TL;DR

Vendor-funded benchmarks are marketing. Practitioner-led benchmarks are evidence. A new wave of independent scorecards - run by lawyers, not by analysts on vendor retainers - is becoming the real gate between vendors and buy-side counsel.

1) Why vendor benchmarks lie

Vendors design tests where their tool wins. They pick the jurisdictions, the doc types, the evaluation rubric, and - quietly - the comparison set. Then they publish a chart with a green bar.

The result: every vendor claims to be #1. By definition, six of them are wrong.

2) Practitioner-led scorecards

legalbenchmarks.ai - lawyer-led, public methodology, tasks drawn from real practice.

Vals AI / VLAIR - blind auto-evaluation across multiple legal AI products, using rubrics designed by practicing attorneys.

Both refuse vendor money. That's the entire point.

3) How to read a benchmark

• Who funded it?

• Are the test cases public?

• Are the graders disclosed?

• Is the methodology reproducible?

• Are confidence intervals shown - or just point estimates?

• Did the losing vendors get a chance to respond?

Rule of thumb

If a vendor refuses to participate in independent benchmarks, that is your benchmark.
