Build, run and scale AI, from open models to governed agents
One API key and a drop-in OpenAI SDK replacement unlock 30+ open models across text, reasoning, coding, vision, embeddings, speech-to-text, text-to-speech, image and video.
Run agents connected to company context and tools with scoped memory, tool permissions, human approvals and an auditable decision trail.
Reserve NVIDIA, AMD or Tenstorrent capacity for VMs, fine-tuning and production inference when shared serverless endpoints are not enough.
AI Factory supports VPC, on-premises and air-gapped installs, with zero data retention, an EU option, SOC 2 Type II and GDPR alignment.

A blockchain-powered AI operating system for decentralized app development
Ratio1 DNA is a distributed neuro-symbolic autonomous processing framework with encrypted inference and learning, designed to keep training and inference private across many nodes.
A low-code layer and a library of core apps let teams assemble and ship AI projects quickly, regardless of project scope or in-house infrastructure expertise.
The $R1 utility token pays for GPU compute, resource provisioning and license acquisition across the ecosystem, with no platform fee taken on deployments.
Anti-inflationary Node Deeds let participants link a license to a node and earn from contributing compute, with pricing that rises as demand grows.
