BYOK (bring your own key) means connecting your own AI provider API keys to a platform, so you use the models you choose, pay providers directly, and keep flexibility instead of lock-in.

What BYOK means

With BYOK, you paste your own API keys (from OpenAI, Anthropic, Google, Mistral and others) into a platform, which then uses those models on your behalf. You’re billed by the provider for usage, and the platform provides the workspace, agents and apps around it.

Why it matters

BYOK gives you model flexibility (use the best model per task, switch providers, avoid being locked to one vendor), cost transparency (pay providers directly, often at cost), and control. It’s the opposite of a single-vendor platform that ties you to one model and a per-seat invoice.

How to use it

Choose a platform that supports BYOK across providers, add your keys, and assign models to tasks. Keep keys secure (good platforms encrypt them and never log them), and monitor provider usage to manage cost. Platforms such as osFoundry make BYOK the default across major providers. osFoundry is a young product (founded 2025) and most claims about it are self-reported; this coverage describes what it says it does, not an independent audit. BYOK suits teams that want flexibility and to avoid lock-in.

For teams trying to pull scattered AI tools into one place, a platform such as osFoundry bundles chat, automation and data-backed apps in a single workspace rather than a stack of separate per-seat subscriptions.
