Datalab Lift vs the Field: How a 9B Schema-First Extractor Compares with NuExtract3, LlamaExtract, Marker, and Docling
Datalab launched Lift, a 9-billion-parameter schema-first document extractor that skips intermediate formats and outputs JSON directly from PDFs or images.

- Lift is a 9B-parameter schema-first document extractor that outputs JSON directly from PDFs or images, bypassing intermediate formats like Markdown.
- It competes with NuExtract3, LlamaExtract, Marker, and Docling by promising higher accuracy and lower latency for structured document parsing.
- Datalab claims Lift reduces processing steps by eliminating intermediate conversions, targeting developers in data pipelines and automation workflows.
- Benchmarks are provided but require independent verification for full credibility.
Datalab has introduced Lift, a document extraction tool that takes a PDF or image and a JSON Schema as inputs, then returns structured JSON matching the schema without intermediate steps. Unlike competitors that first convert documents to Markdown or plain text before extraction, Lift processes rendered page images and attempts to emit the final structured output directly. The model is a 9-billion-parameter transformer designed specifically for schema-first extraction tasks.
The company claims Lift outperforms existing tools like NuExtract3, LlamaExtract, Marker, and Docling in accuracy and efficiency for structured document parsing. By eliminating the need for intermediate representations, Lift aims to reduce latency and improve precision in extracting fields such as tables, forms, and invoices. The tool targets developers building data pipelines, document processing systems, and enterprise automation workflows where structured outputs are critical.
Datalab positions Lift as a specialized alternative to general-purpose document parsers, emphasizing its ability to handle complex layouts and nested JSON schemas. The release includes benchmarks comparing Lift against leading open-source and commercial extractors, though independent verification is pending.

Offers a streamlined, schema-first approach to document extraction, reducing pipeline complexity and latency.
Potential cost savings and efficiency gains in document-heavy workflows like invoicing, forms, and data entry.
Advances structured document parsing with a specialized model, challenging established tools.
- schema-first extraction
- A document parsing approach where the target JSON structure is defined first, guiding the extraction process directly.
- intermediate representation
- A temporary format (e.g., Markdown) used during document processing before final structured output.
