Terms of Use

Last updated: 1 May 2026

Inference is a free, online quantitative competition run by April Kidd. By creating an account and participating, you agree to the following.

Accounts

  • One account per person.
  • You must use a valid email address.
  • Your display name must not be offensive. We reserve the right to hide or rename accounts that violate this.

Competition rules

  • You get three submission attempts per round. Your latest submission is the one scored.
  • Discussing problems with others is fine. Submitting identical answers and reasoning as another participant is not.
  • Using LLMs is allowed but discouraged. The point is to learn.
  • We reserve the right to disqualify submissions that appear to be gaming the system (e.g. automated probing of the grader).

Scoring and leaderboard

  • Scoring is final once posted. We may re-score if a grader bug is found, but this is at our discretion.
  • Your display name and scores appear publicly on the leaderboard.
  • There are no prizes unless explicitly announced for a specific season.

Liability

Inference is provided as-is. We don't guarantee uptime, score accuracy, or anything else. This is a free competition for fun and learning.

Changes

We may update these terms. Continued use of the site after changes constitutes acceptance.
