Data Residency

Where is your data stored and processed?

Together AI: All inference and fine-tuning workloads processed in US data centres. No EU data residency option. GDPR transfer mechanisms (SCCs) required for European personal data processing.

Hugging Face Inference: Inference Endpoints support EU data centre regions (AWS, Azure, GCP EU zones). Model inference can be kept within the EU for enterprise customers. Free shared inference API uses US infrastructure. Score reflects Inference Endpoints product.

Legal Jurisdiction

Which laws govern the company and your data?

Together AI: Incorporated in Delaware, US. Subject to CLOUD Act. GDPR DPA available for enterprise customers contractually, but US jurisdiction governs. No EU subsidiary structure.

Hugging Face Inference: US incorporation (Delaware) means CLOUD Act applies despite EU data residency options. GDPR DPA available for enterprise customers. EU-US Data Privacy Framework participation. Jurisdiction risk is mitigated but not eliminated by EU data centre options.

Data Retention & Training

Is your data used for model training?

Together AI: Clear policy that customer data and fine-tuning datasets are not used to train shared models. Fine-tuned model weights are customer property. Good baseline for data isolation, but residency limitation remains.

Hugging Face Inference: Inference Endpoints: request data stays in the customer's isolated endpoint; not used for shared model training. Hub: public model and dataset uploads are public by default. Enterprise DPA provides configurable retention controls.

Certifications

ISO 27001, SOC 2, Cyber Essentials, etc.

Together AI: No published ISO 27001, SOC 2 Type II, or independent security certifications as of early 2026. Security practices are self-attested. Significant gap for enterprise procurement in regulated industries.

Hugging Face Inference: Holds SOC 2 Type II certification. ISO 27001 in progress. Strong certifications trajectory for a company of its size and stage. Enterprise customers benefit from cloud provider security certifications (AWS, Azure, GCP) for endpoint infrastructure.

Regulatory Fit

Suitability for regulated industries and professional services

Together AI: Not suitable for GDPR-regulated personal data processing without SCCs and TIA. Good for development, prototyping, and non-personal-data AI workloads. US jurisdiction and absence of certifications limit suitability for regulated EU industries.

Hugging Face Inference: Good fit for EU enterprises using Inference Endpoints with EU data centre regions. US jurisdiction and developing certification portfolio mean additional due diligence is required for strictly regulated industries. One of the better US-based options for EU-sovereign open-source inference.
