Neurosphere Co., Ltd. (Headquarters: Minato-ku, Tokyo, CEO: Minoru Negoro, hereinafter "Neurosphere") has announced the launch of a development project for an "Industry-Specific LLM" that can securely learn and operate corporate confidential data and unique know-how in a safe environment.
This project addresses the challenges of "information leakage risks" and "excessive performance and high costs of general-purpose models" that have become apparent as the business use of generative AI expands. Based on the knowledge cultivated through AI BPO and AI agent development, Neurosphere aims to provide a lightweight and highly accurate dedicated AI infrastructure tailored to the business and security requirements of each company.
## Background of Development
Generative AI is being introduced in various areas, such as corporate business efficiency, decision-making support, and advanced customer service. On the other hand, as full-scale implementation in practical operations progresses, the challenges of integrating general-purpose AI as it is into operations have also become clear.
First, there is the issue of over-specification of general-purpose models. While models with massive parameters are highly capable, they are unnecessarily heavy when implemented for specific tasks, and are not always optimal in terms of computational costs, response speed, and operational efficiency. Looking at it from the frontline perspective, there are many cases where "it is high-performing but too heavy" or "continuous operation costs do not justify the ROI."
Second, there are concerns about handling corporate confidential information and unique know-how. While the use of large-scale general-purpose AI is becoming common, there is deep-rooted anxiety about inputting important information into external services. Particularly for companies handling customer information, internal documents, business flows, and design information, ensuring security is a prerequisite for implementation.
Given this background, what is currently demanded is a lightweight and optimized dedicated AI that can be operated in a secure environment and has only the necessary functions. To meet this need, Neurosphere has embarked on the development of an "Industry-Specific LLM" that safely incorporates the knowledge and know-how of each company and directly links to business results.
## Three Features of the "Industry-Specific LLM" in Development
1. Achieving both high accuracy and cost efficiency through thorough lightweighting and optimization
In this project, instead of using massive general-purpose models as they are, we will develop a lightweight LLM trained and optimized specifically for industry-specific expertise and company-specific data.
This suppresses unnecessary processing loads while ensuring the response accuracy and processing performance required in practical work. By designing it to meet business requirements rather than an architecture that constantly requires expensive computational resources, we will realize highly cost-effective AI utilization not only at the time of implementation but also for continuous operation.
2. Securing corporate data as "assets" by providing it in a VPC environment
Neurosphere assumes that a dedicated LLM environment for each company will be built on a VPC (Virtual Private Cloud) rather than a public shared environment.
As a result, information held by companies such as manuals, sales insights, response histories, internal documents, and business flows can be securely utilized while being isolated from external environments.
Crucially, rather than consuming this information merely as input data, the accumulated knowledge representing a company's unique strengths can be continuously reflected in the AI and nurtured as its own "asset." Neurosphere positions AI not just as a tool, but as an entity that evolves the company's knowledge base itself.
3. Fundamentally reducing information leakage risks with thorough security measures
The biggest barrier for companies advancing AI implementation is the risk of information leakage. In this project, in addition to the isolated network environment provided by the VPC, we aim to ensure high security by presupposing the use of secure domestic computational infrastructure.
This enables a secure design according to the requirements of each company, even in cases handling highly confidential business data and customer information. By using an architecture that does not rely on shared environments, we aim to realize an AI infrastructure that balances security and practicality and can be implemented in the field.
## Neurosphere's Strength: Implementation power to "embed AI in the field"
Neurosphere's strength lies not merely in developing LLMs.
Through its support of AI agent development that integrates AI into corporate operations and AI BPO that redesigns the roles of humans and AI, the company has accumulated know-how to root AI in actual operational frontlines.
Therefore, in this project as well, we will not stop at mere technology provision, but integrate everything from business process analysis, operation design suitable for AI introduction, to operational improvement after implementation.
