In the authors’ words

We present the Chinese Elementary School Math Word Problems (CMATH) dataset, comprising 1.7k elementary school-level math word problems with detailed annotations, source from actual Chinese workbooks and exams. This dataset aims to provide a benchmark tool for assessing the following question: to what grade level of elementary school math do the abilities of popular large language models (LLMs) correspond? We evaluate a variety of popular LLMs, including both commercial and open-source options, and discover that only GPT-4 achieves success (accuracy ≥ 60%) across all six elementary school grades, while other models falter at different grade levels. Furthermore, we assess the robustness of several top-performing LLMs by augmenting the original problems in the CMATH dataset with distracting information. Our findings reveal that GPT-4 is able to maintains robustness, while other model fail. We anticipate that our study will expose limitations in LLMs' arithmetic and reasoning capabilities, and promote their ongoing development and advancement.

ERNIE-4.5-300B-A47B leads with 96.7% among models released by April 2026

Best score per model as labs report them in their own cards. Labs pick their own settings, so these compare less cleanly than independent runs.

The newest model with a score here came out in April 2026, and nobody has reported a newer one. Among the 20 highest-ranked models on the capability index, these have no score yet:

  1. 1 ERNIE-4.5-300B-A47B 96.7%
  2. 2 DeepSeek-V4-Pro 90.9%
  3. 3 DeepSeek-V3 90.7%
  4. 4 DeepSeek-V2 (MoE-236B, May 2024) 81.9%
  5. 5 Moonlight-16B-A3B 81.1%
  6. 6 DeepSeek LLM 67B 80.3%

4 models have held number one in labs’ own numbers since its release in June 2023

Lab claims count from the day the card came out, independent runs from the model’s release.
