— 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.Pre-register here: https://ai.jijzept.comBackground: Bringing Optimization to More TeamsAcross 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 pitfallsProviding implementation examples in Python and JijModelingHelping diagnose why a model is not producing expected resultsJijZept 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 SupportQ&A from optimization fundamentals through real-world applicationsClear explanations of planning, scheduling, and allocation conceptsGuidance on model design and frequent failure modesModeling and Implementation SupportSupport for implementing optimization models with JijModelingGuidance for common business problems (e.g., shift scheduling, production planning, inventory and logistics)Help formulating complex constraintsResult Visualization & Python Sandbox Integration (Experimental)Experimental capability to run AI-generated Python code in a secure sandboxAutomatic generation of visual outputs, including graphs and Gantt chartsDuring 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 AccessTo 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 JijExisting JijZept usersParticipants in Jij-hosted events and seminarsIndividuals who apply via the pre-registration formA pre-registration form is available, and access will be granted on a rolling basis.JijZept AI: https://ai.jijzept.com/You can join the waiting list via the form highlighted in red.Future RoadmapJij positions JijZept AI as a core component of the broader JijZept optimization AI development platform. Planned updates include:IDE Integration: Conversational support directly within development environments such as Visual Studio CodeRemote MCP: Enabling other AI agents to invoke JijZept AI capabilitiesWorkspace Enhancements: Stronger project sharing for teams and organizationsWorkflow Features: End-to-end support across the optimization project lifecycleDetails on the full feature set and pricing will be announced at the time of the official release.Service OverviewService Name: JijZept AIFormat: Cloud-based AI assistant (web application)Launch Date: December 25, 2025 (invitation-only beta)Target Users:Engineers working on the application of mathematical optimization and advanced operational planningResearchers, data scientists, and analystsBusiness professionals improving operations such as scheduling and inventory managementAccess Method: Access details, including the dedicated URL and registration instructions, will be provided individually to invitation code holders.About Jij Inc.Company Name: Jij Inc.CEO: Yu YamashiroAddress: INDEST Room 403, Innovation Center, Tokyo Science University Tamachi Campus 3-3-6 Shibaura, Minato-ku, Tokyo 108-0023, JapanCorporate Website: https://www.j-ij.com/Founded: November 2018Business Description: Development of algorithms and software for mathematical optimization and quantum computing, and the provision of cloud and professional services designed to support large-scale optimization planningMedia Contact: Jij Inc.
