Subprocessors & Upstream Providers
Transparent directory of infrastructure partners and upstream AI model providers selectable through the Zopyr router.
Routing Control: Upstream AI providers only receive requests when you select their models or allow them in your routing policy. Use provider.only or provider.ignore on any API call for strict provider pinning.
1. On-Demand Upstream AI Model Providers
When you invoke a specific model slug (for example, openai/gpt-6.1-sol-pro, anthropic/claude-opus-5.5, or google/gemini-4-argon), Zopyr routes the anonymized inference payload to the corresponding upstream model provider.
2. Core Platform Infrastructure & Notifications
Zopyr hosts its primary gateway, PostgreSQL ledger, and Redis clusters on hardened cloud infrastructure with encrypted backups and strict network segmentation.
