Providing Technical Support for 'Generative AI Hackathon' Hosted by Kansai Electric Power. Implementation Results of 'Space-Understanding AI' Gather in a High-Performance GPU Environment.

VOLTMIND Co., Ltd. (Headquarters: Osaka City, Osaka Prefecture; Representative Director: Seishi Kitamori; hereinafter "the Company") participated as an organizing supporter and technical partner, as well as a judge, in the "Kansai Electric Power KOI x VOLTMIND Generative AI Hackathon: Understanding 'Space' - Space Sensing x Generative AI," hosted by Kansai Electric Power Co., Inc. (Headquarters: Osaka City, Osaka Prefecture; Director, Representative Executive Officer and President: Nozomu Mori; hereinafter "Kansai Electric Power"), aimed at developing next-generation AI models.

Based on our knowledge cultivated through previous hackathon support, we supported the speedy implementation and result creation of participating engineers by providing a high-performance GPU environment and technical mentoring.

◼︎ Background / Overview Under the mission of "fundamentally improving the experiential value of life with cutting-edge technology," our company promotes the popularization of AI-driven development and supports its practical application. In this hackathon hosted by Kansai Electric Power, we participated as a technical partner, leveraging our technical capabilities in AI implementation and our extensive experience in supporting hackathons, to hold the event at the open innovation hub "enellege."

We were consistently involved from the creation of themes and judging frameworks to the final presentation, and we supported the prototype development of participating teams by providing GPU environments.

◼︎ Features of this Hackathon We provided participating teams with a GPU environment of the "NVIDIA H100" and "NVIDIA RTX A5000" class, which are adopted in the field of cutting-edge AI development, free of charge for up to three weeks. By opening up one of the largest computational resources for a domestic hackathon event, we created an environment where participants could challenge full-scale AI development, such as fine-tuning large-scale models and processing massive datasets.

◼︎ Activities Our company went beyond progress coordination and handled the design and operation of the computational infrastructure, allowing participants to focus on development. In planning and design, we were involved in setting the cutting-edge theme of "Space Sensing x Generative AI" and formulating judging criteria. In terms of infrastructure, in addition to providing servers equipped with "NVIDIA H100" and "NVIDIA RTX A5000," we optimized job management on shared servers to provide a fair and stable GPU development environment for all participating teams. During the development period, we supported the teams' implementation by responding to flexible resource allocation changes and advanced technical consultations. We also set up a Discord server for participants and quantified their contributions within the community using our own metrics, which were reflected in the judging for special awards.

At the final presentation on March 28, 2026, at Kansai Electric Power's enellege in Osaka, a total of 9 teams participating in this hackathon showcased working prototypes. A wide range of approaches were presented, from applications in the energy sector to video analysis, disaster prevention, and everyday peace of mind, and the Grand Prix, Excellence Awards, and Special Awards were selected.

Judging was conducted based on the content presented by each team at this final presentation, using five criteria: "Originality," "Business Viability," "Technical Capability," "Presentation Skills," and "Demonstration Skills," with particular emphasis on "Originality" and "Technical Capability."

- Originality Whether there are challenging ideas such as new perspectives, problem settings, data utilization methods, and model designs for the theme of "understanding space."

- Business Viability Whether it specifically demonstrates what kind of value can be created in the real world and industrial fields.

- Technical Capability In addition to the logicality of handling sensor data, model design, learning strategies, and evaluation methods, whether large-scale data processing utilizing the GPU environment, utilization of foundation models, and fine-tuning are performed appropriately. - Presentation Skills Whether the problem setting, technical approach, results, limitations, and future prospects are explained clearly and understandably.

- Demonstration Skills Whether actions and results that make one actually feel "understanding space" are shown, and whether there is persuasiveness and impact as a prototype.

We supported participating engineers from a technical aspect so they could overcome hurdles relying on AI, while also sharing perspectives on practical utilization, ensuring that this event was realized as a hackathon that steps deeply into implementation.

◼︎ From Kansai Electric Power Co., Inc. This hackathon was planned and held with the desire to liven up the engineer community in Kansai and to develop our open innovation hub "enellege" into a place where engineers can mutually improve themselves and co-create and broadcast. During the hackathon, witnessing the participants' passion and curiosity for technology, their technical and co-creative capabilities, and their high-level deliverables, we were once again strongly reminded of the immense potential power generated by new technologies and communities. VOLTMIND powerfully supported us in specialized areas that are difficult for our company to realize alone, through technical support including the provision of GPUs.
