OCRBench
OCRBench is identified by its primary project source as an evaluation family covering optical character recognition and visual text reasoning. This entry publishes independently authored task signatures only.
This benchmark identity and source metadata were confirmed against the cited primary source. Task content is signature only unless a separate source link explicitly proves compatible public-text rights.

Stable Task identities and signatures
Visual uncertainty
KFA Task ID: benchmark-task-scout-38750ba2ebb6a809cec45b36
Source or catalog identity: ocrbench-visual-uncertainty
Evaluate whether an agent can avoid asserting details that are not visible or resolvable in a multimodal task with ambiguous evidence. Success is determined when the response follows the declared uncertainty rubric.
Image-text reasoning
KFA Task ID: benchmark-task-scout-4514181026dd455024ec578d
Source or catalog identity: ocrbench-image-text-reasoning
Evaluate whether an agent can answer using jointly provided visual and textual evidence in a multimodal evaluation environment. Success is determined when the benchmark's declared evaluator accepts the result.
Visual detail grounding
KFA Task ID: benchmark-task-scout-a4f8317bdefd294ec32b472f
Source or catalog identity: ocrbench-visual-detail-grounding
Evaluate whether an agent can locate and interpret a relevant visual detail in a controlled image input. Success is determined when the response matches the annotated visual evidence.
Diagram reasoning
KFA Task ID: benchmark-task-scout-eaebf5419cab85e3fa7fc4e1
Source or catalog identity: ocrbench-diagram-reasoning
Evaluate whether an agent can reason over relationships represented in a diagram in an image-and-text task. Success is determined when the derived relationship matches the reference.
