Abstract
We introduce MMSciCode, a comprehensive expert-level, multilingual multi-discipline benchmark for evaluating foundation models in scientific code generation. It includes 624 expert-annotated research coding problems spanning six core scientific disciplines. Compared to prior benchmarks, MMSciCode features three key advancements. First, it challenges models to integrate domain-specific knowledge with algorithmic reasoning to implement core functions from research papers. Second, each problem is meticulously annotated by domain experts through a rigorous paper-grounded process, with strict quality controls implemented to ensure dataset integrity and authenticity. Finally, each problem is equipped with comprehensive unit test suites and con-tainerized environments, enabling reproducible and diagnostic evaluation of both functional correctness and domain validity. We conduct an extensive evaluation of 23 state-of-the-art foundation models and 2 coding agents on MMSciCode. We identify substantial performance gaps between models and human experts, providing actionable insights for advancing expert-level scientific code generation.
Large Language Models (LLMs) have achieved impressive performance in natural language-to-code generation; however, their ability to follow structured algorithmic reasoning remains insufficiently understood. We introduce Pseudo2Code, a benchmark designed to systematically evaluate the impact of structured pseudocode on code generation quality and algorithmic faithfulness. The benchmark consists of 300 manually validated real-world programming tasks spanning multiple domains and three difficulty levels (Easy, Medium, and Hard). Each task contains a problem description, structured pseudocode, reference implementation, and executable test suite. To ensure benchmark reliability, we adopt a dual-stage human validation protocol and release fully executable benchmark instances. Beyond the benchmark, we propose the Pseudo2Code Agentic Framework, a multi-stage pipeline that leverages pseudocode as an explicit intermediate reasoning representation for code generation. We evaluate both commercial and open-source language models using a rubric-based evaluation framework that measures correctness, completeness, relevance, clarity, reasoning quality, and pseudocode adherence, complemented by execution-based testing. Experimental results demonstrate that the proposed Pseudo2Code Agentic Pipeline consistently outperforms strong commercial and open-source baselines, achieving an overall score of 4.78 compared to 4.31 for the strongest baseline model. Furthermore, a human evaluation study involving 100 benchmark tasks shows strong agreement between human judgments and automated assessments. Our findings provide empirical evidence that structured pseudocode improves functional correctness, reasoning quality, and algorithmic faithfulness in code generation. We release Pseudo2Code to support future research on structured reasoning, interpretable code generation, and reliable AI-assisted software development.

While Large Language Model (LLM) agents excel at monolingual long-horizon planning and tool use, enterprise workflows inherently require processing multilingual resources across extended trajectories. The interaction between multilinguality and long-horizon execution, however, remains underexplored. We introduce PolyWorkBench, a benchmark designed to evaluate LLM agents on multilingual, long-horizon workplace workflows. PolyWorkBench features 67 tasks across five core domains: commerce, knowledge work, legal analysis, localization, and manufacturing. Tasks are authored by the paper's authors from real-world data seeds and independently verified through a second-author audit. Agents must integrate heterogeneous multilingual inputs, execute iterative tool-use trajectories, and produce structured domain artifacts. To rigorously assess performance, we adopt Grade, a task-specific structural scoring rubric, as our primary ranking metric, and complement it with Pytest for executable state verification and LLM-as-Judge for semantic quality diagnostics. Benchmark evaluations reveal that agent performance varies substantially across languages and drops sharply on the harder cross-lingual tasks, and our analysis shows that multilingual execution exposes systematic failure modes across planning, tool interaction, and decision-making in long-horizon agents.

