Bring your own key
Connect your own Anthropic, OpenAI, or Gemini key on any plan and pause credit usage entirely.

Bring Your Own Key (BYOK) lets you run AI generation on your own provider key instead of sprintrr's credits.
Eligibility
BYOK is available on every plan, including the free trial — there's no upgrade required. When BYOK is on, generation runs on your own key and consumes no sprintrr credits; your balance is preserved.
Supported providers
| Provider | Where to get a key | Default model |
|---|---|---|
| Anthropic (Claude) | console.anthropic.com/settings/keys | Claude Sonnet 5.5 (claude-sonnet-5-5) |
| OpenAI | platform.openai.com/api-keys | GPT-4o mini (gpt-4o-mini) |
| Google Gemini | aistudio.google.com/app/apikey | Gemini 3.1 Flash-Lite (gemini-3.1-flash-lite) |
The default is the Recommended row in each provider's Model list in Settings → Your AI keys. sprintrr's prompts are tuned for Claude Sonnet 5.5; other models work, and quality varies. To pin a different model, pick it from the curated list for that provider, or choose Custom… and type a model id. Gemini 3.1 Flash-Lite retires on 7 May 2027; from that date, keys that use it run on Gemini 3.5 Flash-Lite automatically.
You can also switch between sprintrr credits and your active BYOK provider on a per-generation basis from the generate modal (see AI Generation → Choose your AI source per generation).
The Quality / Speed toggle in the generate modal only applies to the sprintrr-credits path. While BYOK is active, the toggle stays visible but goes inert (both buttons dim and disabled) — your BYOK key is already the source, so the mode picker has nothing to choose between.
How credits interact
While BYOK is on, your monthly sprintrr credits are paused — your balance stays intact and is not consumed. You pay your AI provider directly for usage. Turn BYOK off to resume using sprintrr credits.
note:
Pausing means preservation, not loss: your credit balance is untouched while BYOK is active and is available again the moment you disable BYOK.
Adding a key
In Settings → Your AI keys:
- Under keys, find the provider, paste your API key and, if you want, pick a Model.
- Click Test & save key. The key is validated with a live test call before it is stored — an invalid key is rejected immediately.
- Turn on Use your own AI key. When you have keys for more than one provider, choose the Active key.
To switch a saved key to another model, pick the model and paste the key again: sprintrr tests the key with the new model before it saves the change.
Security
- Keys are encrypted at rest with AES-256-GCM using a server-side encryption secret; the raw key is never exposed back to the browser.
- Only a short hint (first/last few characters) is stored for display so you can recognize which key is configured.
- You can replace or delete a provider key at any time; disabling BYOK stops it being used without deleting it.
