched OpenDocRouter, a unified API that transcribes documents to markdown across frontier and open-weight models at cost plus a small transaction fee. The service handles rate limits, adds bounding boxes and layout as a service, and will benchmark new OCR models on ParseBench before adding them.

AILlamaIndex announced OpenDocRouter, a single API that routes document parsing requests to any of 10 frontier and open-source models at launch, including Claude Opus 5.5, Gemini 3.8 Flash, GPT-6 Luna, MinerU2.5-Pro, and PaddleOCR-VL-1.6. Users can switch models in one line with the same request and markdown output, and each model is scored on ParseBench for quality and cost. Pricing is per-token, failed pages are not charged, and the service costs $0.86 to $48.82 per 1,000 pages depending on the model.
