# AIME-2026


## Overview

AIME 2026 (American Invitational Mathematics Examination 2026) is a benchmark based on problems from the prestigious AIME competition, one of the most challenging high school mathematics contests in the United States. It tests advanced mathematical reasoning and problem-solving skills.

## Task Description

- **Task Type**: Competition Mathematics Problem Solving
- **Input**: AIME-level mathematical problem
- **Output**: Integer answer (0-999) with step-by-step reasoning
- **Difficulty**: Advanced high school / early undergraduate level

## Key Features

- Problems from AIME I and AIME II 2026 competitions
- Answers are always integers between 0 and 999
- Requires creative mathematical reasoning and problem-solving
- Topics: algebra, geometry, number theory, combinatorics, probability
- Represents top-tier high school mathematics competition difficulty

## Evaluation Notes

- Default configuration uses **0-shot** evaluation
- Answers should be formatted within `\boxed{}` for proper extraction
- Uses LLM-as-judge for mathematical equivalence checking

## Usage

### Using CLI

```bash
evalscope eval \
    --model YOUR_MODEL \
    --api-url OPENAI_API_COMPAT_URL \
    --api-key EMPTY_TOKEN \
    --datasets aime26 \
    --limit 10  # Remove this line for formal evaluation
```

### Using Python

```python
from evalscope import run_task
from evalscope.config import TaskConfig

task_cfg = TaskConfig(
    model='YOUR_MODEL',
    api_url='OPENAI_API_COMPAT_URL',
    api_key='EMPTY_TOKEN',
    datasets=['aime26'],
    limit=10,  # Remove this line for formal evaluation
)

run_task(task_cfg=task_cfg)
```
