Learn to evaluate combinatorial counting in large language models using CombEval, a dynamic benchmark framework

advanced Published 19 Jun 2026
Action Steps
  1. Define a combinatorial counting problem using CombEval's typed Cofola specification
  2. Generate natural-language counting problems with exact solver-verified answers
  3. Evaluate a large language model's performance on the generated problems
  4. Analyze the results to identify areas for improvement
  5. Use CombEval to systematically vary object type, entity scale, and constraints to test the model's robustness
Who Needs to Know This

NLP researchers and engineers can benefit from CombEval to test and improve their language models' counting abilities, while data scientists can use it to generate and evaluate counting problems

Title: CombEval: A Framework for Evaluating Combinatorial Counting in Large Language Models

Abstract:
arXiv:2606.19788v1 Announce Type: new Abstract: We present CombEval, a dynamic benchmark for evaluating combinatorial counting in large language models. CombEval represents each problem as a typed Cofola specification over entities, combinatorial objects, object dependencies, and constraints, enabling controlled generation of natural-language counting problems with exact solver-verified answers. Unlike static collections, CombEval supports systematic variation of object type, entity scale, const
