AI BriefingBenchmarking Document Parser Performance
Key point
ParseBench is a benchmark that evaluates parser accuracy on your own documents using 5 metrics.
Details
LlamaIndex has released ParseBench. The core message is that when comparing document parsing performance, you shouldn't just look at public leaderboards—you should run it directly on your own real documents.
Multiple parsers are evaluated, and the post notes that Gemini 3 Flash, Qwen 3 VL reductor, and others were also tested.
There are 5 evaluation criteria.
- table accuracy
- content faithfulness
- visual grounding
- chart data extraction
- semantic formatting
In other words, it looks not only at structured information like tables and charts, but also at fidelity to the original text, recognition of visual elements, and output formatting. This makes it well suited for verification based on real work documents when adopting or comparing document parsing tools.
A Hugging Face dataset has also been released alongside it, so you can start experimenting right away.
