Jij Inc. Launches Invitation-Only Beta of “JijZept AI”

2025/12/25

— A browser-based AI assistant for complex planning and allocation decisions —

Jij Inc. (Headquarters: Minato-ku, Tokyo; CEO: Yu Yamashiro), a provider of mathematical optimization solutions, today announced an invitation-only beta of JijZept AI, a browser-based AI assistant that helps teams apply mathematical optimization to real business planning, allocation, and scheduling.

JijZept AI was previously available as a closed beta to a limited group of partners. This invitation-only beta expands access to a broader audience, including engineers, data scientists, digital transformation leaders, and researchers.

Background: Bringing Optimization to More Teams

Across supply chain, energy, manufacturing, and finance, organizations face complex planning problems under tight constraints. Many teams want to use mathematical optimization, but model design and method selection can be hard to get right, and in-house expertise is often limited.

Jij built JijZept AI to reduce those barriers. As a generative-AI-powered assistant within the broader JijZept platform, it supports the full lifecycle of optimization AI, from early modeling decisions to implementation and ongoing improvement.

About “JijZept AI”

JijZept AI supports both technical and operational work with mathematical optimization. It helps users iterate faster by answering technical questions, suggesting modeling approaches, and providing practical implementation guidance.

Typical use cases include:

  • Answering questions about mathematical optimization and Jij products (e.g., JijZept, JijModeling)

  • Advising on planning and allocation logic, constraint structuring, and common pitfalls

  • Providing implementation examples in Python and JijModeling

  • Helping diagnose why a model is not producing expected results

JijZept AI uses a proprietary knowledge base built from JijModeling use cases and extensive technical documentation. Using embedding-based semantic retrieval, it surfaces relevant information and guidance aligned with the user’s intent.

Key Features (Preview at Beta Launch)

AI Chat-Based Technical Support

  • Q&A from optimization fundamentals through real-world applications

  • Clear explanations of planning, scheduling, and allocation concepts

  • Guidance on model design and frequent failure modes

Modeling and Implementation Support

  • Support for implementing optimization models with JijModeling

  • Guidance for common business problems (e.g., shift scheduling, production planning, inventory and logistics)

  • Help formulating complex constraints

Result Visualization & Python Sandbox Integration (Experimental)

  • Experimental capability to run AI-generated Python code in a secure sandbox

  • Automatic generation of visual outputs, including graphs and Gantt charts

During the beta, access will be rolled out to a limited group of early users.

Note: Features and specifications are subject to change without notice.

Invitation-Only Access

To maintain service quality and operational stability, JijZept AI is currently offered on an invitation-only basis. Invitations will be sent on a rolling basis to:

  • Companies and research institutions engaged in joint research or collaborative projects with Jij

  • Existing JijZept users

  • Participants in Jij-hosted events and seminars

  • Individuals who apply via the pre-registration form

A pre-registration form is available, and access will be granted on a rolling basis.
