AIME2026

Description

AIME2026 is an environment for evaluating mathematical reasoning on 30 problems from the American Invitational Mathematics Examination 2026. AIME is a prestigious invitational competition for high school students who scored in the top 2.5% on the AMC 10/12. Problems cover algebra, geometry, number theory, combinatorics, and calculus, with integer answers validated via symbolic mathematical equivalence.

Capabilities

• High school competition mathematics at AIME difficulty
• Integer answer validation with symbolic equivalence checking
• Coverage of algebra, geometry, number theory, combinatorics, and calculus

Compute Requirements

Agents are given a standard environment with no sandbox or file system access.

Tasks

There is one split in this environment:

• test: 30 tasks

Each problem requires an integer answer (typical range: 0-999).

Reward Structure

Single-turn evaluation with deterministic grading. The agent submits an answer via the answer tool. The answer is verified using the math_verify library for symbolic mathematical equivalence. Reward is 1.0 if correct, 0.0 if incorrect.

Data

aime_2026_problems.parquet (30 problems). Stored on the OpenReward platform.

Tools

Time Horizon

Single-turn. The agent reads the problem and submits one answer.

Environment Difficulty

AIME 2026 represents standard AIME difficulty. MathArena evaluates frontier models:

Top reasoning models now achieve near-perfect scores on AIME-level problems.

Other Environment Requirements

There are no further environment requirements; AIME2026 works out of the box with the OpenReward endpoint without any external API keys.

Safety

Agents in AIME2026 solve competition mathematics problems in a standard environment. The environment does not present direct safety risks.
