Self-Evaluation Is Already There: Eliciting Latent Judge Calibration in Base LLMs with Minimal Data
Title: Self-Assessment Is Inherent: Extracting Latent Judge Calibration in Foundation Models Using Minimal Data
Abstract: As large language models (LLMs) become increasingly assessed by other models, a critical question emerges: is it possible for a model to forecast how a judge will rate its own generated output? Our research indicates that this capability is largely innate, requiring no specialized training. Even when prompted with few-shot examples, base models demonstrate a strong ability to predict external judges’ multi-attribute quality scores for open-ended responses, performing significantly better than chance across three distinct benchmarks.
To harness this latent potential, we propose Self-Evaluation Elicitation (SEE). This approach unlocks the model's inherent skills through a concise two-stage process. First, a calibration-coupled reinforcement learning phase enhances both the quality of the model’s answers and its ability to predict the judge’s feedback. Second, a masked distillation phase refines the predictive accuracy of the self-evaluation without altering the underlying answers.
SEE achieves these results using only 160 unique examples—a dataset size approximately 31 times smaller than that required by standard reinforcement learning baselines. Despite the minimal data requirement, the method improves calibration on held-out data across all three benchmarks while maintaining high answer quality. Furthermore, the extracted self-evaluation mechanism is tightly integrated into the model’s own token distribution and remains robust across judges it was never explicitly trained to evaluate. This stability suggests that the model has developed a generalizable concept of quality, rather than merely memorizing the preferences of a specific judge. These findings suggest that aligning self-evaluation with judges should be viewed as an elicitation challenge rather than one of knowledge acquisition.
