If you already pay OpenAI, Anthropic, or Google directly, you should not pay full retail again to use those models through ToRun. Bring Your Own Key (BYOK) is how that works.
How it works
Add a provider API key on the BYOK page in your account. The key is encrypted at rest immediately; the plaintext never appears in the UI again and never leaves the backend. From then on, eligible requests to that provider route through your key — the provider bills you at their prices, and ToRun charges only its service margin for the routing, tooling, memory, and billing layers around the call.
What does not change
- Routing — capability-first model selection works the same; your key is simply preferred when the chosen model belongs to that provider.
- The ledger — every BYOK call still produces a billing record, so the math is checkable.
BYOK is the honest deal: pay the provider what the provider charges, pay us for what we actually add.
Correction, November 2026: an earlier version of this post described three BYOK pricing tiers and a fallback to platform routing when your key hits a rate limit. Neither exists: every BYOK call is billed at one BYOK platform fee.
