Speeding up Docen Parse

How we cut median page latency while improving accuracy.

The problem

Getting parsing throughput right is deceptively hard. The average case is easy; the tail is brutal, and the tail is what breaks pipelines.

What we did

We treated it as a measurement problem first. Before changing the model, we built a labeled set of the hardest examples we could find, so we could tell whether any change actually helped.

From there, the work was iterative: adjust the model, score it on the hard set, keep what moved the number, and throw out what didn't. No change ships without evidence.

• A benchmark built from real, difficult documents.
• Targeted training on the failure cases.
• Confidence signals so downstream systems know when to check.
