About ai&
ai& is a sovereign AI stack built in Japan that lets teams run frontier AI models and deploy apps with data resident in-country. It targets developers, product teams, and ops groups seeking fast, privately hosted AI with an end-to-end workflow from inference to live deployment.

Key Features
To understand how it fits into real-world workflows, think of the way it combines model serving, application deployment, and secure hosting in one environment:
Single API for frontier models
Run frontier models through a single API, reducing integration complexity and vendor friction.
Japan-hosted, data-resident infrastructure
All data stays in Japan with no cross-border data egress; no infra to manage.
End-to-end deployment stack
Inference, compute, and live deployment share the same environment for 1-click deployment.
Post-training refinements for frontier models
Open models are tuned for domain knowledge, reasoning, speed, and language.
Summary
Best for product and engineering teams delivering customer-facing AI apps, AI/ML engineers prototyping frontier models, and ops teams needing Japan-hosted, sovereign hosting.
