Rational Core is the technological backbone of Rational AI — an open-source ecosystem designed for full data sovereignty, compliance, and scalability.
It enables organizations to develop and deploy AI applications with complete control over infrastructure, models, and costs, ensuring transparency and interoperability across environments.

Full Lifecycle Governance
Create, manage, and govern every stage of your AI applications — from data ingestion to model deployment — through Rational’s integrated Governance module.
Monitor usage, costs, and performance analytics across all AI systems and touchpoints.


REST API Model Management
Easily deploy, update, and monitor AI models with Rational’s Model Registry, a centralized hub to configure LLMs:
- proprietary: we develop and fine tune propietary LLMs on organization data, increasing internal IP and creating a key differentiator lever
- open-source: LLaMA 4, Mistral Large, Mixtral‑8x22B, DeepSeek R1, GPT‑OSS‑120B, Qwen3‑235B, Falcon, BLOOM, GPT‑NeoX, and more
- commercial: OpenAI, Anthropic, Gemini, and more.
No Lock-in Architecture
Rational Core is fully open-source and licensed under Apache 2.
Deploy on your preferred infrastructure — on-premise or in any major cloud — and maintain full ownership of your models, data, and workflows.

One ecosystem, total control.
Transparency
Every model, dataset, and decision is traceable.
Security
Built-in compliance with GDPR, AI Act, and enterprise standards.
Freedom
Open architecture with no vendor lock-in or hidden dependencies.
