- Review six blinded AI deliverables (labelled A–F) for that matter
- Make five head-to-head comparisons against a common comparator output
- Write a short, specific rationale for every preference
Practice scope
Acqui-hire merger review, seller disclosure schedules, Rule 144A/Reg S closing opinions, and Series B venture financing opinions.
Requirements
- Qualified lawyer with substantive practice experience in the areas above
- Able to judge work product holistically — correctness, completeness, judgment, usefulness
- Precise written English
- Able to work independently to written instructions and a deadline
Logistics
- Commitment: ~24 hours across the engagement
