HMMT-Nov-2025#

Overview#

HMMT November 2025 (MathArena) is a challenging evaluation benchmark derived from the Harvard-MIT Mathematics Tournament (HMMT) November 2025 competition, one of the most prestigious and difficult high school math contests globally. It is a different contest from HMMT February 2025 (hmmt25).

Task Description#

  • Task Type: Competition Mathematics Problem Solving

  • Input: HMMT-level mathematical problem

  • Output: Answer with step-by-step reasoning

  • Domain: Algebra, Combinatorics, Geometry, and Number Theory

Key Features#

  • 30 problems from the HMMT November 2025 competition

  • Sourced from the MathArena hmmt_nov_2025 dataset and mirrored on ModelScope

  • Highly challenging competition-level problems

  • Tests advanced mathematical reasoning

  • Represents elite high school mathematics difficulty

Evaluation Notes#

  • Default configuration loads evalscope/hmmt_nov_2025 from ModelScope and evaluates the train split

  • Default configuration uses 0-shot evaluation

  • Answers should be formatted within \boxed{} for proper extraction

  • Numeric accuracy uses mathematical equivalence checking for integers, fractions, decimals, and symbolic expressions

  • No additional runtime dependencies are required

Usage#

Using CLI#

evalscope eval \
    --model YOUR_MODEL \
    --api-url OPENAI_API_COMPAT_URL \
    --api-key EMPTY_TOKEN \
    --datasets hmmt_nov25 \
    --limit 10  # Remove this line for formal evaluation

Using 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=['hmmt_nov25'],
    limit=10,  # Remove this line for formal evaluation
)

run_task(task_cfg=task_cfg)
