Keep control

basebox 1.7.0 extends the Secure AI Stack with an OpenAI-compatible API. This simplifies the integration of self-hosted AI into existing systems—without transferring critical data outside your infrastructure.


Organizations can use AI while maintaining control over data, deployment, and compliance.


Why Integration Was a Challenge


Many AI tools, frameworks, and development environments are built around the OpenAI API standard.


For organizations operating their own infrastructure, this resulted in:

  • additional integration layers

  • adaptation of established workflows

  • increased effort for implementation and maintenance


This leads to higher development effort, longer integration cycles, and increased operational costs.


Who This Is Relevant For


This extension is designed for organizations working with critical data:

  • healthcare

  • public sector

  • financial services

  • critical infrastructure


Typical requirements:

  • no transfer of sensitive data to external services

  • compliance with regulatory frameworks (e.g. GDPR, ISO 27001)

  • operation in controlled environments (on-premises, air-gapped, private cloud)


OpenAI-Compatible API: Standard Instead of Custom Integration


With basebox 1.7.0, an OpenAI-compatible API is available.


This enables:

  • direct use of existing libraries and SDKs

  • integration into development environments without changing application logic

  • reuse of established tutorials and implementations


Supported core functions:

  • chat completions

  • streaming

  • tool calls

  • model discovery


Integration into Established Development Environments


The API is compatible with tools and workflows based on the OpenAI standard.


Typical use cases:

  • integration into IDEs

  • development of custom applications using existing SDKs

  • automation of processes with AI functionality


Integration effort is reduced to configuration instead of development.


Infrastructure Remains Unchanged


The OpenAI-compatible API extends the existing architecture.


Key aspects:

  • the GraphQL API remains fully available

  • no migration of current applications required

  • both interfaces access the same infrastructure


Organizations can continue using existing integrations while adopting standardized interfaces.


Test the API via Swagger UI


The integrated Swagger UI (/v1/api/docs) provides direct access to the API.


Functions:

  • execute API requests in the browser

  • access configured models

  • verify authentication and responses

  • debug integrations


The documentation is generated from the running instance and reflects the actual system configuration.


Administration and Communication


Message of the Day


Administrators can provide centralized information:

  • maintenance windows

  • new features

  • internal updates

Properties:

  • visible to all users

  • time-controlled

  • multilingual


Group Management


User and permission management has been adjusted:

  • direct group editing

  • live search

  • immediate application of changes

  • clear overview of structures


Optimized for Mobile Use


basebox is usable on mobile devices:

  • stable chat functionality

  • optimized input

  • adapted navigation


Security and Compliance


basebox is designed for environments handling critical data.


Enhancements in 1.7.0:

  • automated security scanning (Trivy)

  • updated identity management (Keycloak 26.5.6)

  • transactional database migrations with rollback


These measures reduce operational risk and support compliance requirements.


Getting Started


The API can be used in a few steps:

  1. create an API token

  2. test access via Swagger UI (/v1/api/docs)

  3. integrate using OpenAI-compatible libraries


Conclusion


basebox 1.7.0 reduces integration effort and operational costs for self-hosted AI.


Organizations can use established standards while maintaining:

  • control over data

  • compliance with regulations

  • independence from hyperscalers


Access the documentation and test the API directly via /v1/api/docs on your basebox instance.