We present L3Cube-IndicQuest v2, a large-scale gold-standard multilingual question-answering benchmark for evaluating the India-specific factual knowledge of Large Language Models (LLMs). The benchmark comprises 3,471 curriculum-grounded English question--answer pairs spanning nine domains, curated from educational curricula, competitive examination materials, and domain-specific reference books. We introduce a practical hybrid construction strategy that combines context-grounded LLM-based question generation and validation with semantic deduplication and human verification, enabling scalable creation of benchmark data while preserving annotation quality. The benchmark is translated into 19 Indic languages, yielding a publicly released multilingual dataset of 69,420 question--answer pairs across 20 languages. We evaluate six LLMs under three protocols: LLM-as-a-judge and two deterministic lexical criteria, exact-substring and word-overlap matching. All three produce almost the same model ranking, showing that the results do not depend on the choice of judge. The frontier commercial model leads by a wide margin, and among open-weight models Gemma4 31B outperforms the Indic-specialised Sarvam 30B in every evaluated Indic language.

Large language models (LLMs) have demonstrated strong performance across a wide range of tasks, but ensuring their reliability in highly technical domains remains a significant challenge. In nuclear engineering, problem solving often requires not only factual knowledge but also quantitative reasoning and conceptual understanding. To address the need for systematic evaluation in this domain, we introduce NuclearQAv2, a benchmark for assessing LLMs on nuclear engineering knowledge. The benchmark comprises approximately 1,240 question-answer pairs spanning three categories: boolean, numeric, and verbal. NuclearQAv2 is constructed using a hybrid pipeline that combines expert-authored questions, existing datasets, and LLM-assisted generation from domain-specific technical corpora. By leveraging structured prompting for both automated question generation and response evaluation, the proposed framework enables scalable benchmark construction and evaluation. We evaluate a diverse set of LLMs using NuclearQAv2 and observe substantial performance differences across task types. While the models generally perform well on factual questions, quantitative reasoning and conceptual understanding remain considerably more challenging. These results highlight the importance of multi-faceted evaluation frameworks and establish NuclearQAv2 as a scalable benchmark for assessing LLM capabilities in technical domains.

Automated fact-checking has become critical in combating misinformation, with Large Language Models (LLMs) emerging as powerful tools for this task. This systematic literature review analyzes how LLMs have been applied to automated fact-checking, identifying effective techniques, persistent challenges, and future directions. Following the PRISMA 2020 protocol, we analyzed 85 studies published between 2018 and 2025, extracted from five academic databases (IEEE Xplore, ACM Digital Library, Scopus, Web of Science, and ScienceDirect). We found that Prompt Engineering (84.7%), Retrieval-Augmented Generation (50.6%), and Fine-tuning (55.3%) dominate the literature. While proprietary models like GPT-4 achieve the highest performance (e.g., 88.5% F1-score), they do so at a significantly higher computational cost compared to classical Transformers. Critically, only 10.6% of the studies address temporality, despite the highly dynamic nature of real-world claims. Although LLMs significantly advance fact-checking, structural challenges persist, primarily hallucinations (48.2%), data scarcity (51.8%), and a lack of temporal awareness (10.6%). To overcome these barriers, we propose a research agenda prioritizing temporal-aware architectures, Small Language Models (SLMs) for sustainable deployment, and human-centered evaluation metrics.

Academic papers are a primary carrier of scientific knowledge, yet most of this knowledge remains locked in PDFs that are optimized for human reading rather than machine use. For Multimodal Large Language Models (MLLMs), the core challenge is not only perception, but representation: scientific pages interleave text with Structured Academic Elements (SAEs) such as tables, formulas, charts, and pseudocode, whose structure, data, and logic are poorly preserved by common surrogates like Markdown. We therefore propose Compilable Academic Document Parsing (CADP), a paradigm that reconstructs a full page as contextual \LaTeX{} plus executable Python, so that structure-preserving elements and executable chart representations can be reconstructed, recompiled, and directly verified against the source page. To support this setting, we introduce CADP-Bench, an expert-verified benchmark of full academic pages containing tightly coupled text and multiple SAE types, evaluated through a re-injection compilation protocol. We further study current capabilities using SOTA MLLMs and an exploratory multi-agent baseline that incorporates common agentic techniques. Results show that even frontier models still struggle to produce high-fidelity executable reconstructions, highlighting substantial room for improvement in structure-aware scientific document parsing. CADP-Bench is released for future research.
