# Hana Ishikawa

Evaluations Editor

Tokyo, Japan · Joined 2025

Hana edits AgentCrunch's benchmark coverage, digging into what evaluation numbers actually mean — and when they don't mean much at all.

She has a soft spot for reproducibility, unglamorous methodology notes, and any benchmark that punishes a model for confidently making things up.
