DataSemantics: Automatic Data Integration Powered by LLMs

Hello! We are researchers from the Converging Technologies lab at Fujitsu Research. We are presenting a novel semi-automated solution to the problem of data conversion and integration into desired structures and formats. In data-driven systems, integrating disparate data sources becomes challenging when incoming data doesn’t conform to the system’s data specifications. Despite advances in automated schema matching systems, data integration tasks involving complex semantic interrelationships still require users to manually identify and define elaborate transformations between datasets. This process consumes a huge amount of manual time and effort and remains a bottleneck in modern data integration workflows. Our DataSemantics technology employs an AI-driven human-in-the-loop system to automate the end-to-end data conversion. It uses LLMs to analyze semantic relationships and generate step-by-step transformation pipelines autonomously, while only requesting the user’s attention to resolve specific semantic ambiguities through its user interface.

Generative AI for Software Engineering #3: Test Specification Generation Technology

Hello. We are Taro Togawa and Takao Nakagawa from Artificial Intelligence Laboratory in Fujitsu Research.

To promote the use of generative AI at enterprises, Fujitsu has developed a generative AI framework for enterprises that can flexibly respond to diverse and changing corporate needs and easily comply with the vast amount of data held by a company and laws and regulations. The framework was successively launched in July 2024 as part of Fujitsu Kozuchi (R&D)'s AI service lineup. In this article, we will focus on the transformation in system operations and maintenance brought about by generative AI, and introduce Test Specification Generation Technology, which automates the creation of test cases from existing design documents.

Is GPT-5 Easier to Jailbreak — or Are We Assessing It Wrong? A Comprehensive Assessment of GPT-5 Security Risks Using Fujitsu’s LLM Vulnerability Scanner

Hello, we are Omer and Roman from the Generative AI Trust Research team at Fujitsu’s Data & Security Research Laboratory. We’re excited to share our latest work: the first comprehensive security evaluation of GPT-5, conducted using our Fujitsu's LLM Vulnerability Scanner. This report dives deep into the security posture of GPT-5 and its sibling models, going beyond surface-level jailbreak prompts to examine data leakage and agentic misuse. We also apply a critical lens on how OpenAI’s new alignment strategies are reshaping red-teaming and security standards.

Our key finding: GPT-5’s "Safe-completions" approach to the safety alignment *1, designed to maximize helpfulness within policy boundaries, changes the model’s behavior, and also requires the AI security community to redefine how red-teaming should be conducted. While GPT-5 Full demonstrates strong reasoning, higher robustness in agentic environments, and reduced data leakage, it shows greater susceptibility to malicious prompts compared to GPT-4o, which still relies on an earlier alignment strategy - “refusal-first” *2.

Early reviews of GPT-5 *3, *4 have already claimed it is less safe than GPT-4, pointing to jailbreak successes and toxic outputs. But is GPT-5 truly weaker - or are today’s red-teaming methods, built around refusal detection, missing the bigger picture? We argue that what looks like regression may actually reflect a mismatch between evaluation methods and GPT-5’s new safety alignment paradigm.

This shift highlights a blind spot for current testing. To properly assess GPT-5 ‘Safe-Completions’, red-teaming must evolve beyond refusal testing and instead evaluate how “safe” completions can still enable misuse - whether through partial disclosures, or inconsistent policy application across contexts.

Read on for a full breakdown of our evaluation methodology, key results, and practical recommendations.
