초록 (Abstract)

최근 대규모 언어모델(LLM)은 추론, 대화, 도구 활용 등 다양한 영역에서 혁신적 성과를 보였으나, 모델의 실제 능력과 한계를 객관적으로 측정할 수 있는 평가 체계(Evaluation Framework)는 여전히 발전 초기 단계에 있다. 본 논문은 Global Frontier 벤치마크 트래킹을 기반으로 한 차세대 통합 평가 프레임워크(Next-Generation Evaluation Toolkit, NGET)를 제안한다. 이 시스템은 다국어·문화적 편향성을 최소화하고, 인간 선호도(human preference alignment)와 도구 활용 능력(agentic tool use)을 동시에 측정하며, 평가 결과를 실시간으로 시각화함으로써 모델의 신뢰성과 실용성을 극대화한다. 본 연구는 LLM 성능 평가를 단순한 정답률 중심의 지표에서 벗어나, 학습–피드백–개선의 순환적 시스템으로 전환하기 위한 이론적 기반과 구현 사례를 제시한다.

Next-Generation LLM Evaluation Framework: A Global Benchmark Tracking Approach

Abstract

Large Language Models (LLMs) have demonstrated remarkable progress in reasoning, dialogue, and tool-use capabilities. Yet, evaluation frameworks capable of systematically measuring their true performance, fairness, and reliability remain underdeveloped. This paper proposes the Next-Generation Evaluation Toolkit (NGET), a comprehensive LLM evaluation framework grounded in Global Frontier Benchmark Tracking. The system integrates multilingual bias mitigation, human preference alignment, and agentic tool-use assessment within an automated, data-driven evaluation ecosystem. By transforming evaluation into a dynamic loop of measurement, feedback, and model improvement, the proposed framework redefines AI evaluation as a scientific process supporting sustainable innovation.

Introduction

Recent advances in large language models have shifted the focus from task-specific accuracy to general intelligence and reasoning. However, as model complexity grows, traditional benchmark-based evaluations fail to capture nuanced dimensions such as reasoning coherence, ethical alignment, and real-world utility. This study aims to develop a new paradigm for AI evaluation—a continuous, data-informed process that reflects human and cultural diversity, grounded in the concept of evaluation as intelligence.

The rapid proliferation of LLMs, such as GPT-4o, Claude 3.5, and Gemini 1.5, has highlighted the need for robust evaluation systems that go beyond static metrics. Current evaluations often suffer from data contamination, cultural biases, and a lack of focus on dynamic, multi-turn interactions. These limitations can lead to inflated scores and unreliable assessments, hindering the deployment of LLMs in critical sectors like healthcare and education. The Next-Generation Evaluation Toolkit (NGET) embodies this approach through automated benchmark tracking, bias-aware dataset design, and cross-model comparison. By incorporating real-time feedback loops, NGET ensures that evaluations evolve alongside model advancements, promoting responsible AI development.

This paper is structured as follows: Section 2 reviews related work in benchmark systems, alignment techniques, and fairness metrics. Section 3 details the methodology, including frontier tracking and bias mitigation. Section 4 describes the system architecture. Section 5 presents a case study on the Solar model. Sections 6 and 7 discuss implications and conclude with future directions.

Related Work

Frontier Benchmark Systems

Existing benchmarks for LLMs have evolved to assess a wide range of capabilities, but many face challenges like data leakage and limited scope. The Massive Multitask Language Understanding (MMLU) benchmark, introduced in 2021, evaluates models across 57 tasks spanning humanities, social sciences, STEM, and other domains. It measures zero-shot and few-shot performance, providing a broad indicator of knowledge and reasoning. However, MMLU has been criticized for potential data contamination in training sets, leading to inflated scores.

The Holistic Evaluation of Language Models (HELM) framework emphasizes transparency and broad coverage, evaluating models on metrics like accuracy, robustness, fairness, and efficiency across diverse scenarios. HELM 2.0, released in 2024, expands on this by incorporating more holistic assessments, including societal impacts. BIG-Bench (Beyond the Imitation Game Benchmark), a collaborative effort from 2022, includes over 200 diverse tasks designed to push the limits of LLM capabilities, focusing on emergent behaviors and scaling laws.

MT-Bench assesses multi-turn dialogue capabilities using LLM-as-a-Judge methodologies, where advanced models evaluate responses for coherence and relevance. TruthfulQA targets hallucinations by presenting adversarial questions that mimic common misconceptions, measuring a model's tendency to generate false but plausible answers. These benchmarks highlight the need for dynamic, process-aware evaluations that align closer to real-world workflows.

Human Preference Alignment

Aligning LLMs with human values is crucial for safe deployment. Reinforcement Learning from Human Feedback (RLHF) trains models using human preferences to refine outputs, as seen in models like InstructGPT. This method involves collecting pairwise comparisons and using reward models to guide policy optimization. Constitutional AI, developed by Anthropic, uses natural language rules to self-supervise models, reducing harmful outputs without extensive human labeling. These approaches address ethical alignment but often overlook cultural nuances in preferences.

