With Arcium Blackthorn™, models run and train over data that is never decrypted. Inputs, weights, and outputs stay sealed, to the host and everyone else, at production speed.
Encrypted execution unlocks the AI workloads that sensitive data could never reach. Here is what becomes possible.
Sending data to a model means handing it to whoever runs the model. Your prompts, your documents, your users' records are all visible to the host. For regulated, proprietary, or personal data, that rules most AI out entirely.
Blackthorn runs inference over data that stays encrypted end to end. Inputs, model weights, and outputs are never exposed, to the host or anyone else, yet the computation stays verifiable. The most secure way to deploy a model, at production speed.
Serve models on sensitive inputs without ever seeing them. Healthcare, finance, and enterprise workloads that could never touch a hosted model can now run confidentially.
Training and fine-tuning need data, and the best data is the data no one is allowed to share. Proprietary datasets, regulated records, and competitive signals stay locked away, so models are trained on far less than exists.
Blackthorn trains and fine-tunes models over encrypted data. The dataset never leaves its owner in the clear and the resulting weights stay sealed, while the training run itself remains verifiable.
Fine-tune on data you could never centralize. Build models on the full picture, regulated, proprietary, and personal data included, without any party exposing it.
The highest-value models would be trained across organizations: banks pooling fraud signals, hospitals pooling outcomes, rivals pooling threat data. None of them can hand their data to the others, so the model never gets built.
Multiple parties compute over the same encrypted data at once, under maliciously secure MPC. Each contributes its data without ever revealing it, and no single party, not even the host, can read the combined inputs.
Train shared models across competitors and institutions. Joint fraud detection, collaborative research, and federated intelligence over data that stays private to its owner.
The fastest and most secure confidential inference platform in the world, combining maliciously secure MPC with GPU confidential computing so models run over encrypted data at production speed.
