# PYX Labs

> PYX Labs is an independent research lab that builds benchmarks and expert post-training data for workplace AI. Its benchmarks define what "good" looks like when AI models do work that touches employees — starting with employee listening — with scoring criteria written by industrial-organizational (I-O) psychologists and guidance from academic advisors at Stanford and UT Austin. Research is sponsored by Perceptyx, the employee-experience platform. PYX Labs (pyxlabs.ai) is not affiliated with pyxlabs.com, Pyxl.ai, Pyxant Labs, or Pyxis Lab.

Key facts:
- Flagship benchmark: PYX-Voice, which measures how well frontier AI models perform real employee-listening analysis (interpreting employee survey and feedback data), scored against expert criteria across 84 validated tasks with a public leaderboard.
- Methodology: five steps from real workplace data to a defensible score; criteria authored by practicing I-O psychologists; graded by a cross-vendor judge; results validated against an expert bar.
- Audience: frontier AI labs, workplace/HR AI product builders, academic researchers, and enterprises evaluating AI for employee-facing work.
- Sponsor: Perceptyx (perceptyx.com). Academic advisors at Stanford University and UT Austin.
