Paper argues calibration should sit beside accuracy in model evaluations

What this means for you

Nothing to install — this is a reporting argument, not a metric or a tool. But if your pipeline leans on confidence scores (LLM-as-a-judge, synthetic data, active learning), the paper's point applies: most benchmarks, it says, already record a confidence score and a correctness judgement. Nobody reports them.

A position paper posted to arXiv on 21 September argues that language model evaluations should report calibration — how closely a model's expressed or implied confidence matches whether it is actually right — alongside the accuracy each benchmark already tracks. Standard calibration metrics need only two inputs per example, a confidence score and a correctness judgement, and the authors say most benchmarks already record both, so the number could be reported now. The paper asks each subfield to pair its main metric with a calibration score, and says the two inputs remain undefined for open-ended generation.

Key facts

  • ·The paper is posted on arXiv as 2609.26489, dated 21 September 2026, and argues calibration should be treated as an essential property of every model rather than a niche topic. source
  • ·Standard calibration metrics require two inputs per example: a confidence score and a correctness judgement. source
  • ·The authors state that most benchmarks in use today already provide both inputs, so calibration can be reported immediately. source
  • ·For open-ended generation, the paper says defining those two inputs remains an open challenge. source
  • ·The paper names LLM-as-a-judge, synthetic data generation and active learning as research methods that assume calibrated confidence without verifying it. source
