Overview
Docling Serve wraps the Docling document converter in a FastAPI service: POST a URL or file to /v1/convert/source and get structured text back, with OpenAPI docs at /docs and a playground UI at /ui on port 5001. Container images cover CPU (4.4 GB), CUDA 12.8 (11.4 GB) and CUDA 13.0 on amd64 and arm64; a ROCm image builds locally. Suited to RAG pipelines that need a document-to-text service.
Who it is for: teams needing a document-to-text service for RAG pipelines
Strengths
- Single container with API, OpenAPI docs and a playground UI
- Stable v1 API after migration
- CPU and CUDA 12.8/13.0 images for amd64 and arm64
- Converts from HTTP sources or uploads in one call
Weaknesses
- Images are large: 4.4 GB CPU, 8.7 GB base amd64, 11.4 GB CUDA
- CUDA images carry no latest tag; pin explicit versions
- ROCm image is not published; build it yourself
- Slim images without bundled weights are only announced
What it needs
- GPU optional
- Docker
- Models: bundled Docling parsing models
- port 5001
