Same API key and billing flow

This page exists for direct linking, onboarding, and SEO. The same model row powers /v1/models, the public catalog, the app pricing screen, and request validation for /v1/chat/completions.

Why use this model through UAI

The same model route, but with one account, one balance, and one API shape.

OpenAI-compatible access

Call anthracite-org/magnum-v4-72b with the same UAI API key, the same /v1/chat/completions shape, and the same request validation used across the rest of the catalog.

Shared pricing and billing

Pricing, balance, and request history stay consolidated in one UAI account instead of spreading usage across separate Anthracite Org dashboards.

Live synced catalog row

This page is generated directly from the synced active model row, so its pricing, provider metadata, and availability stay aligned with the catalog and gateway validation.