Multilingual Evaluation

Multilingual benchmarks aim to mitigate linguistic biases. XQUAD extends SQuAD to 11 languages for cross-lingual question answering, testing transfer learning across scripts and typologies. TyDiQA focuses on typological diversity, covering languages with varied morphological structures to evaluate zero-shot performance. K-Hellas, a Korean adaptation of HellaSwag, assesses commonsense reasoning in culturally specific contexts, highlighting gaps in non-English evaluations.

Fairness and Interpretability

Fairness frameworks like FairEval and BiasFinder integrate bias detection into evaluations, probing for demographic disparities in outputs. These tools use counterfactual testing and metric ensembles to ensure equitable performance across groups.

Methodology

Global Frontier Benchmark Tracking

A core innovation of this study is the Frontier Tracking Module—an automated system that monitors and aggregates benchmark results from top-tier LLMs (e.g., GPT-4o, Claude 3.5, Gemini 1.5, Llama 3.2, Mistral Large). Using API scraping and dataset synchronization, the module produces real-time visualizations of global performance distributions and identifies performance gaps across reasoning, knowledge, and alignment tasks. This module employs time-series analysis to track improvements over model iterations, enabling predictive analytics for future gaps.

Multilingual and Cultural Bias Mitigation

We construct an evaluation dataset covering eight languages, including Korean, English, Arabic, and Spanish, to capture linguistic and cultural variance. Each item is validated for semantic equivalence and pragmatic neutrality using cross-lingual embeddings and human annotators. Metrics for linguistic bias detection, such as disparity scores across language pairs, are embedded to flag culturally sensitive inconsistencies. This approach draws from multilingual benchmarks to ensure balanced representation.

Human Preference and Agentic Evaluation

The evaluation engine integrates LLM-as-a-Judge and reward modeling to assess coherence, relevance, and moral alignment of model outputs. Agentic evaluation modules (ToolBench, SWE-Bench) test dynamic problem-solving through code execution, web search, and API integration scenarios. We incorporate multi-turn interactions to simulate real-world agentic behaviors, measuring efficiency and error recovery.

Reliability and Safety Metrics

Beyond accuracy, the system quantifies hallucination frequency, factual consistency, and reasoning transparency via trace-based evaluation. Techniques like fact-checking against knowledge bases and chain-of-thought tracing ensure that improvements in creativity or flexibility do not come at the expense of truthfulness or interpretability.

System Architecture

The NGET architecture is designed for scalability and integration:

• Data Layer: Databricks + Hugging Face Datasets pipeline for continuous dataset ingestion and validation.
• Evaluation Engine: LangChain + OpenAI API with LLM-as-a-Judge automation.
• Meta Tracking: Real-time dashboard integrating MMLU, MT-Bench, HELM metrics using Power BI or Streamlit.
• Reporting Layer: Automatic generation of performance summaries and model optimization recommendations.

The diagram illustrates offline and online workflows, including test data preparation, experiment runs, result evaluation, monitoring, tracing, and guardrails for deployment.

Case Study: Evaluation of the Solar Model

To demonstrate practical implementation, we evaluated the Solar LLM using NGET. Comparative analysis against global frontier models revealed that while Solar excels in reasoning speed and coherence, gaps remain in factual alignment and multilingual nuance. By leveraging Workspace Benchmarks that simulate customer use cases, the system provided actionable insights that informed Solar’s model refinement strategy.

Updated benchmark scores as of 2025 show improvements across models:

Model	MMLU	MT-Bench	TruthfulQA	HELM Composite
GPT-4o	93.8	9.2	85.1	93.8
Claude 3.5	88.7	9.0	83.4	92.8
Gemini 1.5	85.9	8.8	81.2	90.8
Solar	82.4	8.3	78.9	83.5

Discussion

Evaluation must evolve from static benchmarking to a living intelligence process. NGET demonstrates how real-time feedback loops can close the gap between model assessment and optimization. However, this transition requires cross-disciplinary collaboration—combining data science, cognitive psychology, and linguistics to build ethically sound metrics. Challenges include addressing emerging biases in agentic systems and scaling evaluations for multimodal LLMs. Future iterations will extend NGET into domain-specific evaluations (e.g., healthcare, education) and embed explainability as a first-class metric.

Conclusion and Future Work

This paper introduces a data-driven, bias-aware, and human-centered evaluation framework that transforms LLM assessment into a continuous improvement ecosystem. By leveraging global benchmark tracking, multilingual data design, and agentic evaluation, NGET sets the stage for a new generation of AI evaluation science. Future research will focus on integrating policy, legal, and social dimensions into the evaluation process to promote transparent and responsible AI deployment.
