Inside the Network

Know What
Powers Your AI.

Katara Cortex combines approved model bundles, provider validation, and clear usage records so you can understand what serves your requests and what you’re paying for.

  • Verified Model Bundles

    Pinned model weights, tokenizers, and runtimes define what each provider must run.

  • Provider Validation

    Providers are tested with known prompts and checked against the bundle’s requirements.

  • Transparent Usage

    Request records report token usage and the cost in USDC, so you can see what you paid for.
