AtriumLLM is the neutral AI foundation for business teams and growing companies. One gateway to every LLM and ML model, with policy that knows whether a request carries an HR record or a sales email, and a trace behind every answer. No platform team required.
Designed to route across Azure OpenAI, AWS Bedrock, Google Vertex, Anthropic, OpenRouter and self-hosted models, with your keys or ours.
Every major provider and your own self-hosted models behind one endpoint. Bring your own keys. Routing carries no commercial weight toward any vendor, and any vendor relationship we have is disclosed.
Every request declares its business line, payload type and data class. Policy follows the payload: finance stays in your cloud, HR goes to isolated endpoints. Unknown payload types are rejected, never guessed.
Each response carries a trace ID into the work it produced, so you can link answers to outcomes and see cost per task by business line.
Your apps and people call Atrium instead of model providers. Change a model in the registry and no app has to redeploy.
Describe what flows through your business: invoices, employee records, call transcripts. Each type names its schema and its sensitive fields.
Allowed models, data handling and spend caps by business line, group and user. Every change is versioned, attributed and reversible.
Atrium picks the model, falls back when a provider fails, and reports cost and outcomes by business line.
Chat is only part of the picture. Atrium serves embeddings, predictions and transcription through typed endpoints, with ML routes pinned to a model version and promoted on accuracy, not swapped on a whim.
Artifacts, traces and outcomes belong to you on every tier: isolated per tenant, fully exportable, never used for training. Choose how far inference sovereignty goes, and we only claim what your tier delivers.
Your dedicated instance, run by us
Isolated compute and data per customer. Frontier model APIs with your keys or ours. Our operators can access the instance to run it.
Deployed in your VPC
You control the infrastructure. Prompts reach only the model vendors you choose, under your terms with them.
Self-hosted open-weight models
Nothing leaves your environment. This is the only tier where we say that, because it is the only tier where it is true.
Your data is never used to train models.
We never read your data outside a support request you approve.
No routing bias toward any model vendor.
Sovereignty claims match the tier you deploy.
Atrium is in early access. Join the list and we’ll reach out as instances open up.
