Terms of Service

Last updated: August 3, 2026

These terms govern your access to and use of Nullstack, an open-model regional inference service provided by NullStack.

1. The Service

Nullstack provides high-throughput API endpoints for open-weight artificial intelligence models, automated CLI launchers for coding agents, and optional web search integrations. Access is provided via API keys tied to your active subscription or usage balance.

2. Acceptable Use

You agree not to use Nullstack for unlawful activities, to generate content prohibited by applicable model licenses, or to interfere with the security or stability of our infrastructure. You may not attempt to probe, scan, or compromise our routing gateways.

3. Data Handling and Zero Retention

Nullstack does not retain, store, or log prompt text, completion text, or request bodies. Content exists only in volatile GPU memory during the execution of your request. Furthermore, your data is never used to train, fine-tune, or evaluate machine learning models.

4. Inference Capacity and Providers

Inference runs on GPU and TPU capacity operated by NullStack and, when capacity limits require, on certified third-party infrastructure providers (e.g., SOC 2 Type II, ISO/IEC 27001 audited) under strict contractual non-retention and GDPR-aligned data processing terms.

5. Regional Processing

All requests are authenticated and routed by our LiteLLM gateway in the European Union. Your API key configuration determines whether model inference is permitted to run in Europe, the United States, or either region. If no permitted deployment is available in your specified region, the request will fail rather than execute in an unpermitted region.

6. Region Scope

Region selection binds model inference only. It does not dictate where account administration, billing (via Dodo Payments), or authentication (via Clerk) processing occurs.

7. Billing, Tokens, and Usage Packs

Subscriptions (Pro at $20/month, Max at $60/month) provide expected monthly token allowances. One-time usage packs ($5 to $100) can be added at any time and remain valid for 90 days from purchase. Web search queries are billed separately at $0.02 per query.

8. Availability and Changes

We strive to maintain high service reliability. We may update model weights, endpoints, or terms with prior notice. For questions regarding these terms, contact hi@nullstack.in.
