Bring your own key (BYOK)
Use your own Anthropic or OpenAI key so model usage is billed directly by your provider with no Syncanix markup. Keys are write-only and encrypted at rest.
With bring-your-own-key (BYOK), Syncanix sends your assistant’s traffic through your own language-model account instead of ours. Your provider bills you directly for tokens, and Syncanix adds no markup.
What BYOK does
You add a provider API key to your workspace, and Syncanix uses it for the model calls your assistant makes. You can set a key per environment, so development and production stay separate.
- Anthropic
- Use your own Anthropic API key for Claude models.
- OpenAI
- Use your own OpenAI API key for OpenAI models.
Adding a key
Add a key from Settings → BYOK in the dashboard, for each provider and environment you want to use.
- Open BYOK settingsGo to Settings → BYOK and choose the environment (development or production).
- Choose a providerSelect Anthropic or OpenAI, depending on which models you want to run.
- Paste your keyPaste the provider API key and save. Syncanix starts using it for that environment right away.
If your key fails
You choose what happens if your provider key is missing, invalid, or rejected:
- Fall back to managed (default)
- If the BYOK call can’t go through, Syncanix completes it on managed model access so your assistant keeps answering. Those calls are billed as managed usage.
- Fail closed
- If you prefer that nothing ever runs outside your own account, the request stops instead of falling back.
How keys are stored
Keys are encrypted at rest and kept separate per workspace, provider, and environment. They are used only to make model calls on your behalf. See the Trust Center for our security commitments.
