How pricing works

CorvusLLM deducts usage from prepaid balance using its listed input, output, cache-read, and cache-write rates where applicable. Official prices are shown as comparison references, not invoices from the provider.

Data handling warning

Do not send sensitive or regulated data through shared API proxies. Use direct providers or enterprise-reviewed infrastructure for regulated workloads.

Setup paths

Use the exact base URL and slug

Start with the setup guide that matches your tool, then switch only the model parameter when changing rows in this family.

Compare pricing

Check cost before top-up

Use the calculator and source-linked tracker together before moving real workloads onto a third-party proxy route.

Compare a small test before scaling.

Use a low-risk prompt, confirm the exact model slug, then compare output quality and billed usage before larger workloads.
