This contract role asks mathematicians to turn dense informal proofs into structured, machine-checkable Lean 4 formalizations. The work also involves helping AI researchers understand where automated provers fail and how to improve formal verification pipelines. It is aimed at people with strong proof-writing backgrounds who want to work at the intersection of mathematics and AI.
This freelance role asks mathematicians to design demanding problems and reference solutions that test how AI systems reason. The work also includes checking model outputs for accuracy and giving structured feedback, with benchmarks spanning undergraduate to PhD-level material. It suits people with advanced mathematical training who can work independently and remotely.
This role involves evaluating and improving how AI models handle rigorous mathematical reasoning. You will create challenging math problems, review AI solutions for logical errors and unjustified steps, and write correct solutions that serve as training examples for the models to learn from.
This role invites mathematical physicists to contribute to a research benchmark in fundamental physics, designed to assess whether cutting-edge AI models can solve real research problems in physics. You will work on specialized challenges in one of four proposed domains (special functions, integrable systems, permutation combinatorics, conformal geometry), creating, solving, reviewing, or validating problems at the level of academic research.

This ongoing project hires advanced STEM experts to write graduate-level and PhD-level problems with exact, verifiable answers, helping AI systems improve at rigorous scientific reasoning. Participants create original problems in their own specialty, write detailed step-by-step solutions, and sometimes review AI-generated answers to find reasoning errors. It is aimed at PhD candidates and holders, postdoctoral researchers, and faculty in biology, chemistry, physics, mathematics, and selected engineering fields.
